What is (are) Ataxia telangiectasia ? | Ataxia telangiectasia (A-T) is rare condition that affects the nervous system, the immune system, and many other parts of the body. Signs and symptoms of the condition usually begin in early childhood, often before age 5. The condition is typically characterized by cerebellar ataxia (uncoordinated muscle movements), oculomotor apraxia, telangiectasias, choreoathetosis (uncontrollable movements of the limbs), a weakened immune system with frequent infections, and an increased risk of cancers such as leukemia and lymphoma. A-T is caused by changes (mutations) in the ATM gene and is inherited in an autosomal recessive manner. Treatment is supportive and based on the signs and symptoms present in each person. | |
What are the symptoms of Ataxia telangiectasia ? | What are the signs and symptoms of Ataxia telangiectasia? Ataxia-telangiectasia affects the nervous system, immune system, and other body systems. This disorder is characterized by progressive difficulty with coordinating movements (ataxia) beginning in early childhood, usually before age 5. Affected children typically develop difficulty walking, problems with balance and hand coordination, involuntary jerking movements (chorea), muscle twitches (myoclonus), and disturbances in nerve function (neuropathy). The movement problems typically cause people to require wheelchair assistance by adolescence. People with this disorder also have slurred speech and trouble moving their eyes to look side-to-side (oculomotor apraxia). Small clusters of enlarged blood vessels called telangiectases, which occur in the eyes and on the surface of the skin, are also characteristic of this condition. The Human Phenotype Ontology provides the following list of signs and symptoms for Ataxia telangiectasia. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What is (are) Periventricular heterotopia ? | Periventricular heterotopia is a condition in which the nerve cells (neurons) do not migrate properly during the early development of the fetal brain from about the 6th week to the 24th week of pregnancy. Affected people typically develop recurrent seizures (epilepsy) beginning in mid-adolescence. Intelligence is generally normal; however, some affected people may have mild intellectual disability, including difficulty with reading and/or spelling. Less common signs and symptoms include microcephaly, developmental delay, recurrent infections, and blood vessel abnormalities. Some cases are caused by changes (mutations) in the FLNA gene and are inherited in an X-linked dominant manner. Others are caused by mutations in the ARFGEF2 gene and are inherited in an autosomal recessive manner. Rarely, periventricular heterotopia is associated with duplication of genetic material on chromosome 5. Treatment is generally focused on managing recurrent seizures with medications. | |
What are the symptoms of Periventricular heterotopia ? | What are the signs and symptoms of periventricular nodular heterotopia? The condition is first noticed when seizures appear, often during the teenage years. The nodules around the ventricles are then typically discovered when magnetic resonance imaging (MRI) studies are done. Patients usually have normal intelligence, although some have mild intellectual disability. Difficulty with reading and spelling (dyslexia) has been reported in some girls with periventricular heterotopia. Less commonly, individuals with periventricular heterotopia may have more severe brain malformations, small head size (microcephaly), developmental delays, recurrent infections, blood vessel abnormalities, or other problems. In the X-linked form of periventricular nodular heterotopia, affected patients are mostly females because in males the symptoms are too serious and they die before birth. The following clinical features have been reported: seizure disorder, mental problems, heart anomalies, stomach immobility, strabismus, short fingers and dyslexia. Periventricular heterotopia may also occur in association with other conditions such as Ehlers-Danlos syndrome (Ehlers-Danlos with periventricular heterotopia) which results in extremely flexible joints, skin that stretches easily, and fragile blood vessels. In the autosomal recessive form of periventricular heterotopia the disorder is severe and may include microcephaly, severe developmental delay, and seizures beginning in infancy. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show any signs or symptoms of this condition. | |
How to diagnose Periventricular heterotopia ? | What are the recommended evaluations for patients diagnosed with periventricular nodular heterotopia? The following evaluations are recommended:[1823] Imaging exams of the brain to establish the diagnosis Evaluation by a neurologist Evaluation by a doctor specialized in epilepsy if seizures are present Psychiatric evaluation if necessary Magnetic resonance angiography (MRA) of the brain vessels, carotid arteries, and aorta because of the risk for stroke Evaluation by a cardiologist and either echocardiogram or a heart magnetic resonance imaging (MRI) because of the risk for aortic aneurysm Evaluation by a hematologist if findings suggest a bleeding diathesis. | |
What are the treatments for Periventricular heterotopia ? | How might periventricular nodular heterotopia be treated? Treatment of epilepsy generally follows principles for a seizure disorder caused by a known structural brain abnormality; carbamezipine is most often used, because most patients have focal seizures. However, antiepileptic drugs may be selected based on side effects, tolerability, and efficacy. It is recommended that patients with the X-linked form of the disease have studies evaluating the carotid artery and an abdominal ultrasound because of the risk for aortic or carotid dissection or other vascular anomalies.[1823] Treatment also include surgery for removal of the lesion and more recently, laser ablation guided with magnetic resonance. | |

What is (are) Huntington disease ? | Huntington disease (HD) is an inherited condition that causes progressive degeneration of neurons in the brain. Signs and symptoms usually develop between ages 35 to 44 years and may include uncontrolled movements, loss of intellectual abilities, and various emotional and psychiatric problems. People with HD usually live for about 15 to 20 years after the condition begins. It is caused by changes (mutations) in the HTT gene and is inherited in an autosomal dominant manner. Treatment is based on the symptoms present in each person and may include various medications. There is also a less common, early-onset form of HD which begins in childhood or adolescence. For more information on this form, please visit GARD's juvenile Huntington disease Web page. | |
What are the symptoms of Huntington disease ? | What are the signs and symptoms of Huntington disease? Huntington disease (HD) is a progressive disorder that causes motor, cognitive, and psychiatric signs and symptoms. On average, most people begin developing features of HD between ages 35 and 44.

