What is (are) carnitine-acylcarnitine translocase deficiency ?
Carnitine-acylcarnitine translocase (CACT) deficiency is a condition that prevents the body from using certain fats for energy, particularly during periods without food (fasting). Signs and symptoms of this disorder usually begin soon after birth and may include breathing problems, seizures, and an irregular heartbeat (arrhythmia). Affected individuals typically have low blood sugar (hypoglycemia) and a low level of ketones, which are produced during the breakdown of fats and used for energy. Together these signs are called hypoketotic hypoglycemia. People with CACT deficiency also usually have excess ammonia in the blood (hyperammonemia), an enlarged liver (hepatomegaly), and a weakened heart muscle (cardiomyopathy).  Many infants with CACT deficiency do not survive the newborn period. Some affected individuals have a less severe form of the condition and do not develop signs and symptoms until early childhood. These individuals are at risk for liver failure, nervous system damage, coma, and sudden death. + GHR + carnitine-acylcarnitine translocase deficiency

CACT deficiency is very rare; at least 30 cases have been reported. + GHR + carnitine-acylcarnitine translocase deficiency
What are the genetic changes related to carnitine-acylcarnitine translocase deficiency ?
Mutations in the SLC25A20 gene cause CACT deficiency. This gene provides instructions for making a protein called carnitine-acylcarnitine translocase (CACT). This protein is essential for fatty acid oxidation, a multistep process that breaks down (metabolizes) fats and converts them into energy. Fatty acid oxidation takes place within mitochondria, which are the energy-producing centers in cells. A group of fats called long-chain fatty acids must be attached to a substance known as carnitine to enter mitochondria. Once these fatty acids are joined with carnitine, the CACT protein transports them into mitochondria. Fatty acids are a major source of energy for the heart and muscles. During periods of fasting, fatty acids are also an important energy source for the liver and other tissues.  Although mutations in the SLC25A20 gene change the structure of the CACT protein in different ways, they all lead to a shortage (deficiency) of the transporter. Without enough functional CACT protein, long-chain fatty acids cannot be transported into mitochondria. As a result, these fatty acids are not converted to energy. Reduced energy production can lead to some of the features of CACT deficiency, such as hypoketotic hypoglycemia. Fatty acids and long-chain acylcarnitines (fatty acids still attached to carnitine) may also build up in cells and damage the liver, heart, and muscles. This abnormal buildup causes the other signs and symptoms of the disorder. + GHR + carnitine-acylcarnitine translocase deficiency
Is carnitine-acylcarnitine translocase deficiency inherited ?
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. + GHR + carnitine-acylcarnitine translocase deficiency

What is (are) adenosine monophosphate deaminase deficiency ?
Adenosine monophosphate (AMP) deaminase deficiency is a condition that can affect the muscles used for movement (skeletal muscles). People with this condition do not make enough of an enzyme called AMP deaminase. In most people, AMP deaminase deficiency does not cause any symptoms. People who do experience symptoms typically have muscle pain (myalgia) or weakness after exercise or prolonged physical activity. They often get tired more quickly and stay tired longer than would normally be expected. Some affected individuals have more severe symptoms, but it is unclear whether these symptoms are due solely to a lack of AMP deaminase or additional factors. Muscle weakness is typically apparent beginning in childhood or early adulthood.  Researchers have proposed three types of AMP deaminase deficiency, which are distinguished by their symptoms and genetic cause. + GHR + adenosine monophosphate deaminase deficiency
How many people are affected by adenosine monophosphate deaminase deficiency ?
AMP deaminase deficiency is one of the most common inherited muscle disorders in white populations, affecting 1 in 50 to 100 people. The prevalence is lower in African Americans, affecting an estimated 1 in 40,000 people, and the condition is even less common in the Japanese population. + GHR + adenosine monophosphate deaminase deficiency
What are the genetic changes related to adenosine monophosphate deaminase deficiency ?
