Mitochondrial DNA-associated Leigh syndrome is a progressive brain disorder that usually appears in infancy or early childhood. Affected children may experience vomiting, seizures, delayed development, muscle weakness, and problems with movement. Heart disease, kidney problems, and difficulty breathing can also occur in people with this disorder. Mitochondrial DNA-associated Leigh syndrome is a subtype of Leigh syndrome and is caused by changes in mitochondrial DNA. Mutations in at least 11 mitochondrial genes have been found to cause mtDNA-associated Leigh syndrome. This condition has an inheritance pattern known as maternal or mitochondrial inheritance. Because mitochondria can be passed from one generation to the next only through egg cells (not through sperm cells), only females pass mitochondrial DNA-associated Leigh syndrome to their children.

Glutaric acidemia type III is a rare metabolic condition characterized by persistent, isolated accumulation or excretion of glutaric acid. No specific phenotype has been described, as symptoms vary and some individuals remain symptom-free. Unlike other types of glutaric acidemia, this type is caused by a peroxisomal rather than a mitochondrial dysfunction. Mutations in the C7ORF10 gene on chromosome 7p14 have been identified in some people with glutaric acidemia type III and the condition follows an autosomal recessive pattern of inheritance. Treatment with riboflavin has been helpful in some patients.

Cherubism is a rare disorder characterized by abnormal bone tissue in the lower part of the face. The enlarged bone is replaced with painless, cyst-like growths that give the cheeks a swollen, rounded appearance and frequently interfere with normal tooth development. The condition may be mild or severe. People with the severe form may have problems with vision, breathing, speech, and swallowing. Many adults with cherubism have a normal facial appearance. Most people with cherubism do not any other signs and symptoms. The condition is inherited in an autosomal dominant fashion and is caused by mutations in the SH3BP2 gene. , in most cases.

What is (are) Cherubism ?

Cherubism is characterized by abnormal bone tissue in the lower part of the face. Beginning in early childhood, both the lower jaw (the mandible) and the upper jaw (the maxilla) become enlarged as bone is replaced with painless, cyst-like growths. These growths give the cheeks a swollen, rounded appearance and often interfere with normal tooth development. In some people the condition is very mild and barely noticeable, while in other cases are severe enough to cause problems with vision, breathing, speech, and swallowing. Enlargement of the jaw usually continues throughout childhood and stabilizes during puberty. The abnormal growths are gradually replaced with normal bone in early adulthood. As a result, many affected adults have a normal facial appearance. The Human Phenotype Ontology provides the following list of signs and symptoms for Cherubism.

Frontal fibrosing alopecia (FFA) is a form of lichen planus follicularis that is characterized primarily by slowly progressive hair loss (alopecia) and scarring on the scalp near the forehead. In some cases, the eyebrows, eye lashes and/or other parts of the body may be involved, as well. Although it has been suggested that FFA may be due to hormonal changes or an autoimmune response, the exact cause of this condition is not yet known. There is currently no cure for FFA; however, treatment with certain types of medications may stop or slow hair loss in some cases.

What is (are) Frontal fibrosing alopecia ?

Frontal fibrosing alopecia (FFA) is characterized primarily by hair loss (alopecia) and scarring on the scalp near the forehead. The band of hair loss on the front and sides of the scalp is usually symmetrical and slowly progressive (worsening over time). The skin in the affected area often looks normal but may be pale, shiny or mildly scarred. Approximately half of all affected people experience loss of eyebrows, as well. Less commonly, the eyelashes may also be involved. Some people with FFA develop hair loss in areas other than the scalp and face. In some cases, women with FFA also have female pattern hair loss, which is associated with thinning of hair on the scalp due to increased hair shedding and/or a reduction in hair volume.

What are the symptoms of Frontal fibrosing alopecia ?

The exact underlying cause of frontal fibrosing alopecia (FFA) is unknown. FFA is thought to be an autoimmune condition in which an affected persons immune system mistakenly attacks the hair follicles (structures in the skin that make hair). Scientists also suspect that there may be a hormonal component since the condition most commonly affects post-menopausal women over age 50.

What causes Frontal fibrosing alopecia ?

Frontal fibrosing alopecia is not thought to be inherited in most cases. It rarely affects more than one person in a family.

Is Frontal fibrosing alopecia inherited ?

Frontal fibrosing alopecia is often suspected based on the presence of characteristic signs and symptoms. The diagnosis can be confirmed by examining a small sample of skin (skin biopsy) from the affected area. In some cases, laboratory studies may be ordered to rule out other conditions that cause similar features.

How to diagnose Frontal fibrosing alopecia ?

Unfortunately, there is currently no cure for frontal fibrosing alopecia (FFA). Because the hair loss associated with this condition is thought to be caused by inflammation of hair follicles, treatment often involves using anti-inflammatory medications or ointments, such as corticosteroids or hydroxychloroquine (brand name Plaquenil), to reduce inflammation and suppress the bodys immune system. Medications that block the production of the male hormone 5-alpha reductase have been reported to stop further hair loss in some women. Researchers continue to question whether treatment is effective or if hair loss in FFA just stops naturally.

Chondrocalcinosis 2 is a rare condition characterized by the accumulation of calcium pyrophosphate dihydrate crystals in and around the joints. A buildup of these crystals can lead to progressive (worsening over time) joint damage. Some affected people may not have any signs or symptoms of the condition. Others experience chronic joint pain or sudden, recurrent episodes of pain, stiffness and/or swelling of the joints. Although chondrocalcinosis 2 can affect people of all ages, it is most commonly diagnosed in early adulthood (age 20-40 years). It is caused by changes (mutations) in the ANKH gene and is inherited in an autosomal dominant manner. There is no cure for the condition and treatment is symptomatic.

