Topic: ADCY5-related dyskinesia
Question: What is (are) ADCY5-related dyskinesia ?
Answer: ADCY5-related dyskinesia is a movement disorder; the term "dyskinesia" refers to abnormal involuntary movements. The abnormal movements that occur in ADCY5-related dyskinesia typically appear as sudden (paroxysmal) jerks, twitches, tremors, muscle tensing (dystonia), or writhing (choreiform) movements, and can affect the limbs, neck, and face.  The abnormal movements associated with ADCY5-related dyskinesia usually begin between infancy and late adolescence. They can occur continually during waking hours and in some cases also during sleep. Severely affected infants may experience weak muscle tone (hypotonia) and delay in development of motor skills such as crawling and walking; these individuals may have difficulties with activities of daily living and may eventually require a wheelchair. In more mildly affected individuals, the condition has little impact on walking and other motor skills, although the abnormal movements can lead to clumsiness or difficulty with social acceptance in school or other situations.  In some people with ADCY5-related dyskinesia, the disorder is generally stable throughout their lifetime. In others, it slowly gets worse (progresses) in both frequency and severity before stabilizing or even improving in middle age. Anxiety, fatigue, and other stress can temporarily increase the severity of the signs and symptoms of ADCY5-related dyskinesia, while some affected individuals may experience remission periods of days or weeks without abnormal movements. Life expectancy and intelligence are unaffected by this disorder.

Topic: ADCY5-related dyskinesia
Question: What are the genetic changes related to ADCY5-related dyskinesia ?
Answer: As its name suggests, ADCY5-related dyskinesia is caused by mutations in the ADCY5 gene. This gene provides instructions for making an enzyme called adenylate cyclase 5. This enzyme helps convert a molecule called adenosine triphosphate (ATP) to another molecule called cyclic adenosine monophosphate (cAMP). ATP is a molecule that supplies energy for cells' activities, including muscle contraction, and cAMP is involved in signaling for many cellular functions. Some ADCY5 gene mutations that cause ADCY5-related dyskinesia are thought to increase adenylate cyclase 5 enzyme activity and the level of cAMP within cells. Others prevent production of adenylate cyclase 5. It is unclear how either type of mutation leads to the abnormal movements that occur in this disorder.

Topic: ADCY5-related dyskinesia
Question: Is ADCY5-related dyskinesia inherited ?
Answer: This condition is inherited in an autosomal dominant pattern, 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 result from new mutations in the gene and occur in people with no history of the disorder in their family.

Topic: alveolar capillary dysplasia with misalignment of pulmonary veins
Question: What is (are) alveolar capillary dysplasia with misalignment of pulmonary veins ?
Answer: Alveolar capillary dysplasia with misalignment of pulmonary veins (ACD/MPV) is a disorder affecting the development of the lungs and their blood vessels. The disorder affects the millions of small air sacs (alveoli) in the lungs and the tiny blood vessels (capillaries) in the alveoli. It is through these alveolar capillaries that inhaled oxygen enters the bloodstream for distribution throughout the body and carbon dioxide leaves the bloodstream to be exhaled.  In ACD/MPV, the alveolar capillaries fail to develop normally. The number of capillaries is drastically reduced, and existing capillaries are improperly positioned within the walls of the alveoli. These abnormalities in capillary number and location impede the exchange of oxygen and carbon dioxide.  Other abnormalities of the blood vessels in the lungs also occur in ACD/MPV. The veins that carry blood from the lungs into the heart (pulmonary veins) are improperly positioned and may be abnormally bundled together with arteries that carry blood from the heart to the lungs (pulmonary arteries). The muscle tissue in the walls of the pulmonary arteries may be overgrown, resulting in thicker artery walls and a narrower channel. These changes restrict normal blood flow, which causes high blood pressure in the pulmonary arteries (pulmonary hypertension) and requires the heart to pump harder.  Most infants with ACD/MPV are born with additional abnormalities. These may include abnormal twisting (malrotation) of the large intestine or other malformations of the gastrointestinal tract. Cardiovascular and genitourinary abnormalities are also common in affected individuals.  Infants with ACD/MPV typically develop respiratory distress within a few minutes to a few hours after birth. They experience shortness of breath and cyanosis, which is a bluish appearance of the skin, mucous membranes, or the area underneath the fingernails caused by a lack of oxygen in the blood. Without lung transplantation, infants with ACD/MPV have not been known to survive past one year of age, and most affected infants live only a few weeks.