What causes Huntington disease ? | What causes Huntington disease? Huntington disease (HD) is caused by a change (mutation) in the HTT gene. This gene gives instructions for making a protein called huntingtin. The exact function of this protein is unclear, but it appears to be important to nerve cells (neurons) in the brain. The HTT gene mutation that causes HD involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of three DNA building blocks that repeat multiple times in a row. The CAG segment in a normal HTT gene repeats about 10 to 35 times. In people with HD, it may repeat from 36 to over 120 times. People with 36 to 39 CAG repeats (an intermediate size) may or may not develop HD, while people with 40 or more repeats almost always develop HD. An increased number of CAG repeats leads to an abnormally long version of the huntingtin protein. The long protein is then cut into smaller, toxic pieces that end up sticking together and accumulating in neurons. This disrupts the function of the neurons, ultimately causing the features of HD. | |
Is Huntington disease inherited ? | How is Huntington disease inherited? Huntington disease (HD) is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one of the 2 copies of the HTT gene is enough to cause the condition. When a person with HD has children, each child has a 50% (1 in 2) chance to inherit the mutated gene and develop the condition. Most people with HD have an affected parent. The family history can sometimes appear negative for various reasons even though a parent carries, or carried, a mutation in the HTT gene. In rare cases, HD is caused by a new (de novo) mutation in the HTT gene, in which case the disease occurs for the first time in the affected person and is not inherited from a parent. As HD is passed through generations, the size of the mutation in the HTT gene (called a trinucleotide repeat) often increases. A longer repeat in the HTT gene may cause earlier onset of symptoms. This phenomenon is called anticipation. | |
How to diagnose Huntington disease ? | Is genetic testing available for Huntington disease? Yes. Testing of adults at risk for Huntington disease (HD) who have no symptoms of the disease is called predictive testing. Whether to have predictive testing requires careful thought, including pre-test and post-test genetic counseling. This is particularly important because there is currently no cure. Furthermore, predictive testing cannot accurately predict the age a person with an HD mutation will develop symptoms, the severity or type of symptoms they will experience, or the future rate of disease progression. A person may want to have predictive testing because they feel they need to know, or to make personal decisions involving having children, finances, and/or career planning. Other people decide they do not want to know whether they will develop HD. Testing is appropriate to consider in symptomatic people of any age in a family with a confirmed diagnosis of HD. However, testing of asymptomatic people younger than age 18 is not considered appropriate. A main reason is that it takes away the choice of whether the person wants to know, while there is no major benefit to knowing at that age. People who are interested in learning more about genetic testing for HD should speak with a genetics professional. How is Huntington disease diagnosed? A diagnosis of Huntington disease is typically suspected in people with characteristic signs and symptoms of the condition and a family history consistent with autosomal dominant inheritance. The diagnosis can then be confirmed with genetic testing that identifies a specific type of change (mutation) in the HTT gene. | |
What are the treatments for Huntington disease ? | How might Huntington disease be treated? Unfortunately, there is currently no cure for Huntington disease (HD). The current goal of treatment is to slow down the course of the disease and help affected people function for as long and as comfortably as possible. Current treatment strategies involve the use of various medications to treat specific symptoms such as abnormal movements and behaviors. Depression and suicide are more common among affected people, so caregivers should monitor for associated symptoms and seek help if necessary. As symptoms of the disease worsen, affected people need more assistance, supervision, and care. | |
What is (are) Vohwinkel syndrome ? | Vohwinkel syndrome is an inherited condition that affects the skin. People with the "classic form" generally have honeycomb-patterned calluses on the palms of the hands and the soles of the feet (palmoplantar keratoses); constricting bands of tissue on the fingers and toes which can cause amputation; starfish-shaped, thickened skin on the tops of the fingers and knees; and hearing loss. A "variant form" of Vohwinkel syndrome has also been identified which is characterized by ichthyosis in addition to the classic skin abnormalities and is not associated with hearing loss. Classic Vohwinkel syndrome is caused by changes (mutations) in the GJB2 gene and the variant form is caused by mutations in the LOR gene. Both are inherited in an autosomal dominant manner. Although there is currently no cure for the condition, treatments are available to alleviate symptoms. | |
What are the symptoms of Vohwinkel syndrome ? | What are the signs and symptoms of Vohwinkel syndrome?