What is (are) Chondrocalcinosis 2 ?

The signs and symptoms of chondrocalcinosis 2 vary from person to person. Some affected people may not have any symptoms of the condition aside from the appearance of calcium deposits on joint x-rays. Others experience chronic pain in affected joints and/or the back if calcium deposits develop around the bones of the spine. Chondrocalcinosis 2 can also be associated with sudden, recurrent episodes of joint pain, stiffness and/or swelling that can last anywhere from several hours to several weeks. These episodes can lead to limited range of motion in the affected joint or even ankylosis (fixation of joint in place). Although almost any joint in the body can be affected, symptoms are often confined to a single knee, wrist, hip or shoulder. The Human Phenotype Ontology provides the following list of signs and symptoms for Chondrocalcinosis 2.

In these cases, the sign or symptom may be rare or common.

What are the symptoms of Chondrocalcinosis 2 ?

Chondrocalcinosis 2 is caused by changes (mutations) in the ANKH gene. This gene encodes a protein that helps transport pyrophosphate (a substance that regulates bone formation). Mutations in ANKH can cause high levels of pyrophosphate and calcium pyrophosphate dihydrate crystals to accumulate in the cartilage of joints. The buildup of these crystals weakens cartilage and causes it to break down more easily. This leads to the many signs and symptoms associated with chondrocalcinosis 2.

What causes Chondrocalcinosis 2 ?

Chondrocalcinosis 2 is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with chondrocalcinosis 2 has a 50% chance with each pregnancy of passing along the altered gene to his or her child.

Is Chondrocalcinosis 2 inherited ?

A diagnosis of chondrocalcinosis 2 is often suspected based on characteristic signs and symptoms. Specialized testing, such as synovial fluid analysis, can then be ordered to confirm the diagnosis. In synovial fluid analysis, a small sample of the fluid that surrounds affected joints is removed and examined to determine if calcium pyrophosphate dihydrate crystals are present. In most cases, x-rays can be used to identify calcium deposits in the cartilage of joints.

How to diagnose Chondrocalcinosis 2 ?

There is currently no cure for chondrocalcinosis 2. Unfortunately, the accumulation of calcium pyrophosphate dihydrate crystals can not be prevented and once present, these crystals can not be removed from affected joints. Therapies are available to manage the signs and symptoms of the condition. During episodes of joint pain, stiffness, and/or swelling, the following treatments may be recommended to relieve symptoms: joint aspiration (draining of fluid from the affected joint), corticosteroids injections, and/or nonsteroidal anti-inflammatory drugs (NSAIDS) such as aspirin or ibuprofen. Small doses of a medication called colchicine or NSAIDS are sometimes prescribed to people with frequent and severe attacks in an attempt to prevent future episodes; however, this therapy is not effective in all cases.

McCune-Albright syndrome (MAS) is a disease that affects the bones, skin, and several hormone-producing (endocrine) tissues. It is characterized by replacement of normal bone tissue with areas of abnormal fibrous growth (fibrous dysplasia); patches of abnormal skin coloring with jagged borders (cafe-au-lait spots); and abnormalities in the glands that regulate the bodys rate of growth, sexual development, and other metabolic functions (multiple endocrine dysfunction). MAS is caused by a change (mutation) in the GNAS gene that occurs by chance very early in development. As a result, some of the bodys cells have a normal version of the GNAS gene, while other cells have the mutated version. This phenomenon is called mosaicism. The severity of MAS and its features depend on the number and location of cells that have the mutated GNAS gene. Because MAS occurs by chance, it is not inherited or passed down from one generation to the next.

What is (are) McCune Albright syndrome ?

People with McCune Albright syndrome (MAS) may have symptoms related to bones, the endocrine system, and/or skin. The symptoms can range from mild to severe. Bone symptoms may include: Polyostotic fibrous dysplasia: This is when normal bone is replaced by softer, fibrous tissue. Polyostotic means the abnormal areas may occur in many bones; often they are confined to one side of the body. Replacement of bone with fibrous tissue may lead to fractures, uneven growth, and deformity. When it occurs in skull and jaw it can result in uneven growth of the face. This may also occur in the long bones; uneven growth of leg bones may cause limping. Abnormal curvature of the spine (scoliosis) Cancer: Bone lesions may become cancerous, but this happens in less than 1% of people with MAS. Endocrine symptoms may include: Early puberty: Girls with MAS usually reach puberty early. They often have menstrual bleeding by age 2 (as early as 4-6 months in some), many years before characteristics such as breast enlargement and pubic hair growth are evident. This early onset of menstruation is believed to be caused by excess estrogen, a female sex hormone produced by cysts that develop in one of the ovaries. Less commonly, boys with MAS may also experience early puberty. Enlarged thyroid gland: The thyroid gland may become enlarged (a condition called a goiter) or develop masses called nodules. About half of affected individuals produce excessive amounts of thyroid hormone (hyperthyroidism), resulting in a fast heart rate, high blood pressure, weight loss, tremors, sweating, and other symptoms. Increased production of growth hormone: The pituitary gland may produce too much growth hormone. This can result in acromegaly, a condition characterized by large hands and feet, arthritis, and distinctive facial features that are often described as coarse. Cushings syndrome: Rarely, individuals with MAS produce too much of the hormone cortisol in the adrenal glands. Cushings syndrome causes weight gain in the face and upper body, slowed growth in children, fragile skin, fatigue, and other health problems. Skin symptoms may include: Cafe-au-lait spots: Individuals with MAS usually have light brown patches of skin called cafe-au-lait spots. Like the bone lesions, these spots often appear on only one side of the body. Most children have these spots from birth and the spots rarely grow. There are usually not any medical problems caused by these skin changes. The Human Phenotype Ontology provides the following list of signs and symptoms for McCune Albright syndrome.