Mutations in the AMPD1 gene cause AMP deaminase deficiency. The AMPD1 gene provides instructions for producing an enzyme called AMP deaminase. This enzyme is found in skeletal muscle, where it plays a role in producing energy within muscle cells. Mutations in the AMPD1 gene disrupt the function of AMP deaminase and impair the muscle cells' ability to produce energy. This lack of energy can lead to myalgia or other muscle problems associated with AMP deaminase deficiency.  The three types of AMP deaminase deficiency are known as the inherited type, acquired type, and coincidental inherited type.  Individuals with the inherited type have a mutation in both copies of the AMPD1 gene in each cell. Most people are asymptomatic, meaning they have no symptoms. Some people with AMP deaminase deficiency experience muscle weakness or pain following exercise.  The acquired type occurs in people who have decreased levels of AMP deaminase due to the presence of a muscle or joint condition.  People with the coincidental inherited type have a mutation in both copies of the AMPD1 gene. Additionally, they have a separate joint or muscle disorder. Some individuals experience more severe joint or muscle symptoms related to their disorder if they have AMP deaminase deficiency than do people without this enzyme deficiency. Most, however, do not have any symptoms associated with AMP deaminase deficiency.  It is not known why most people with this condition do not experience symptoms. Researchers speculate that additional mutations in other genes may be involved. + GHR + adenosine monophosphate deaminase deficiency

What is (are) vitiligo ?
Vitiligo is a condition that causes patchy loss of skin coloring (pigmentation). The average age of onset of vitiligo is in the mid-twenties, but it can appear at any age. It tends to progress over time, with larger areas of the skin losing pigment. Some people with vitiligo also have patches of pigment loss affecting the hair on their scalp or body.  Researchers have identified several forms of vitiligo. Generalized vitiligo (also called nonsegmental vitiligo), which is the most common form, involves loss of pigment (depigmentation) in patches of skin all over the body. Depigmentation typically occurs on the face, neck, and scalp, and around body openings such as the mouth and genitals. Sometimes pigment is lost in mucous membranes, such as the lips. Loss of pigmentation is also frequently seen in areas that tend to experience rubbing, impact, or other trauma, such as the hands, arms, and places where bones are close to the skin surface (bony prominences). Another form called segmental vitiligo is associated with smaller patches of depigmented skin that appear on one side of the body in a limited area; this occurs in about 10 percent of affected individuals.  Vitiligo is generally considered to be an autoimmune disorder. Autoimmune disorders occur when the immune system attacks the body's own tissues and organs. In people with vitiligo the immune system appears to attack the pigment cells (melanocytes) in the skin. About 15 to 25 percent of people with vitiligo are also affected by at least one other autoimmune disorder, particularly autoimmune thyroid disease, rheumatoid arthritis, type 1 diabetes, psoriasis, pernicious anemia, Addison disease, or systemic lupus erythematosus.  In the absence of other autoimmune conditions, vitiligo does not affect general health or physical functioning. However, concerns about appearance and ethnic identity are significant issues for many affected individuals. + GHR + vitiligo
How many people are affected by vitiligo ?
Vitiligo is a common disorder, affecting between 0.5 percent and 1 percent of the population worldwide. While the condition may be more noticeable in dark-skinned people, it occurs with similar frequency in all ethnic groups. + GHR + vitiligo
What are the genetic changes related to vitiligo ?
Variations in over 30 genes, occurring in different combinations, have been associated with an increased risk of developing vitiligo. Two of these genes are NLRP1 and PTPN22. The NLRP1 gene provides instructions for making a protein that is involved in the immune system, helping to regulate the process of inflammation. Inflammation occurs when the immune system sends signaling molecules and white blood cells to a site of injury or disease to fight microbial invaders and facilitate tissue repair. The body then stops (inhibits) the inflammatory response to prevent damage to its own cells and tissues.  The PTPN22 gene provides instructions for making a protein involved in signaling that helps control the activity of immune system cells called T cells. T cells identify foreign substances and defend the body against infection.  The variations in the NLRP1 and PTPN22 genes that are associated with an increased risk of developing vitiligo likely affect the activity of the NLRP1 and PTPN22 proteins, making it more difficult for the body to control inflammation and prevent the immune system from attacking its own tissues.  Studies indicate that variations in a number of other genes also affect the risk of vitiligo. Many of these genes are also involved in immune system function or melanocyte biology, and variations in each likely make only a small contribution to vitiligo risk. Some of the gene changes associated with an increased risk of vitiligo have also been associated with an increased risk of other autoimmune conditions.  It is unclear what specific circumstances trigger the immune system to attack melanocytes in the skin. Research suggests that the immune system of affected individuals may react abnormally to melanocytes that are stressed by factors such as chemicals or ultraviolet radiation. In addition, the melanocytes of people with vitiligo may be more susceptible to stress than those of the general population and therefore may be more likely to be attacked by the immune system. The condition probably results from a combination of genetic and environmental factors, most of which have not been identified. + GHR + vitiligo
Is vitiligo inherited ?