What is (are) Uncombable hair syndrome ? | Uncombable hair syndrome (UHS) is a rare disorder of the hair shaft of the scalp. It usually is characterized by silvery-blond or straw-colored hair that is disorderly; stands out from the scalp; and cannot be combed flat. It may first become apparent from 3 months of age to 12 years of age. UHS is likely inherited in an autosomal dominant manner with reduced penetrance. A responsible gene has not yet been identified. The condition often spontaneously regresses in late childhood. | |
What are the symptoms of Uncombable hair syndrome ? | What are the signs and symptoms of Uncombable hair syndrome? Uncombable hair syndrome (UHS) may first become apparent any time between the ages of 3 months and 12 years. It only affects the scalp hair. The quantity of hair remains normal, but the hair often grows slowly. Over time the hair becomes progressively silvery-blond or straw-colored; dry and disordered (standing out and growing in different directions); and unmanageable to comb flat. In some cases, constant efforts to groom the hair lead to breakage, but increased fragility is not a constant feature of the condition. In later childhood, there is usually a considerable amount of spontaneous improvement. The Human Phenotype Ontology provides the following list of signs and symptoms for Uncombable hair syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

In these cases, the sign or symptom may be rare or common. | |
What causes Uncombable hair syndrome ? | What causes uncombable hair syndrome? The stiffness of the hair in uncombable hair syndrome (UHS) is likely due to the triangular shape of the hair shaft that is seen in cross section in affected people. It has been suggested that the condition may result from premature keratinization (development of keratin) of the inner root sheath, which forms the channel for the growing hair. The inner root sheath conforms in configuration to the abnormal outline of the hair shaft. It thus forms an irregular, rigid tube that then alters the shape of the emerging hair. While it is assumed that the condition is autosomal dominant and thus due to changes (mutations) in a gene, no responsible gene has been identified. | |
Is Uncombable hair syndrome inherited ? | Is uncombable hair syndrome inherited? Uncombable hair syndrome (UHS) is thought to be inherited in an autosomal dominant manner with reduced penetrance. Autosomal dominant 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. When a person with a mutation that causes an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit that mutation. Reduced penetrance means that not all people with a mutation in the responsible gene will have the condition. For this reason, conditions with reduced penetrance may appear to "skip a generation" or may appear to occur for the first time (or only once) in a family. While people with UHS often report a negative family history, the characteristic hair shaft abnormality seen in affected people can still be seen in unaffected family members by looking at their hair under a specific type of microscope. | |
How to diagnose Uncombable hair syndrome ? | How is uncombable hair syndrome diagnosed? A diagnosis of uncombable hair syndrome (UHS) is made by observing the characteristic symptoms of the condition, as well observing the hair shaft under a special microscope. When the individual hair strands are viewed under a microscope, the hair is either triangular or kidney-shaped on cross section, and has a canal-like longitudinal groove along one or two faces. People with concerns about symptoms of UHS are encouraged to speak with their dermatologist about being evaluated for this condition. | |
What are the treatments for Uncombable hair syndrome ? | How might uncombable hair syndrome be treated? There is no definitive treatment for uncombable hair syndrome, but the condition usually improves or resolves on its own with the onset of puberty. Gentle hair care is generally recommended using conditioners and soft brushes, along with avoiding harsh hair treatments such as permanent waves (perms); chemical relaxants; or excessive brushing and blow drying. These strategies may improve the general manageability of the hair, although how well they work is subjective. Another strategy that has been suggested to improve the appearance of the hair is the use of biotin supplements. One case report suggested significant improvement in hair strength and combability, with an increase in rate of growth after 4 months of supplementation. | |

What is (are) Cleidocranial dysplasia ? | Cleidocranial dysplasia is a condition that primarily affects the development of the bones and teeth. Characteristic features of this condition include underdeveloped or absent collarbones (clavicles) and delayed closing of the spaces between the bones of the skull (fontanels). Individuals with cleidocranial dysplasia may also have decreased bone density (osteopenia), osteoporosis, dental abnormalities, hearing loss, and recurrent sinus and ear infections. Mutations in the RUNX2 gene cause most cases of cleidocranial dysplasia. This condition is inherited in an autosomal dominant pattern. In some cases, a person inherits cleidocranial dysplasia from a parent who also has the condition. Other cases result from new mutations (de novo mutations) in the RUNX2 gene. Dental problems are addressed with several procedures. Ear and sinus infections may be treated with antibiotics and use of ear tubes. In some cases surgery is needed for the cranial defect. | |