What are the symptoms of McCune Albright syndrome ?

McCune Albright syndrome (MAS) is caused by a change (mutation) in the GNAS gene. This gene provides instructions for making part of a protein that ultimately influences many cell functions by regulating hormone activity. GNAS gene mutations that cause MAS result in a protein that causes the enzyme adenylate cyclase to be constantly turned on. This, in turn, leads to over-production of several hormones, resulting in the signs and symptoms of MAS.

What causes McCune Albright syndrome ?

McCune Albright syndrome (MAS) is not inherited. It is caused by a random change (mutation) in the GNAS gene that occurs very early in development. As a result, some of the bodys cells have a normal version of the GNAS gene, while other cells have the mutated version. This phenomenon is called mosaicism. The severity of this disorder and its specific features depend on the number and location of cells that have the mutated GNAS gene. This mutation is not passed on to any of the affected individuals children.

Is McCune Albright syndrome inherited ?

Although there is no cure for McCune Albright syndrome (MAS), drug treatments may help some of the endocrine symptoms, and surgery can help repair some of the bone problems. Generally, treatment depends on what tissues are affected as well as the severity. Surgery may be needed to manage complications associated with fibrous dysplasia, such as progressive visual disturbance, severe pain, and severe disfigurement. Surgery may also be needed to manage associated endocrine abnormalities and/or cancers. Bisphosphonates are frequently used to treat fibrous dysplasia. Strengthening exercises are recommended to help maintain musculature around the bones and minimize the risk of fracture. Treatment of all endocrine symptoms, whether by hormone inhibitors or surgery, is commonly required. More detailed information about the management of MAS syndrome is available on Medscape References Web site.

Congenital anosmia is a very rare condition in which people are born with a lifelong inability to smell. It may occur as an isolated abnormality (no additional symptoms) or be associated with a specific genetic disorder (such as Kallmann syndrome and congenital insensitivity to pain). Scientists suspect that isolated congenital anosmia occurs due to abnormal development of the olfactory system (the sensory system used for sense of smell) prior to birth. This may include abnormalities of the nasal cavity, disruptions in the pathway that carries information from the nose to the brain, and/or malformations of the portion of the brain that processes sense of smell. Unfortunately, there is currently no known cure or treatment for congenital anosmia.

What are the symptoms of Congenital anosmia ?

Congenital anosmia may occur as an isolated abnormality or be associated with specific genetic disorders (such as Kallmann syndrome and congenital insensitivity to pain). Most cases of isolated congenital anosmia (not associated with additional symptoms) occur sporadically in people with no family history of the condition. In these people, the exact underlying cause of the condition is unknown. Most likely, there is more than one cause. Scientists suspect that the condition occurs due to abnormal development of the olfactory system (the sensory system used for sense of smell) prior to birth. This may include abnormalities of the nasal cavity, disruptions in the pathway that carries information from the nose to the brain, and/or malformations of the portion of the brain that processes sense of smell. Rarely, isolated congenital anosmia can affect more than one family member. This suggests that there may be a genetic component in some cases. One study found that some people affected by isolated congenital anosmia have changes (mutations) in PROKR2 or PROK2, two genes that have previously been reported in people with Kallmann syndrome (an inherited condition associated with congenital anosmia and other symptoms). To date, no other disease-causing genes have been identified.

What causes Congenital anosmia ?

Most cases of isolated congenital anosmia (not associated with additional symptoms) occur sporadically in people with no family history of the condition. Rarely, more than one family member may be affected. In these families, the condition appears to be inherited in an autosomal dominant manner with reduced penetrance. Congenital anosmia can also by associated with specific genetic disorders such as Kallmann syndrome and congenital insensitivity to pain. In these cases, the inheritance varies based on the associated condition. For example, Kallmann syndrome can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive manner depending on the underlying genetic cause (it can be caused by mutations in several different genes). Congenital insensitivity to pain follows an autosomal recessive pattern of inheritance.

Is Congenital anosmia inherited ?

Isolated congenital anosmia (not associated with other symptoms) is a diagnosis of exclusion. This means that the diagnosis is made in people with suspicious signs and symptoms once other conditions that cause similar features have been ruled out. When an affected person has no recollection of ever being able to smell, the following tests may be ordered to support a diagnosis of congenital anosmia: A thorough physical examination and medical history to look for other conditions that may interfere with the sense of smell Smell tests, particularly those that determine the smallest amount of odor that someone can detect Brain Imaging (such as CT scan and MRI scan) as some people with congenital anosmia have malformations in the portion of the brian that processes smells Nasal endoscopy to look for abnormalities of the nasal cavity which may interfere with sense of smell Olfactory nerve testing to evaluate disruptions in the pathway that carries information from the nose to the brain

Meningoencephalocele is a type of encephalocele, which is an abnormal sac of fluid, brain tissue, and meninges (membranes that cover the brain and spinal cord) that extends through a defect in the skull. There are two main types of meningoencephalocele, which are named according to the location of the sac. The frontoethmoidal type is located at the frontal and ethmoid bones while the occipital type is located at the occipital bone. Hydrocephalus, abnormalities of the eyeball and tear duct, and other findings have been associated with the condition. Some affected individuals have intellectual or physical disabilities while others have normal development and abilities. The condition is typically congenital (present at birth) but has been reported to develop by chance in older individuals in rare cases. The underlying cause of the condition is uncertain, but environmental factors are thought to play a role. Treatment depends on the size, location and severity of the defect but mainly includes magnetic resonance imaging (MRI) to determine the severity of the defect, followed by surgery to repair it.