Topic: alveolar capillary dysplasia with misalignment of pulmonary veins
Question: What are the genetic changes related to alveolar capillary dysplasia with misalignment of pulmonary veins ?
Answer: ACD/MPV can be caused by mutations in the FOXF1 gene. The protein produced from the FOXF1 gene is a transcription factor, which means that it attaches (binds) to specific regions of DNA and helps control the activity of many other genes. The FOXF1 protein is important in development of the lungs and their blood vessels. The FOXF1 protein is also involved in the development of the gastrointestinal tract. Mutations in the FOXF1 gene that cause ACD/MPV result in an inactive protein that cannot regulate development, leading to abnormal formation of the pulmonary blood vessels and gastrointestinal tract.  ACD/MPV can also be caused by a deletion of genetic material on the long arm of chromosome 16 in a region known as 16q24.1. This region includes several genes, including the FOXF1 gene. Deletion of one copy of the FOXF1 gene in each cell reduces the production of the FOXF1 protein. A shortage of FOXF1 protein affects the development of pulmonary blood vessels and causes the main features of ACD/MPV. Researchers suggest that the loss of other genes in this region probably causes the additional abnormalities, such as heart defects, seen in some infants with this disorder. Like FOXF1, these genes also provide instructions for making transcription factors that regulate development of various body systems before birth.  In about 60 percent of affected infants, the genetic cause of ACD/MPV is unknown.

Topic: alveolar capillary dysplasia with misalignment of pulmonary veins
Question: Is alveolar capillary dysplasia with misalignment of pulmonary veins inherited ?
Answer: ACD/MPV is usually not inherited, and most affected people have no history of the disorder in their family. The genetic changes associated with this condition usually occur during the formation of reproductive cells (eggs and sperm) or in early fetal development. When the condition is caused by a FOXF1 gene mutation or deletion, one altered or missing gene in each cell is sufficient to cause the disorder. Individuals with ACD/MPV do not pass the genetic change on to their children because they do not live long enough to reproduce.  A few families have been identified in which more than one sibling has ACD/MPV. It is not clear how ACD/MPV is inherited in these families because no genetic changes have been identified.

Topic: Bartter syndrome
Question: What is (are) Bartter syndrome ?
Answer: Bartter syndrome is a group of very similar kidney disorders that cause an imbalance of potassium, sodium, chloride, and related molecules in the body.  In some cases, Bartter syndrome becomes apparent before birth. The disorder can cause polyhydramnios, which is an increased volume of fluid surrounding the fetus (amniotic fluid). Polyhydramnios increases the risk of premature birth.  Beginning in infancy, affected individuals often fail to grow and gain weight at the expected rate (failure to thrive). They lose excess amounts of salt (sodium chloride) in their urine, which leads to dehydration, constipation, and increased urine production (polyuria). In addition, large amounts of calcium are lost through the urine (hypercalciuria), which can cause weakening of the bones (osteopenia). Some of the calcium is deposited in the kidneys as they are concentrating urine, leading to hardening of the kidney tissue (nephrocalcinosis). Bartter syndrome is also characterized by low levels of potassium in the blood (hypokalemia), which can result in muscle weakness, cramping, and fatigue. Rarely, affected children develop hearing loss caused by abnormalities in the inner ear (sensorineural deafness).  Two major forms of Bartter syndrome are distinguished by their age of onset and severity. One form begins before birth (antenatal) and is often life-threatening. The other form, often called the classical form, begins in early childhood and tends to be less severe. Once the genetic causes of Bartter syndrome were identified, researchers also split the disorder into different types based on the genes involved. Types I, II, and IV have the features of antenatal Bartter syndrome. Because type IV is also associated with hearing loss, it is sometimes called antenatal Bartter syndrome with sensorineural deafness. Type III usually has the features of classical Bartter syndrome.

Topic: Bartter syndrome
Question: What are the genetic changes related to Bartter syndrome ?
Answer: Bartter syndrome can be caused by mutations in at least five genes. Mutations in the SLC12A1 gene cause type I. Type II results from mutations in the KCNJ1 gene. Mutations in the CLCNKB gene are responsible for type III. Type IV can result from mutations in the BSND gene or from a combination of mutations in the CLCNKA and CLCNKB genes.  The genes associated with Bartter syndrome play important roles in normal kidney function. The proteins produced from these genes are involved in the kidneys' reabsorption of salt. Mutations in any of the five genes impair the kidneys' ability to reabsorb salt, leading to the loss of excess salt in the urine (salt wasting). Abnormalities of salt transport also affect the reabsorption of other charged atoms (ions), including potassium and calcium. The resulting imbalance of ions in the body leads to the major features of Bartter syndrome.  In some people with Bartter syndrome, the genetic cause of the disorder is unknown. Researchers are searching for additional genes that may be associated with this condition.

Topic: Alstrm syndrome
Question: What is (are) Alstrm syndrome ?
Answer: Alstrm syndrome is a rare condition that affects many body systems. Many of the signs and symptoms of this condition begin in infancy or early childhood, although some appear later in life.  Alstrm syndrome is characterized by a progressive loss of vision and hearing, a form of heart disease that enlarges and weakens the heart muscle (dilated cardiomyopathy), obesity, type 2 diabetes mellitus (the most common form of diabetes), and short stature. This disorder can also cause serious or life-threatening medical problems involving the liver, kidneys, bladder, and lungs. Some individuals with Alstrm syndrome have a skin condition called acanthosis nigricans, which causes the skin in body folds and creases to become thick, dark, and velvety. The signs and symptoms of Alstrm syndrome vary in severity, and not all affected individuals have all of the characteristic features of the disorder.