What causes Cleidocranial dysplasia ? | What causes cleidocranial dysplasia? Cleidocranial dysplasia is caused by mutations in the RUNX2 (CBFA1) gene. The RUNX2 gene provides instructions for making a protein that is involved in bone and cartilage development and maintenance. Researchers believe that the RUNX2 protein acts as a "master switch," regulating a number of other genes involved in the development of cells that build bones (osteoblasts). Some mutations change one protein building block (amino acid) in the RUNX2 protein. Other mutations result in an abnormally short protein. This shortage of functional RUNX2 protein interferes with normal bone and cartilage development, resulting in the signs and symptoms of cleidocranial dysplasia. In rare cases, affected individuals may experience additional, unusual symptoms resulting from the loss of other genes located near RUNX2. In about one-third of individuals with cleidocranial dysplasia, no mutation in the RUNX2 gene has been found. The cause of the condition in these individuals is unknown. Read more about the RUNX2 gene. | |
Is Cleidocranial dysplasia inherited ? | How is cleidocranial dysplasia inherited? Cleidocranial dysplasia is inherited in an autosomal dominant manner, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits the mutation from one affected parent. Other cases may result from de novo mutations (new mutations) in the gene. These cases occur in people with no history of the disorder in their family. | |
What are the treatments for Cleidocranial dysplasia ? | What treatment is available for cleidocranial dysplasia? Because there is no specific treatment for cleidocranial dysplasia, treatment is based on an individual's symptoms. Affected individuals typically require dental care due to various teeth abnormalities. People with cleidocranial dysplasia may receive supplements of calcium and vitamin D if their bone density is below normal, and preventive treatment for osteoporosis is usually started at a young age. Some affected individuals may need ear tubes if they have frequent ear infections. If the cranial vault defect is serious, it is important to protect the head wearing helmets during high-risk activities. Surgery may be needed to correct a depressed forehead or for the enlargement of small clavicles. | |
What is (are) Dentatorubral-pallidoluysian atrophy ? | Dentatorubral-pallidoluysian atrophy (DRPLA) is a progressive brain disorder that causes involuntary movements; mental and emotional problems; and a decline in thinking ability. The average age of onset of DRPLA is 30 years, but the condition can appear anytime from infancy to mid-adulthood. Specific signs and symptoms may differ among affected individuals and sometimes affects children and adults differently. DRPLA is caused by a mutation in the ATN1 gene and is inherited in an autosomal dominant manner. Treatment is symptomatic and supportive. | |
What are the symptoms of Dentatorubral-pallidoluysian atrophy ? | What are the signs and symptoms of Dentatorubral-pallidoluysian atrophy? The signs and symptoms of DRPLA differ somewhat between affected children and adults. When DRPLA appears before age 20, it most often involves episodes of involuntary muscle jerking or twitching (myoclonus); seizures; behavioral changes; intellectual disability; and problems with balance and coordination (ataxia). Epileptic seizures occur in all individuals with onset before 20 years of age. When DRPLA begins after age 20, the most frequent signs and symptoms are ataxia; uncontrollable movements of the limbs (choreoathetosis); psychiatric symptoms such as delusions; and deterioration of intellectual function (dementia). Seizures are less frequent in individuals with onset between the ages of 20 and 40. Seizures are rare in individuals with onset after age 40. Individuals who have inherited the condition from an affected parent typically have symptoms 26 to 29 years earlier than affected fathers, and 14 to 15 years earlier than affected mothers.

What causes Dentatorubral-pallidoluysian atrophy ? | What causes dentatorubral-pallidoluysian atrophy (DRPLA)? DRPLA is caused by a mutation in the ATN1 gene. This gene provides instructions for making a protein called atrophin 1. Although the function of atrophin 1 is unclear, it likely plays an important role in nerve cells (neurons) in many areas of the brain. The ATN1 mutation that causes DRPLA involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row on the gene. Normally, this CAG segment is repeated 6 to 35 times within the ATN1 gene. In people with DRPLA, the CAG segment is repeated at least 48 times (and sometimes much more). The abnormally long CAG trinucleotide repeat changes the structure of the atrophin 1 protein, which then accumulates in neurons and interferes with normal cell functions. The dysfunction and eventual death of these neurons lead to the signs and symptoms associated with DRPLA. | |

What is (are) Laryngomalacia ? | Laryngomalacia is an abnormality of the cartilage of the voice box (larynx) that is present at birth. The condition is characterized by "floppy" cartilage collapsing over the larynx when air is drawn into the lungs (inspiration), leading to airway obstruction. This obstruction causes a noise which may sound like nasal congestion or may be a more high-pitched sound (stridor). Airway sounds typically begin at 4-6 weeks of age. Affected infants have a higher risk of gastroesophageal reflux, and in severe cases may have feeding problems. In rare cases, hypoxemia or hypoventilation may interfere with normal growth and development. The cause of this condition is unknown, but it is thought to be due to delayed maturation of the supporting structures of the larynx. In more than 90% of cases it gradually improves on its own, and noises disappear by age 2 in virtually all infants. | |

Is Laryngomalacia inherited ? | Is laryngomalacia inherited? Laryngomalacia may be inherited in some instances. Only a few cases of familial laryngomalacia (occurring in more than one family member) have been described in the literature. In some of these cases, autosomal dominant inheritance has been suggested. Laryngomalacia has also been reported as being associated with various syndromes. In cases where these specific syndromes are inherited, a predisposition to being born with laryngomalacia may be present. However, even within a family, not all individuals affected with one of these syndromes will have the exact same signs and symptoms (including laryngomalacia). Syndromes that have been associated with laryngomalacia include diastrophic dysplasia, alopecia universalis congenital, XY gonadal dysgenesis, Costello syndrome, DiGeorge syndrome, and acrocallosal syndrome. The inheritance pattern depends upon the specific syndrome present. | |
What is (are) Erythropoietic protoporphyria ? | Erythropoietic protoporphyria is a type of porphyria. Porphyrias are caused by an abnormality in the heme production process. Heme is essential in enabling our blood cells to carry oxygen and in breaking down chemical compounds in the liver. Erythropoietic protoporphyria is caused by impaired activity of ferrocheletase (FECH), an important enzyme in heme production. This results in the build-up of protoporphyrin in the bone marrow, red blood cells, blood plasma, skin, and eventually liver. Build up of protoporphyrin can cause extreme sensitivity to sunlight, liver damage, abdominal pain, gallstones, and enlargement of the spleen. | |