What is (are) Meningoencephalocele ?

The exact cause of meningoencephalocele is not known. Some studies have suggested that environmental factors could play a role in causing the condition. Exposure during pregnancy to aflatoxins, toxins produced by a mold that grows in nuts, seeds, and legumes, has been proposed to be a possible cause in some cases. However, its potential role in causing the condition is unclear. It has also been suggested that folate deficiency during pregnancy might play a role, because the condition is so closely related to spina bifida, which can be caused by folate deficiency. However, there have been no studies regarding the relationship of maternal folate deficiency and meningoencephalocele. Further studies are needed to to clarify what may cause the condition.

What causes Meningoencephalocele ?

Meningoencephalocele is not thought to be an inherited condition. Studies have proposed that meningoencephalocele is likely a multifactorial defect. This means that both environmental factors and multiple genes may interact with each other to cause the condition. Studies have suggested that environmental factors probably play an important role. This information is supported by the fact that several studies have not identified the condition among close relatives of affected individuals. To date, there have been no genes identified that are likely to play a strong part in causing the condition.

Actinomycosis is a chronic bacterial infection that commonly affects the face and neck. It is usually caused by an anaerobic bacteria called Actinomyces israelii. Actinomyces are normal inhabitants of the mouth, gastrointestinal tract, and female genital tract, and do not cause an infection unless there is a break in the skin or mucosa. The infection usually occurs in the face and neck, but can sometimes occur in the chest, abdomen, pelvis, or other areas of the body. The infection is not contagious.

Holt-Oram syndrome is a genetic condition characterized by skeletal abnormalities of the hands and arms (upper limbs) and heart problems. Affected people have at least one bone abnormality in the wrist, many of which can be detected only by X-ray. Additional skeletal abnormalities may also be present. About 75% of affected people have heart problems, including congenital heart defects and/or cardiac conduction disease (an abnormality in the electrical system that coordinates contractions of the heart chambers). Holt-Oram syndrome is caused by mutations in the TBX5 gene and is inherited in an autosomal dominant manner. Most cases result from new mutations in the gene and occur in people with no family history of the condition.

What is (are) Holt-Oram syndrome ?

People with Holt-Oram syndrome have abnormally developed bones in their upper limbs. At least one abnormality in the bones of the wrist (carpal bones) is present. Additional bone abnormalities may also be present, such as a missing thumb, a long thumb that looks like a finger, partial or complete absence of bones in the forearm, an underdeveloped bone of the upper arm, and abnormalities of the collar bone or shoulder blades. About 75% of affected people have heart problems, which can be life-threatening. The most common problems are an atrial septal defect (ASD) and a ventricular septal defect (VSD). Some people have cardiac conduction disease, which is caused by abnormalities in the electrical system that coordinates contractions of the heart chambers. Cardiac conduction disease can lead to problems such as a slower-than-normal heart rate (bradycardia) or a rapid and uncoordinated contraction of the heart muscle (fibrillation). The features of Holt-Oram syndrome are similar to those of a condition called Duane-radial ray syndrome but these two disorders are caused by mutations in different genes.

What are the symptoms of Holt-Oram syndrome ?

Holt-Oram syndrome is caused by changes (mutations) in the TBX5 gene. This gene gives the body instructions for making a protein involved in the development of the heart and upper limbs before birth. In particular, this gene seems important for dividing the developing heart into four chambers, and in regulating the development of bones in the arms and hands. When the TBX5 gene doesnt function properly, the features of Holt-Oram syndrome result. In some cases the mutation occurs for the first time in an affected person, while in other cases the mutation is inherited from a parent. However, in both of these cases, there is nothing a parent can do to cause this mutation or condition in a child.

What causes Holt-Oram syndrome ?

Holt-Oram syndrome (HOS) is inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough to cause signs and symptoms of the condition. In most cases, the mutation in the gene occurs for the first time in the affected person and is not inherited from a parent. When a mutation occurs for the first time, it is called a de novo mutation. This is what typically occurs when there is no family history of the condition. A de novo mutation is due to a random change in the DNA in an egg or sperm cell, or right after conception. In some cases, an affected person inherits the mutated copy of the gene from an affected parent. In these cases, the symptoms and severity can differ from those of the affected parent. When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to inherit the condition.

Is Holt-Oram syndrome inherited ?

The diagnosis of Holt-Oram syndrome can be established based on physical features and family history. It can be confirmed through genetic testing looking for mutations in the TBX5 gene. Hand x-rays are usually performed for upper-limb malformations. A family history of this condition and/or cogenital heart malformations is also used as a diagnostic tool as a congenital heart malformation is present in 75% of individuals with Holt-Oram syndrome. An echocardiogram and electrocardiogram can be used to determine the presence and severity of heart defects and/or cardiac conduction disease. Holt-Oram syndrome can be excluded in individuals with congenital malformations involving the following structures or organ systems: ulnar ray only, kidney, vertebra, head and face region, auditory system (hearing loss or ear malformations), lower limb, anus, or eye.

How to diagnose Holt-Oram syndrome ?