Vitiligo sometimes runs in families, but the inheritance pattern is complex since multiple causative factors are involved. About one-fifth of people with this condition have at least one close relative who is also affected. + GHR + vitiligo

What is (are) Rotor syndrome ?
Rotor syndrome is a relatively mild condition characterized by elevated levels of a substance called bilirubin in the blood (hyperbilirubinemia). Bilirubin is produced when red blood cells are broken down. It has an orange-yellow tint, and buildup of this substance can cause yellowing of the skin or whites of the eyes (jaundice). In people with Rotor syndrome, jaundice is usually evident shortly after birth or in childhood and may come and go; yellowing of the whites of the eyes (also called conjunctival icterus) is often the only symptom.  There are two forms of bilirubin in the body: a toxic form called unconjugated bilirubin and a nontoxic form called conjugated bilirubin. People with Rotor syndrome have a buildup of both unconjugated and conjugated bilirubin in their blood, but the majority is conjugated. + GHR + Rotor syndrome
How many people are affected by Rotor syndrome ?
Rotor syndrome is a rare condition, although its prevalence is unknown. + GHR + Rotor syndrome
What are the genetic changes related to Rotor syndrome ?
The SLCO1B1 and SLCO1B3 genes are involved in Rotor syndrome. Mutations in both genes are required for the condition to occur. The SLCO1B1 and SLCO1B3 genes provide instructions for making similar proteins, called organic anion transporting polypeptide 1B1 (OATP1B1) and organic anion transporting polypeptide 1B3 (OATP1B3), respectively. Both proteins are found in liver cells; they transport bilirubin and other compounds from the blood into the liver so that they can be cleared from the body. In the liver, bilirubin is dissolved in a digestive fluid called bile and then excreted from the body.  The SLCO1B1 and SLCO1B3 gene mutations that cause Rotor syndrome lead to abnormally short, nonfunctional OATP1B1 and OATP1B3 proteins or an absence of these proteins. Without the function of either transport protein, bilirubin is less efficiently taken up by the liver and removed from the body. The buildup of this substance leads to jaundice in people with Rotor syndrome. + GHR + Rotor syndrome
Is Rotor syndrome inherited ?
This condition is inherited in an autosomal recessive pattern. In autosomal recessive inheritance, both copies of a gene in each cell have mutations. In Rotor syndrome, an affected individual must have mutations in both the SLCO1B1 and the SLCO1B3 gene, so both copies of the two genes are altered. The parents of an individual with this condition each carry one altered copy of both genes, but they do not show signs and symptoms of the condition. + GHR + Rotor syndrome

What is (are) cyclic neutropenia ?
Cyclic neutropenia is a disorder that causes frequent infections and other health problems in affected individuals. People with this condition have recurrent episodes of neutropenia during which there is a shortage (deficiency) of neutrophils. Neutrophils are a type of white blood cell that plays a role in inflammation and in fighting infection. The episodes of neutropenia are apparent at birth or soon afterward. For most affected individuals, neutropenia recurs every 21 days and lasts about 3 to 5 days.  Neutropenia makes it more difficult for the body to fight off pathogens such as bacteria and viruses, so people with cyclic neutropenia typically develop recurrent infections of the sinuses, respiratory tract, and skin. Additionally, people with this condition often develop open sores (ulcers) in the mouth and colon, inflammation of the throat (pharyngitis) and gums (gingivitis), recurrent fever, or abdominal pain. People with cyclic neutropenia have these health problems only during episodes of neutropenia. At times when their neutrophil levels are normal, they are not at an increased risk of infection and inflammation. + GHR + cyclic neutropenia
How many people are affected by cyclic neutropenia ?
Cyclic neutropenia is a rare condition and is estimated to occur in 1 in 1 million individuals worldwide. + GHR + cyclic neutropenia
What are the genetic changes related to cyclic neutropenia ?