What causes Erythropoietic protoporphyria ? | What is the genetic basis of erythropoietic protoporphyria? Erythropoietic protoporphyria is caused by mutations in the FECH gene. | |
Is Erythropoietic protoporphyria inherited ? | How is erythropoietic protoporphyria (EPP) inherited? EPP is inherited in an autosomal recessive manner. In most cases, affected individuals have one severe (loss-of-function) mutation that is inherited from one parent, and another weak (low-expression) mutation that is inherited from the other parent. In a small number of cases, an affected individual has two loss-of-function mutations. When 2 carriers of an autosomal recessive condition have children, each child has a: 25% (1 in 4) chance to be affected 50% (1 in 2) chance to be an unaffected carrier like each parent 25% (1 in 4) chance to be unaffected and not be a carrier | |
What is (are) Fetal hydantoin syndrome ? | Fetal hydantoin syndrome is a disorder that is caused by exposure of a fetus to phenytoin, a drug commonly prescribed for epilepsy. Not all infants exposed to phenytoin will be affected with the disorder. Symptoms in affected individuals may include abnormalities of the skull and facial features, growth deficiencies, underdeveloped nails of the fingers and toes, and/or mild developmental delays. Other findings occasionally associated with this syndrome include cleft lip and palate, having an abnormally small head (microcephaly) and brain malformations with more significant developmental delays. Treatment may include surgery for cleft lip and palate and special education and related services for children with learning delays. Other treatment is symptomatic and supportive. | |
What are the symptoms of Fetal hydantoin syndrome ? | What are the signs and symptoms of Fetal hydantoin syndrome? There is a wide range in the nature and severity of characteristics associated with fetal hydantoin syndrome. Of infants born to women who used phenytoin during pregnancy, 10-30% are reported to show some of the characteristics associated with this syndrome. Few infants exposed only to phenytoin have all of the characteristic that have been reported. Children with this condition may be small at birth, with increased hair on the body and face, and with poorly developed fingernails and toenails. They may also have poor muscle tone. Facial features that may be present with this syndrome include a flat bridge of the nose; an underdeveloped vertical groove in the center of the upper lip (philtrum); a large mouth; and malformed ears. Features specific to the eyes may include down-slanted eyes; widely spaced eyes (hypertelorism); crossed eyes (strabismus); drooping eyelids (ptosis); and/or epicanthal folds (skin folds of the eyelid covering the inner corner of the eye). Other features that have been reported include a short or webbed neck and low-set hair line. Growth deficiencies may include underdeveloped fingers and/or toes, malformed nails, as well as finger-like thumbs. These features are often associated with growth delay and varying degrees of developmental delay. The risk for an affected child to be neurologically impaired is estimated at 1 to 11 % (two to three times higher than for the general population). The risk of cleft lip and/or palate and heart defects is estimated to be about five times higher among exposed infants. Some case reports have suggested an increased risk for the occurrence of benign (noncancerous) or malignant (cancerous) tumors, such as neuroblastoma or other neonatal tumors (ependymoma, ectodermal tumors, Wilms tumor). The Human Phenotype Ontology provides the following list of signs and symptoms for Fetal hydantoin syndrome.

For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. | |
What is (are) Maternally inherited diabetes and deafness ? | Maternally inherited diabetes and deafness (MIDD) is a form of diabetes that is often accompanied by hearing loss, especially of high tones. The diabetes in MIDD is characterized by high blood sugar levels (hyperglycemia) resulting from a shortage of the hormone insulin, which regulates the amount of sugar in the blood. MIDD is caused by mutations in the MT-TL1, MT-TK, or MT-TE gene. These genes are found in mitochondrial DNA, which is part of cellular structures called mitochondria. Although most DNA is packaged in chromosomes within the cell nucleus, mitochondria also have a small amount of their own DNA (known as mitochondrial DNA or mtDNA). Because the genes involved with MIDD are found in mitochondrial DNA, this condition is inherited in a mitochondrial pattern, which is also known as maternal inheritance. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, only females pass mitochondrial conditions to their children. Mitochondrial disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass mitochondrial traits to their children. | |

In these cases, the sign or symptom may be rare or common. When do the diabetes and hearing loss associated with MIDD typically develop? In MIDD, the diabetes and hearing loss usually develop in mid-adulthood, although the age that they occur varies from childhood to late adulthood. Typically, hearing loss occurs before diabetes. | |
Is Maternally inherited diabetes and deafness inherited ? | How do people inherit MIDD? MIDD is inherited in a mitochondrial pattern, which is also known as maternal inheritance. This pattern of inheritance applies to genes contained in mitochondrial DNA. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, only females pass mitochondrial conditions to their children. Mitochondrial disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass mitochondrial traits to their children. Most of the body's cells contain thousands of mitochondria, each with one or more copies of mitochondrial DNA. These cells can have a mix of mitochondria containing mutated and unmutated DNA (heteroplasmy). The severity of MIDD is thought to be associated with the percentage of mitochondria with the mitochondrial DNA mutation. | |