The treatment of Holt-Oram syndrome is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists such as pediatricians, surgeons, cardiologists, orthopedists, and/or other health care professionals. Depending upon the severity of any upper limb abnormalities, treatment may consist of corrective or reconstructive surgery, the use of artificial replacements for portions of the forearms and hands (limb prosthetics), and/or physical therapy to help individuals enhance their motor skills. In those with mild cardiac conduction abnormalities, treatment may not be required. In more severe cases, an artificial pacemaker may be used. An artificial pacemaker overrides the hearts impaired electrical conducting system by sending electrical impulses to the heart that keep the heartbeat at a regular rate. Heart abnormalities may also be treated with certain medications, surgery, and/or other techniques. In such cases, the surgical procedures performed will depend upon the location and severity of the abnormalities and their associated symptoms. Affected individuals with heart defects may also be at risk for bacterial infection and inflammation of the lining of the hearts chambers and valves (endocarditis). So antibiotics should be prescribed before any surgical procedure, including dental procedures such as tooth extractions. In addition, because some individuals with certain heart defects may be susceptible to repeated respiratory infections, physicians may closely monitor such individuals to take preventive steps and to institute antibiotic and/or other appropriate therapies should such infections occur. Early intervention is important to ensure that children with Holt-Oram syndrome reach their potential. Special services that may be beneficial to affected children may include physical therapy and/or other medical, social, and/or vocational services.

Dominant optic atrophy (DOA) is an inherited optic nerve disorder characterized by degeneration of the optic nerves. It typically starts during the first decade of life. Affected people usually develop moderate visual loss and color vision defects. The severity varies and visual acuity can range from normal to legal blindness. About 20% of people with DOA have non-ocular features, such as sensorineural hearing loss; myopathy; peripheral neuropathy; multiple sclerosis-like illness; and spastic paraplegia (impaired function of the legs). These cases may be referred to as DOA plus. DOA is inherited in an autosomal dominant manner and may be caused by a mutation in any of several genes, some of which have not been identified. There is currently no way to prevent or cure DOA, but affected people may benefit from low vision aids.

What is (are) Dominant optic atrophy ?

Dominant optic atrophy (DOA) is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition. In some cases, an affected person inherits the mutated gene from a parent. In other cases, the mutation occurs for the first time in an affected person and is not inherited from a parent (a de novo mutation). When a person with a mutation that causes DOA has children, each child has a 50% (1 in 2) chance to inherit the mutation. While a mutation responsible for DOA can cause the condition, not all people with a mutation will develop DOA. This means that DOA has reduced penetrance. There are likely to be other genetic and environmental factors that influence whether a person with a mutation will develop features of DOA. Additionally, not all people who do develop features will be affected the same way, and severity can vary - even within families. This phenomenon is known as variable expressivity. People with questions about genetic risks or genetic testing for themselves or family members are encouraged to speak with a genetics professional.

Is Dominant optic atrophy inherited ?

There is currently no cure for dominant optic atrophy (DOA). Management generally consists of regular eye exams, including measurement of visual acuity, color vision, visual fields and optical coherence tomography (OCT). Currently there is no specific treatment, but low-vision aids in individuals with severely decreased visual acuity can be helpful. A preliminary study published in February 2013 found that several individuals with specific OPA1 mutations who underwent idebenone therapy (which has been used to treat some cases of Leber hereditary optic neuropathy) experienced some improvement of visual function. However, more thorough research is necessary to confirm these findings. Acupuncture is also being studied as a potential treatment. Avoiding tobacco and alcohol intake and certain medications (antibiotics, antivirals), which can interfere with mitochondrial metabolism, may help to slow the progression. Cochlear implants have been shown to markedly improve hearing in individuals with sensorineural hearing loss.

Proximal symphalangism, which is also called Cushings symphalangism, is a rare genetic condition characterized by the fusion of the proximal joints in the hands and feet. These individuals usually have straight fingers and are unable to make a fist. Other joints may also be affected, leading to stiff joints in the elbows, ankles and wrists. Hearing loss due to the fusion of the auditory ossicles (bones in the middle ear) is also a characteristic feature. This condition is inherited in an autosomal dominant pattern and is caused by a mutation in the NOG gene or GDF5 gene.

Neuronal ceroid lipofuscinosis (NCL) refers to a group of conditions that affect the nervous system. Signs and symptoms vary widely between the forms but generally include a combination of dementia, vision loss, and epilepsy. Although the NCLs were historically classified according to their age of onset and clinical features, the most recent classification system is primarily based on their underlying genetic cause. Most forms are inherited in an autosomal recessive manner; however, autosomal dominant inheritance has been reported in one adult-onset form (neuronal ceroid lipofuscinosis 4B). Treatment options are limited to therapies that can help relieve some of the symptoms.

Hereditary hemorrhagic telangiectasia (HHT) is an inherited disorder of the blood vessels that can cause excessive bleeding. People with this condition can develop abnormal blood vessels called arteriovenous malformations (AVMs) in several areas of the body. If they are on the skin, they are called telangiectasias. The AVMs can also develop in other parts of the body, such as the brain, lungs, liver, or intestines. HHT is caused by mutations in the ACVRL1, ENG, and SMAD4 genes. It is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. There is no cure for HHT. Treatment is symptomatic and supportive, with a focus on controlling bleeding, either through surgery or medication.

What are the symptoms of Hereditary hemorrhagic telangiectasia ?