Topic: Alstrm syndrome
Question: What are the genetic changes related to Alstrm syndrome ?
Answer: Mutations in the ALMS1 gene cause Alstrm syndrome. The ALMS1 gene provides instructions for making a protein whose function is unknown. Mutations in this gene probably lead to the production of an abnormally short, nonfunctional version of the ALMS1 protein. This protein is normally present at low levels in most tissues, so a loss of the protein's normal function may help explain why the signs and symptoms of Alstrm syndrome affect many parts of the body.

Topic: purine nucleoside phosphorylase deficiency
Question: What is (are) purine nucleoside phosphorylase deficiency ?
Answer: Purine nucleoside phosphorylase deficiency is one of several disorders that damage the immune system and cause severe combined immunodeficiency (SCID). People with SCID lack virtually all immune protection from foreign invaders such as bacteria, viruses, and fungi. Affected individuals are prone to repeated and persistent infections that can be very serious or life-threatening. These infections are often caused by "opportunistic" organisms that ordinarily do not cause illness in people with a normal immune system. Infants with SCID typically grow much more slowly than healthy children and experience pneumonia, chronic diarrhea, and widespread skin rashes. Without successful treatment to restore immune function, children with SCID usually do not survive past early childhood.  About two-thirds of individuals with purine nucleoside phosphorylase deficiency have neurological problems, which may include developmental delay, intellectual disability, difficulties with balance and coordination (ataxia), and muscle stiffness (spasticity). People with purine nucleoside phosphorylase deficiency are also at increased risk of developing autoimmune disorders, which occur when the immune system malfunctions and attacks the body's tissues and organs.

Topic: purine nucleoside phosphorylase deficiency
Question: What are the genetic changes related to purine nucleoside phosphorylase deficiency ?
Answer: Purine nucleoside phosphorylase deficiency is caused by mutations in the PNP gene. The PNP gene provides instructions for making an enzyme called purine nucleoside phosphorylase. This enzyme is found throughout the body but is most active in specialized white blood cells called lymphocytes. These cells protect the body against potentially harmful invaders by making immune proteins called antibodies that tag foreign particles and germs for destruction or by directly attacking virus-infected cells. Lymphocytes are produced in specialized lymphoid tissues including the thymus and lymph nodes and then released into the blood. The thymus is a gland located behind the breastbone; lymph nodes are found throughout the body. Lymphocytes in the blood and in lymphoid tissues make up the immune system.  Purine nucleoside phosphorylase is known as a housekeeping enzyme because it clears away waste molecules that are generated when DNA is broken down. Mutations in the PNP gene reduce or eliminate the activity of purine nucleoside phosphorylase. The resulting excess of waste molecules and further reactions involving them lead to the buildup of a substance called deoxyguanosine triphosphate (dGTP) to levels that are toxic to lymphocytes. Immature lymphocytes in the thymus are particularly vulnerable to a toxic buildup of dGTP, which damages them and triggers their self-destruction (apoptosis). The number of lymphocytes in other lymphoid tissues is also greatly reduced, resulting in the immune deficiency characteristic of purine nucleoside phosphorylase deficiency.

Topic: hereditary cerebral amyloid angiopathy
Question: What is (are) hereditary cerebral amyloid angiopathy ?
Answer: Hereditary cerebral amyloid angiopathy is a condition that can cause a progressive loss of intellectual function (dementia), stroke, and other neurological problems starting in mid-adulthood. Due to neurological decline, this condition is typically fatal in one's sixties, although there is variation depending on the severity of the signs and symptoms. Most affected individuals die within a decade after signs and symptoms first appear, although some people with the disease have survived longer.  There are many different types of hereditary cerebral amyloid angiopathy. The different types are distinguished by their genetic cause and the signs and symptoms that occur. The various types of hereditary cerebral amyloid angiopathy are named after the regions where they were first diagnosed.  The Dutch type of hereditary cerebral amyloid angiopathy is the most common form. Stroke is frequently the first sign of the Dutch type and is fatal in about one third of people who have this condition. Survivors often develop dementia and have recurrent strokes. About half of individuals with the Dutch type who have one or more strokes will have recurrent seizures (epilepsy).  People with the Flemish and Italian types of hereditary cerebral amyloid angiopathy are prone to recurrent strokes and dementia. Individuals with the Piedmont type may have one or more strokes and typically experience impaired movements, numbness or tingling (paresthesias), confusion, or dementia.  The first sign of the Icelandic type of hereditary cerebral amyloid angiopathy is typically a stroke followed by dementia. Strokes associated with the Icelandic type usually occur earlier than the other types, with individuals typically experiencing their first stroke in their twenties or thirties.  Strokes are rare in people with the Arctic type of hereditary cerebral amyloid angiopathy, in which the first sign is usually memory loss that then progresses to severe dementia. Strokes are also uncommon in individuals with the Iowa type. This type is characterized by memory loss, problems with vocabulary and the production of speech, personality changes, and involuntary muscle twitches (myoclonus).  Two types of hereditary cerebral amyloid angiopathy, known as familial British dementia and familial Danish dementia, are characterized by dementia and movement problems. Strokes are uncommon in these types. People with the Danish type may also have clouding of the lens of the eyes (cataracts) or deafness.