What is (are) 46,XX testicular disorder of sex development ? | 46,XX testicular disorder of sex development is a condition in which a person with two X chromosomes (which is normally found in females) has a male appearance. More specifically, people with this condition have male external genitalia, ranging from normal to ambiguous. Other common signs and symptoms include small testes, gynecomastia, infertility due to azoospermia (lack of sperm), and health problems related to low testosterone. Less often, affected people may experience abnormalities such as undescended testes and hypospadias. Gender role and gender identity are normally reported as male. This condition may occur if the SRY gene (which is usually found on the Y chromosome) is misplaced onto the X chromosome. This generally occurs to do an abnormal exchange of genetic material between chromosomes (a translocation). Less commonly, the condition may be due to copy number variants or rearrangements in or around the SOX9 or SOX3 gene. In some affected people, the underlying cause is unknown. In most cases, the condition occurs sporadically in people with no family history of the condition. Treatment is based on the signs and symptoms present in each person and generally includes testosterone replacement therapy. | |

What is (are) Pulmonary arterial hypertension ? | Pulmonary arterial hypertension (PAH) is a progressive condition that affects the heart and lungs. It is characterized by abnormally high blood pressure (hypertension) in the pulmonary artery, the blood vessel that carries blood from the heart to the lungs. The most common signs and symptoms are shortness of breath (dyspnea) during exertion and fainting spells. As the condition worsens, people can experience dizziness, swelling (edema) of the ankles or legs, chest pain, and a racing pulse. Most cases of PAH occur in individuals with no family history of the disorder. Although some cases are due to mutations in the BMPR2 gene and inherited in an autosomal dominant pattern, a gene mutation has not yet been identified in most individuals. When PAH is inherited from an affected relative it is called "familial" PAH. Cases with no identifiable cause may be referred to as "idiopathic" PAH. PAH can also occur secondary to an underlying disorder such as connective tissue diseases, HIV infection, chronic hemolytic anemia, and congenital heart disease, to name a few. PAH can also be induced by certain drugs and toxins, for example fenfluramine and dexfenfluramine (appetite suppressants now banned by the FDA), toxic rapeseed oil, and amphetamines. | |

What are the treatments for Pulmonary arterial hypertension ? | How might pulmonary arterial hypertension be treated? People with pulmonary arterial hypertension (PAH) benefit from receiving treatment at specialized centers. The Pulmonary Hypertension Association offers a Find a Doctor tool which may aid you in locating your nearest center. Treatment of serious or life threatening PAH may involve continuous IV epoprostenol. Other treatment options, include treprostinil, iloprost, bosentan, ambrisentan, sildenafil, and tadalafil. Many of these treatments can be administered in various forms, such as by shot, IV, or inhalation. A small number of people with PAH respond well to long term oral calcium channel blockers. Blood thinners, diuretics, and supplemental oxygen may be prescribed as needed. Many drugs can be harmful to people with PAH. The following should be avoided: appetite suppressants, cocaine, amphetamines (and related compounds), low oxygen environments (such as high altitudes), and possibly estrogen compounds (oral contraceptives and hormone replacement therapy). | |

What is (are) Dowling-Degos disease ? | Dowling-Degos disease is a skin condition characterized by a lacy or net-like (reticulate) pattern of abnormally dark skin coloring (hyperpigmentation), particularly in the body's folds and creases. Other features may include dark lesions on the face and back that resemble blackheads, red bumps around the mouth that resemble acne, depressed or pitted scars on the face similar to acne scars but with no history of acne, cysts within hair follicles (pilar cysts) on the scalp, and rarely, patches of skin that are unusually light in color (hypopigmented). Symptoms typically develop in late childhood or in adolescence and progress over time. While the skin changes caused by Dowling-Degos disease can be bothersome, they typically don't cause health problems. Dowling-Degos disease is caused by mutations in the KRT5 gene. This condition is inherited in an autosomal dominant pattern. | |
What are the symptoms of Dowling-Degos disease ? | What are the signs and symptoms of Dowling-Degos disease? Dowling-Degos disease is characterized by a lacy or net-like (reticulate) pattern of abnormally dark skin coloring (hyperpigmentation), particularly in the body's folds and creases. These skin changes typically first appear in the armpits and groin area and can later spread to other skin folds such as the crook of the elbow and back of the knee. Less commonly, pigmentation changes can also occur on the wrist, back of the hand, face, scalp, scrotum (in males), and vulva (in females). These areas of hyperpigmentation are not affected by exposure to sunlight. Individuals with Dowling-Degos disease may also have dark lesions on the face and back that resemble blackheads, red bumps around the mouth that resemble acne, or depressed or pitted scars on the face similar to acne scars but with no history of acne. Cysts within the hair follicle (pilar cysts) may develop, most commonly on the scalp. Rarely, affected individuals have patches of skin that are unusually light in color (hypopigmented). The pigmentation changes characteristic of Dowling-Degos disease typically begin in late childhood or in adolescence, although in some individuals, features of the condition do not appear until adulthood. New areas of hyperpigmentation tend to develop over time, and the other skin lesions tend to increase in number as well. While the skin changes caused by Dowling-Degos disease can be bothersome, they typically cause no health problems. The Human Phenotype Ontology provides the following list of signs and symptoms for Dowling-Degos disease. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What are the treatments for Dowling-Degos disease ? | Is there a medicine that can cure Dowling-Degos disease? There is no cure for Dowling-Degos disease. Many different treatments have been tried for this condition, but none has proven effective in eliminating the symptoms for all patients. Topical retinoic acids, topical steroids, hydroquinone, tretinoin, and systemic retinoids have been used without success. Limited reports indicate at least temporary therapeutic benefit with topical adapalene. Various laser systems (CO2 and erbiumYAG) have also shown some promise. Additional articles that address this topic can be accessed below: Altomare G, Capella GL, Fracchiolla C, Frigerio E. Effectiveness of topical adapalene in Dowling-Degos disease.