Yes. Although there is not yet a way to prevent the telangiectases or AVMs associated with HHT, most can be treated once they occur. Management includes surveillance for undiagnosed AVMs and treatment for identified complications such as nosebleeds, gastrointestinal bleeding, anemia, pulmonary AVMs, cerebral AVMs, and hepatic AVMs. Treatment of nosebleeds with humidification and nasal lubricants, laser ablation, septal dermoplasty, or estrogen-progesterone therapy can prevent anemia and allow individuals with HHT to pursue normal activities. Individuals with GI bleeding are treated with iron therapy to maintain hemoglobin concentration; endoscopic application of a heater probe, bicap, or laser; surgical removal of bleeding sites; and estrogen-progesterone therapy. Iron replacement and red blood cell transfusions are used to treat anemia. Pulmonary AVMs with feeding vessels that exceed 3. 0 mm in diameter require occlusion. Cerebral AVMs greater than 1. 0 cm in diameter are treated by surgery, embolotherapy, and/or stereotactic radiosurgery. The treatment of choice for hepatic AVMs is liver transplantation. Blood-thinning medications (anticoagulants) and anti-inflammatory agents should be avoided. Some patients may need to take antibiotics during simple dental or surgical procedures. Individual patients and their doctors should make decisions regarding these measures, as necessary. Surveillance includes annual evaluations for anemia and neurologic conditions and re-evaluation for pulmonary AVMs every one to two years during childhood and every five years thereafter. Women with HHT considering pregnancy are screened and treated for pulmonary AVMs; if pulmonary AVMs are discovered during pregnancy, they are treated during the second trimester.

Infectious arthritis is joint pain, soreness, stiffness and swelling caused by a bacterial, viral, or fungal infection that spreads from another part of the body. Depending on the type of infection, one or more joints may be affected. Certain bacteria can cause a form of infectious arthritis called reactive arthritis, which appears to be caused by the immune system reacting to bacteria, rather than by the infection itself. In reactive arthritis, joint inflammation develops weeks, months or even years after the infection. Reactive arthritis happens most commonly after infections of the genital and gastrointestinal tracts. To diagnose infectious arthritis, your health care provider may do tests of your blood, urine, and joint fluid. Treatment includes medicines and sometimes surgery.

Wolfram syndrome, which is also known by the acronym DIDMOAD, is an inherited condition characterized by diabetes insipidus (DI), childhood-onset diabetes mellitus (DM), a gradual loss of vision caused by optic atrophy (OA), and deafness (D). There are two types of Wolfram syndrome (type 1 and type 2) which are primarily differentiated by their genetic cause. Type 1 is caused by changes (mutations) in the WFS1 gene, while type 2 is caused by mutations in the CISD2 gene. Both forms are inherited in an autosomal recessive manner. Treatment is symptomatic and supportive.

What is (are) Wolfram syndrome ?

There are two types of Wolfram syndrome (type 1 and type 2) which have many overlapping features. Wolfram syndrome type 1, which is also known by the acronym DIDMOAD, is characterized by diabetes insipidus (DI), childhood-onset diabetes mellitus (DM), gradual loss of vision due to optic atrophy (OA), and deafness (D). About 65% of affected people will develop all four of these symptoms, while others will only have some of the associated health problems. Other signs and symptoms of Wolfram syndrome type 1 may include: Urinary tract abnormalities Ataxia (problems with coordination and balance) Loss of sense of smell Loss of gag reflex Myoclonus (muscle spasms) Peripheral neuropathy Seizures Depression Impulsive and/or aggressive behavior Psychosis Gastrointestinal problems Intellectual disability Central apnea and central respiratory failure Hypogonadism in males (reduced amounts of the sex hormone testosterone) In addition to the signs and symptoms found in Wolfram syndrome type 1, people with Wolfram syndrome type 2 may also have stomach and/or intestinal ulcers; and a tendancy to bleed excessivly after injuries.

What are the symptoms of Wolfram syndrome ?

There are two types of Wolfram syndrome (type 1 and type 2) which are primarily differentiated by their genetic cause. Changes (mutations) in the WFS1 gene are responsible for approximately 90% of Wolfram syndrome type 1 cases. This gene encodes wolframin, a protein that is important for the proper functioning of the endoplasmic reticulum (the part of a cell that is involved in protein production, processing, and transport). Wolframin helps regulate the amount of calcium in cells, which is important for many different cellular functions. Mutations in WFS1 result in a defective form of wolframin that is unable to perform its normal role. This causes cells to trigger their own death (apoptosis). The death of cells in various organs and other parts of the body results in the signs and symptoms of Wolfram syndrome type 1. A specific mutation in the CISD2 gene causes Wolfram syndrome type 2. Although the exact function of this gene is not known, scientists suspect that it plays an important role in the mitochondria (the part of the cell where energy is produced). Mutations in CISD2 lead to the loss of mitochondria which decreases the amount of energy available to cells. Cells that do not have enough energy die. As in Wolfram syndrome type 1, the death of cells in different parts of the body results in the many health problems associated with Wolfram syndrome type 2. Mutations in mitochondrial DNA may also be a rare cause of Wolfram syndrome in some families.

What causes Wolfram syndrome ?

Wolfram syndrome is inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.

Is Wolfram syndrome inherited ?

A diagnosis of Wolfram syndrome is based on the presence of characteristic signs and symptoms. The identification of a change (mutation) in the WFS1 gene or CISD2 gene confirms the diagnosis. Yes. Clinical genetic testing is available for changes (mutations) in WFS1 and CISD2, the two genes known to cause Wolfram syndrome type 1 and Wolfram syndrome type 2, respectively. Carrier testing for at-risk relatives and prenatal testing are possible if the two disease-causing mutations in the family are known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. It offers information on genetic testing for Wolfram syndrome type 1 and Wolfram syndrome type 2. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

How to diagnose Wolfram syndrome ?

Treatment of Wolfram syndrome is supportive and based on the signs and symptoms present in each person. For example, almost all affected people require insulin to treat diabetes mellitus. People with hearing loss may benefit from hearing aids or cochlear implantation. For more detailed information regarding the treatment and management of Wolfram syndrome, click here.