Mutations in the ELANE gene cause cyclic neutropenia. The ELANE gene provides instructions for making a protein called neutrophil elastase, which is found in neutrophils. When the body starts an immune response to fight an infection, neutrophils release neutrophil elastase. This protein then modifies the function of certain cells and proteins to help fight the infection.  ELANE gene mutations that cause cyclic neutropenia lead to an abnormal neutrophil elastase protein that seems to retain some of its function. However, neutrophils that produce abnormal neutrophil elastase protein appear to have a shorter lifespan than normal neutrophils. The shorter neutrophil lifespan is thought to be responsible for the cyclic nature of this condition. When the affected neutrophils die early, there is a period in which there is a shortage of neutrophils because it takes time for the body to replenish its supply. + GHR + cyclic neutropenia
Is cyclic neutropenia inherited ?
Cyclic neutropenia 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 most 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. + GHR + cyclic neutropenia

What is (are) adenylosuccinate lyase deficiency ?
Adenylosuccinate lyase deficiency is a neurological disorder that causes brain dysfunction (encephalopathy) leading to delayed development of mental and movement abilities (psychomotor delay), autistic behaviors that affect communication and social interaction, and seizures. A characteristic feature that can help with diagnosis of this condition is the presence of chemicals called succinylaminoimidazole carboxamide riboside (SAICAr) and succinyladenosine (S-Ado) in body fluids.  Adenylosuccinate lyase deficiency is classified into three forms based on the severity of the signs and symptoms. The most severe is the neonatal form. Signs and symptoms of this form can be detected at or before birth and can include impaired growth during fetal development and a small head size (microcephaly). Affected newborns have severe encephalopathy, which leads to a lack of movement, difficulty feeding, and life-threatening respiratory problems. Some affected babies develop seizures that do not improve with treatment. Because of the severity of the encephalopathy, infants with this form of the condition generally do not survive more than a few weeks after birth.  Adenylosuccinate lyase deficiency type I (also known as the severe form) is the most common. The signs and symptoms of this form begin in the first months of life. Affected babies have severe psychomotor delay, weak muscle tone (hypotonia), and microcephaly. Many affected infants develop recurrent seizures that are difficult to treat, and some exhibit autistic behaviors, such as repetitive behaviors and a lack of eye contact.  In individuals with adenylosuccinate lyase deficiency type II (also known as the moderate or mild form), development is typically normal for the first few years of life but then slows. Psychomotor delay is considered mild or moderate. Some children with this form of the condition develop seizures and autistic behaviors. + GHR + adenylosuccinate lyase deficiency
How many people are affected by adenylosuccinate lyase deficiency ?
Adenylosuccinate lyase deficiency is a rare disorder; fewer than 100 cases have been reported. The condition is most common in the Netherlands and Belgium, but it has been found worldwide. + GHR + adenylosuccinate lyase deficiency
What are the genetic changes related to adenylosuccinate lyase deficiency ?
All forms of adenylosuccinate lyase deficiency are caused by mutations in the ADSL gene. This gene provides instructions for making an enzyme called adenylosuccinate lyase, which performs two steps in the process that produces purine nucleotides. These nucleotides are building blocks of DNA, its chemical cousin RNA, and molecules such as ATP that serve as energy sources in the cell. Adenylosuccinate lyase converts a molecule called succinylaminoimidazole carboxamide ribotide (SAICAR) to aminoimidazole carboxamide ribotide (AICAR) and converts succinyladenosine monophosphate (SAMP) to adenosine monophosphate (AMP).  Most of the mutations involved in adenylosuccinate lyase deficiency change single protein building blocks (amino acids) in the adenylosuccinate lyase enzyme, which impairs its function. Reduced function of this enzyme leads to buildup of SAICAR and SAMP, which are converted through a different reaction to succinylaminoimidazole carboxamide riboside (SAICAr) and succinyladenosine (S-Ado). Researchers believe that SAICAr and S-Ado are toxic; damage to brain tissue caused by one or both of these substances likely underlies the neurological problems that occur in adenylosuccinate lyase deficiency.  Studies suggest that the amount of SAICAr relative to S-Ado reflects the severity of adenylosuccinate lyase deficiency. Individuals with more SAICAr than S-Ado have more severe encephalopathy and psychomotor delay. + GHR + adenylosuccinate lyase deficiency