What is (are) Glycogen storage disease type 7 ? | Glycogen storage disease type 7 (GSD7) is an inherited condition in which the body is unable to break down glycogen (a complex sugar) in the muscle cells. Because glycogen is an important source of energy, this can interfere with the normal functioning of muscle cells. The severity of the condition and the associated signs and symptoms vary, but may include muscle weakness and stiffness; painful muscle cramps; nausea and vomiting; and/or myoglobinuria (the presence of myoglobin in the urine) following moderate to strenuous exercise. Symptoms typically resolve with rest. GSD7 is most commonly diagnosed during childhood; however, some affected people may rarely develop symptoms during infancy or later in adulthood. Those who develop the condition during infancy may experience additional symptoms such as hypotonia (poor muscle tone), cardiomyopathy and breathing difficulties that often lead to a shortened lifespan (less than 1 year). This condition is caused by changes (mutations) in the PFKM gene and is inherited in an autosomal recessive manner. There is no specific treatment for GSD7; however, affected people are generally advised to avoid vigorous exercise and high-carbohydrate meals. | |

What is (are) Blepharophimosis, ptosis, and epicanthus inversus syndrome type 2 ? | Blepharophimosis, ptosis, and epicanthus inversus syndrome type 2 (BPES II) is a condition that mainly affects the development of the eyelids. People with this condition have a narrowing of the eye opening (blepharophimosis), droopy eyelids (ptosis), and an upward fold of the skin of the lower eyelid near the inner corner of the eye (epicanthus inversus). In addition, there is an increased distance between the inner corners of the eyes (telecanthus). Because of these eyelid malformations, the eyelids cannot open fully, and vision may be limited. BPES type 2 consists only of the eyelid malformations, whereas BPES type 1 also causes premature ovarian failure. It is caused by mutations in the FOXL2 gene and is inherited in an autosomal dominant manner. Treatment typically consists of various eyelid surgeries to correct the malformations. | |

What is (are) PURA syndrome ? | PURA syndrome is a neurodevelopmental disorder characterized by mild to moderate developmental delay, learning disability, seizures and seizure-like movements, low muscle tone (hypotonia), feeding difficulties, and breathing problems. PURA syndrome occurs when one of a person's two copies of the PURA gene, located on chromosome 5, does not function normally. The reason for this is unknown. Because the features of PURA syndrome are common, a genetic test (such as whole genome sequencing) is needed for diagnosis. Treatment typically includes speech and language support as well as physical and occupational therapy. Early intervention is key. | |
What is (are) Papillary renal cell carcinoma ? | Papillary renal cell carcinoma (PRCC) is a type of cancer that occurs in the kidneys. It accounts for about 10-15% of all renal cell carcinomas.Renal cell carcinomas are a type of kidney cancer that develop in the lining of very small tubes (tubules) in the kidney.The term "papillary" describes the finger-like projections that can be found in most of the tumors. PRCC can be divided into two types: type 1, which is more common and usually grows more slowly and type 2, which are usually more aggressive .Though the exact cause of papillary renal cell carcinoma is unknown, smoking, obesity, and genetic predisposition conditions (such as hereditary leiomyomatosis and renal cell cancer) may contribute to the development of this type of cancer. Treatment often begins with surgery to remove as much of the cancer as possible, and may be followed by radiation therapy, chemotherapy, biological therapy, or targeted therapy. | |

What is (are) Glass-Chapman-Hockley syndrome ? | The Glass-Chapman-Hockley syndrome is a very rare disease. To date, the syndrome has only been reported in one family with five members affected in three generations. The first patients were two brothers that had an abnormally-shaped head due to coronal craniosynostosis. Their mother, maternal aunt, and maternal grandmother were also found to have the syndrome. The signs and symptoms varied from person to person; however, the signs and symptoms included coronal craniosynostosis, small middle part of the face (midfacial hypoplasia), and short fingers (brachydactyly). The inheritance is thought to be autosomal dominant. No genes have been identified for this syndrome. Treatment included surgery to correct the craniosynostosis. No issues with development and normal intelligence were reported. | |

What are the treatments for Glass-Chapman-Hockley syndrome ? | How might Glass-Chapman-Hockley syndrome be treated? Surgery is typically the treatment for craniosynostosis and is based on the person's specific signs and symptoms. The goal is to increase the space in the front (anterior) part of the skull. The operation is usually performed when the person is between 9 to 12 months of age. If other sutures, other than the coronal suture, are involved, other surgeries may be performed. | |
What is (are) Agenesis of the dorsal pancreas ? | Agenesis of the dorsal pancreas describes a congenital malformation of the pancreas in which either the entire dorsal pancreas or part of the dorsal pancreas fails to develop (complete agenesis or partial agenesis, respectively). Some individuals experience no symptoms, while others may develop hyperglycemia, diabetes mellitus, bile duct obstruction, abdominal pain, pancreatitis, or other conditions. Hyperglycemia has been shown to be present in approximately 50% of affected individuals. The cause of agenesis of the dorsal pancreas is currently not well understood. It may occur in individuals with no history of the condition in the family (sporadically) and in some cases, autosomal dominant or X-linked dominant inheritance has been suggested. It has also been reported to occur with very rare conditions including polysplenia and polysplenia/heterotaxy syndrome. | |