Hydranencephaly is a rare condition in which the brains cerebral hemispheres are absent and replaced by sacs filled with cerebrospinal fluid (CSF). Affected infants may appear and act normal at birth, but irritability and hypertonia often develop within a few weeks. Other signs and symptoms may include seizures, hydrocephalus, visual impairment, lack of growth, deafness, blindness, paralysis, and intellectual disabilities. Prognosis is typically poor with many affected children dying before one year of age. In rare cases, children may survive for several years or more. It has been suspected to be an inherited condition, although some researchers believe it may be caused by prenatal blockage of the carotid artery where it enters the cranium. Treatment is generally symptomatic and supportive; hydrocephalus may be treated with a shunt.

Unfortunately, there is no definitive treatment for hydranencephaly. Management of the condition typically focuses on the specific signs and symptoms present in the affected individual and is mostly supportive.

Mercury poisoning is a condition that occurs in people who are exposed to toxic levels of the element, mercury. There are three different forms of mercury that can cause health problems: Elemental mercury (also known as liquid mercury or quicksilver) can be found in glass thermometers, electrical switches, dental fillings and fluorescent light bulbs. This form of mercury is generally only harmful when small droplets become airborne and are inhaled. If this occurs, signs and symptoms of poisoning may include metallic taste, vomiting, difficulty breathing, coughing, and/or swollen, bleeding gums. In severe cases, long-term brain damage, permanent lung damage and even death may occur. Inorganic mercury is found in batteries, chemistry labs, and some disinfectants. This form of mercury is harmful when swallowed. Signs and symptoms of inorganic mercury poisoning vary based on the amount consumed, but may include burning in the stomach and throat; vomiting; and/or bloody diarrhea. Inorganic mercury can also affect the kidneys and brain if it enters the blood stream. Organic mercury can be found in fish. Some organisms convert fumes from burning coal into organic mercury. This form of mercury is harmful if inhaled, eaten, or placed on the skin for long periods of time. Long-term exposure to organic mercury may result in skin numbness or pain; tremor; inability to walk well; blindness; double vision; memory problems; seizures; or even death. Treatment is generally supportive and based on the signs and symptoms present in each person. Medications called chelators, which remove mercury and heavy metals from the body, are generally prescribed.

Amelogenesis imperfecta (AI) (amelogenesis - enamel formation; imperfecta - imperfect) is a disorder that affects the structure and appearance of the enamel of the teeth. This condition causes teeth to be unusually small, discolored, pitted or grooved, and prone to rapid wear and breakage. These dental problems, which vary among affected individuals, can affect both primary (baby) teeth and permanent teeth. There are 4 main types of AI that are classified based on the type of enamel defect. These 4 types are divided further into 14 subtypes, which are distinguished by their specific dental abnormalities and by their pattern of inheritance. AI can be inherited in an autosomal dominant, autosomal recessive or X-linked recessive pattern.

What is (are) Amelogenesis imperfecta ?

In general, the both primary and permanent teeth are affected. The enamel tends to be soft and weak, and the teeth appear yellow and damage easily. The defects associated with amelogeneis imperfecta are highly variable and include abnormalities classified as hypoplastic (defects in the amount of enamel), hypomaturation (defect in the final growth and development of the tooth enamel), and hypocalcification (defect in the initial stage of enamel formation followed by defective tooth growth). The enamel in the hypomaturation and hypocalcification types is not mineralized and is thus described as hypomineralized. Traditionally, the diagnosis and classification of amelogenesis imperfecta is based on the clinical presentation and the mode of inheritance. There are four principal types based on the defects in the tooth enamel. These types are subdivided into 14 different subtypes based on the clinical presentation and the mode of inheritance. Detailed information about the signs and symptoms associated with the four major types of amelogenesis imperfecta is available from the UNC School of Dentistry.

What are the symptoms of Amelogenesis imperfecta ?

Amelogenesis imperfecta is caused by mutations in the AMELX, ENAM, and MMP20 genes. These genes provide instructions for making proteins that are essential for normal tooth development. These proteins are involved in the formation of enamel, which is the hard, calcium-rich material that forms the protective outer layer of each tooth. Mutations in any of these genes alter the structure of these proteins or prevent the genes from making any protein at all. As a result, tooth enamel is abnormally thin or soft and may have a yellow or brown color. Teeth with defective enamel are weak and easily damaged. In some cases, the genetic cause of amelogenesis imperfecta can not been identified. Researchers are working to find mutations in other genes that are responsible for this disorder. Click on each gene name to learn more about the role it plays in the development of tooth enamel.

What causes Amelogenesis imperfecta ?

Amelogenesis imperfecta can have different patterns of inheritance, depending on the gene that is altered. Most cases are caused by mutations in the ENAM gene and are inherited in an autosomal dominant pattern. This type of inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Amelogenesis imperfecta may also be inherited in an autosomal recessive pattern; this form of the disorder can result from mutations in the ENAM or MMP20 gene. Autosomal recessive inheritance means two copies of the gene in each cell are altered. About 5 percent of amelogenesis imperfecta cases are caused by mutations in the AMELX gene and are inherited in an X-linked pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. In most cases, males with X-linked amelogenesis imperfecta experience more severe dental abnormalities than females with this form of this condition. Other cases of amelogenesis imperfecta result from new mutations in these genes and occur in people with no history of the disorder in their family.

Is Amelogenesis imperfecta inherited ?

A dentist can identify and diagnose amelogenesis imperfecta on the basis of the patients family history and the signs and symptoms present in the affected individual. Extraoral X-rays (X-rays taken outside the mouth) can reveal the presence of teeth that never erupted o that were absorbed. Intraoral X-rays (X-rays taken inside the mouth) show contrast between the enamel and dentin in cases in which mineralization is affected. Genetic testing is available for the genes AMELX, ENAM, and MMP20. You can visit the Genetic Testing Registry to locate laboratories performing genetic testing for these genes. The American Academy of Pediatric Dentistry is a source of information to find a pediatric dentist. The National Dental Association can also assist people in locating a dentist.