What causes Agenesis of the dorsal pancreas ? | What causes agenesis of the dorsal pancreas? Partial or complete agenesis of the dorsal pancreas results from the failure of the dorsal pancreatic bud to form the body and tail of the pancreas in the developing fetus. It may occur from the absence, or regression of, the dorsal bud during fetal development. Heredity may play a role in the development of this condition, but further research is needed to clarify this. There have been reports in the literature of the condition being associated (rarely) with other congenital diseases, specifically a very rare disorder called polysplenia/heterotaxy syndrome. In this case, it may occur due to errors in development of the asymmetric organs and may be associated with benign to severe congenital cardiac (heart) malformations. | |
What are the treatments for Agenesis of the dorsal pancreas ? | How might agenesis of the dorsal pancreas be treated? Because agenesis of the dorsal pancreas is considered rare and few cases have been reported in the literature, there is limited information about how the condition as a whole might be treated or managed. However, there is current information about how some of the signs and symptoms associated with agenesis of the dorsal pancreas (such as pancreatitis) may be managed. For pancreatitis, individuals may be able to make themselves more comfortable during an attack, but they will most likely continue to have attacks until treatment is received for the underlying cause of the symptoms (when possible). If symptoms are mild, people might try the following preventive measures: stopping all alcohol consumption; adopting a liquid diet consisting of foods such as broth, gelatin, and soups (these simple foods may allow the inflammation process to get better); over-the-counter pain medications; and avoiding pain medications that can affect the liver (such as acetaminophen). Medical treatment is usually focused on relieving symptoms and preventing further aggravation to the pancreas. Certain complications of either acute pancreatitis or chronic pancreatitis may require surgery or a blood transfusion. In acute pancreatitis, the choice of treatment is based on the severity of the attack. Most people who are having an attack of acute pancreatitis are admitted to the hospital for oxygen (if having trouble breathing) and an intravenous (IV) line for medications and fluids. If needed, medications for pain and nausea may be prescribed. It may be recommended that no food or liquid is taken by mouth for a few days (this is called bowel rest). Some people may need a nasogastric (NG) tube to remove stomach juices which rests the intestine further, helping the pancreas recover. If the attack lasts longer than a few days, nutritional supplements may be administered through an IV line. In chronic pancreatitis, treatment focuses on relieving pain and avoiding further aggravation to the pancreas. Hyperglycemia (high blood sugar) management may depend on the exact cause if the condition in the affected individual. Management may include checking blood sugar levels with a blood glucose meter; checking urine for ketones; and adopting strategies to lower blood sugar level. Strategies might include exercise (only if urine ketones are not present); diet as discussed with a diabetes health educator or registered dietitian; and/or medication (especially if diet and exercise are not keeping blood sugar levels in the normal range) which may include insulin and/or other medications. Individuals seeking treatment options for themselves or others should speak with their health care provider about an individualized treatment plan; the information here is provided for general educational purposes only. | |
What is (are) Familial hyperinsulinism ? | Familial hyperinsulinism is an inherited condition that causes individuals to have abnormally high levels of insulin, which leads to frequent episodes of low blood sugar (hypoglycemia). In infants and young children, these episodes are characterized by a lack of energy (lethargy), irritability, and/or difficulty feeding. Repeated episodes of low blood sugar increase the risk for serious complications such as seizures, intellectual disability, breathing difficulties, and/or coma. Unlike typical episodes of hypoglycemia, which occur after periods without food (fasting), episodes of hypoglycemia in people with familial hyperinsulinism can also occur after eating or exercising. Mutations in at least seven genes have been found to cause this condition. It is often inherited in an autosomal recessive pattern or less commonly, an autosomal dominant pattern. | |

What is (are) Sacrococcygeal Teratoma ? | A sacrococcygeal teratoma is a tumor that grows at the base of the spine in a developing fetus. It occurs in one in 40,000 newborns and girls are four times more likely to be affected than boys. Though it is usually benign, there is a possibility that the teratoma could become malignant. As such, the recommended treatment of a teratoma is complete removal of the tumor by surgery, performed soon after the birth. If not all of the tumor is removed during the initial surgery, the teratoma may grow back (recur) and additional surgeries may be needed. Studies have found that sacrococcygeal teratomas recur in up to 22% of cases. | |
What are the treatments for Sacrococcygeal Teratoma ? | How might a sacrococcygeal teratoma be treated? The treatment for sacrococcygeal teratoma (SCT) typically involves surgery to remove the tumor. Surgery occurs either in the prenatal period or shortly after delivery. The timing is dependent on the size of the tumor and the associated symptoms.

Signs and Symptoms Approximate number of patients (when available) Autosomal dominant inheritance - Duodenal ulcer - Hyperpepsinogenemia I - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common. |