How to diagnose Amelogenesis imperfecta ?

Treatment depends on the type of amelogenesis imperfecta and the type of enamel abnormality. Treatments include preventative measures, various types of crowns, as well as tooth implants or dentures in the most severe cases. The social and emotional impact of this condition should also be addressed. Detailed information on the treatment of amelogenesis imperfecta is available from the UNC School of Dentistry.

Adrenal insufficiency is an endocrine disorder that occurs when the adrenal glands do not produce enough of certain hormones. Secondary adrenal insufficiency occurs when the pituitary gland (a pea-sized gland at the base of the brain) fails to produce enough adrenocorticotropin (ACTH), a hormone that stimulates the adrenal glands to produce the hormone cortisol. The lack of these hormones in the body can be caused by reduction or cessation of corticosteroid medication, the surgical removal of pituitary tumors, or changes in the pituitary gland. Symptoms of secondary adrenal insufficiency may include severe fatigue, loss of appetite, weight loss, nausea, vomiting, diarrhea, muscle weakness, irritability, and depression. Treatment includes replacing the hormones that the adrenal glands are not making. The dose of each medication is adjusted to meet the needs of each affected individual.

Potocki-Shaffer syndrome is a contiguous gene deletion syndrome associated with deletions in a specific region of chromosome 11 (11p11. 2). The characteristic features of Potocki-Shaffer syndrome include openings in the two bones that form the top and sides of the skull (enlarged parietal foramina), multiple benign bone tumors called exostoses, intellectual disability, developmental delay, a distinctive facial appearance, autism and problems with vision and hearing. In some cases, individuals with the syndrome may have a defect in the heart, kidneys, or urinary tract. The features of Potocki-Shaffer syndrome result from the loss of several genes on the short (p) arm of chromosome 11. In particular, the deletion of a gene called ALX4 causes enlarged parietal foramina, while the loss of another gene, EXT2, causes the multiple exostoses. Another condition called WAGR syndrome is caused by a deletion of genetic material in the p arm of chromosome 11, specifically at position 11p13. Occasionally, a deletion is large enough to include the 11p11. 2 and 11p13 regions. Individuals with such a deletion have signs and symptoms of both Potocki-Shaffer syndrome and WAGR syndrome. A referral to an early childhood intervention and developmental-behavioral specialist at the time of diagnosis and to have an evaluation for vision and hearing problems, as well as a full skeletal survey at the time of diagnosis or by age 3 years, whichever is later, is recommended.

The treatment depends on the signs and symptoms present in the affected individual. The following treatment options or recommendations might be offered: Treatment of Wilms tumor, which may include surgery to remove the kidney, radiation therapy and chemotherapy. Treatment of aniridia is aimed at maintaining vision. Glaucoma or cataracts can be treated with medication or surgery. Contact lenses should be avoided because they can damage the cornea. In cases of abnormalities in the testes or ovaries, surgery may be needed to remove them or to prevent cancer (gonadoblastoma). After they testes or ovaries are removed hormone replacement is needed. Children with undescended testicles (cryptorchidism) may also need surgery. In a study with 6 patients and a review of 31 previously reported cases of Potocki-Shaffer syndrome, the researchers made several recommendations for the care of children with the syndrome. These include: Referral to early childhood intervention and a developmental-behavioral specialist at the time of diagnosis; A full skeletal survey at diagnosis or by age three; Screening for strabismus and nystagmus by the pediatrician (at every well-child examination), and referral to a pediatric ophthalmologist at diagnosis or by age six months; Hearing loss evaluations in infants with the syndrome and after that at three months of age; audiogram at age one year and annually thereafter; Fluorescence in situ hybridization (FISH) studies and genetic counseling should be offered to the parents of a child with Potocki-Shaffer syndrome; Referral to a specialist in development and behavior at the time of diagnosis for vision therapy, physical, occupational and speech therapy; Abdominal and kidney ultrasound due to the possible risk of developing a Wilms tumor, especially in those individuals who have a deletion in the 11p13 region; Cardiac evaluation to detect any heart abnormalities; Thyroid hormone level measurements to detect the hypothyroidism; and MRI scans are recommended if the individual has seizures, microcephaly, or global developmental delay. Some individuals with Potocki-Shaffer syndrome, WAGR syndrome, and renal insufficiency may be treated with dialysis or kidney transplant.

Cockayne syndrome is a rare condition which causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay. This syndrome also includes failure to thrive in the newborn, microcephaly, and impaired nervous system development. Other symptoms may include hearing loss, tooth decay, and eye and bone abnormalities. Cockayne syndrome type 1 (type A) is sometimes called classic or moderate Cockayne syndrome and is diagnosed during early childhood. Cockayne syndrome type 2 (type B) is sometimes referred to as the severe or early-onset type. This more severe form presents with growth and developmental abnormalities at birth. The third type, Cockayne syndrome type 3 (type C) is a milder form of the disorder. Cockayne syndrome is caused by mutations in either the ERCC8 (CSA) or ERCC6 (CSB) genes and is inherited in an autosomal recessive pattern. The typical lifespan for individuals with Cockayne syndrome type 1 is ten to twenty years. Individuals with type 2 usually do not survive past childhood. Those with type 3 live into middle adulthood.

Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. The different types of the disorder can also be distinguished by the severity of their signs and symptoms. Mutations in at least nine genes cause the various types of osteopetrosis.
