What is (are) hereditary pancreatitis ?
Hereditary pancreatitis is a genetic condition characterized by recurrent episodes of inflammation of the pancreas (pancreatitis). The pancreas produces enzymes that help digest food, and it also produces insulin, a hormone that controls blood sugar levels in the body. Episodes of pancreatitis can lead to permanent tissue damage and loss of pancreatic function.  Signs and symptoms of this condition usually begin in late childhood with an episode of acute pancreatitis. A sudden (acute) attack can cause abdominal pain, fever, nausea, or vomiting. An episode typically lasts from one to three days, although some people may experience severe episodes that last longer. Hereditary pancreatitis progresses to recurrent acute pancreatitis with multiple episodes of acute pancreatitis that recur over a period of at least a year; the number of episodes a person experiences varies. Recurrent acute pancreatitis leads to chronic pancreatitis, which occurs when the pancreas is persistently inflamed. Chronic pancreatitis usually develops by early adulthood in affected individuals. Signs and symptoms of chronic pancreatitis include occasional or frequent abdominal pain of varying severity, flatulence, and bloating. Many individuals with hereditary pancreatitis also develop abnormal calcium deposits in the pancreas (pancreatic calcifications) by early adulthood.  Years of inflammation damage the pancreas, causing the formation of scar tissue (fibrosis) in place of functioning pancreatic tissue. Pancreatic fibrosis leads to the loss of pancreatic function in many affected individuals. This loss of function can impair the production of digestive enzymes and disrupt normal digestion, leading to fatty stool (steatorrhea), weight loss, and protein and vitamin deficiencies. Because of a decrease in insulin production due to a loss of pancreatic function, about a quarter of individuals with hereditary pancreatitis will develop type 1 diabetes mellitus by mid-adulthood; the risk of developing diabetes increases with age.  Chronic pancreatic inflammation and damage to the pancreas increase the risk of developing pancreatic cancer. The risk is particularly high in people with hereditary pancreatitis who also smoke, use alcohol, have type 1 diabetes mellitus, or have a family history of cancer. In affected individuals who develop pancreatic cancer, it is typically diagnosed in mid-adulthood.  Complications from pancreatic cancer and type 1 diabetes mellitus are the most common causes of death in individuals with hereditary pancreatitis, although individuals with this condition are thought to have a normal life expectancy. + GHR + hereditary pancreatitis
How many people are affected by hereditary pancreatitis ?
Hereditary pancreatitis is thought to be a rare condition. In Europe, its prevalence is estimated to be 3 to 6 per million individuals. + GHR + hereditary pancreatitis
What are the genetic changes related to hereditary pancreatitis ?
Mutations in the PRSS1 gene cause most cases of hereditary pancreatitis. The PRSS1 gene provides instructions for making an enzyme called cationic trypsinogen. This enzyme is produced in the pancreas and helps with the digestion of food. When cationic trypsinogen is needed, it is released (secreted) from the pancreas and transported to the small intestine, where it is cut (cleaved) into its working or active form called trypsin. When digestion is complete and trypsin is no longer needed, the enzyme is broken down.  Some PRSS1 gene mutations that cause hereditary pancreatitis result in the production of a cationic trypsinogen enzyme that is prematurely converted to trypsin while it is still in the pancreas. Other mutations prevent trypsin from being broken down. These changes result in elevated levels of trypsin in the pancreas. Trypsin activity in the pancreas can damage pancreatic tissue and can also trigger an immune response, causing inflammation in the pancreas.  It is estimated that 65 to 80 percent of people with hereditary pancreatitis have mutations in the PRSS1 gene. The remaining cases are caused by mutations in other genes, some of which have not been identified. + GHR + hereditary pancreatitis
Is hereditary pancreatitis inherited ?
When hereditary pancreatitis is caused by mutations in the PRSS1 gene, 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. In some cases, an affected person inherits the PRSS1 gene 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.  It is estimated that 20 percent of people who have the altered PRSS1 gene never have an episode of pancreatitis. (This situation is known as reduced penetrance.) It is unclear why some people with a mutated gene never develop signs and symptoms of the disease. + GHR + hereditary pancreatitis

What is (are) alternating hemiplegia of childhood ?
Alternating hemiplegia of childhood is a neurological condition characterized by recurrent episodes of temporary paralysis, often affecting one side of the body (hemiplegia). During some episodes, the paralysis alternates from one side of the body to the other or affects both sides at the same time. These episodes begin in infancy or early childhood, usually before 18 months of age, and the paralysis lasts from minutes to days.  In addition to paralysis, affected individuals can have sudden attacks of uncontrollable muscle activity; these can cause involuntary limb movements (choreoathetosis), muscle tensing (dystonia), movement of the eyes (nystagmus), or shortness of breath (dyspnea). People with alternating hemiplegia of childhood may also experience sudden redness and warmth (flushing) or unusual paleness (pallor) of the skin. These attacks can occur during or separately from episodes of hemiplegia.  The episodes of hemiplegia or uncontrolled movements can be triggered by certain factors, such as stress, extreme tiredness, cold temperatures, or bathing, although the trigger is not always known. A characteristic feature of alternating hemiplegia of childhood is that all symptoms disappear while the affected person is sleeping but can reappear shortly after awakening. The number and length of the episodes initially worsen throughout childhood but then begin to decrease over time. The uncontrollable muscle movements may disappear entirely, but the episodes of hemiplegia occur throughout life.  Alternating hemiplegia of childhood also causes mild to severe cognitive problems. Almost all affected individuals have some level of developmental delay and intellectual disability. Their cognitive functioning typically declines over time. + GHR + alternating hemiplegia of childhood
How many people are affected by alternating hemiplegia of childhood ?
Alternating hemiplegia of childhood is a rare condition that affects approximately 1 in 1 million people. + GHR + alternating hemiplegia of childhood
What are the genetic changes related to alternating hemiplegia of childhood ?
Alternating hemiplegia of childhood is primarily caused by mutations in the ATP1A3 gene. Very rarely, a mutation in the ATP1A2 gene is involved in the condition. These genes provide instructions for making very similar proteins. They function as different forms of one piece, the alpha subunit, of a larger protein complex called Na+/K+ ATPase; the two versions of the complex are found in different parts of the brain. Both versions play a critical role in the normal function of nerve cells (neurons). Na+/K+ ATPase transports charged atoms (ions) into and out of neurons, which is an essential part of the signaling process that controls muscle movement.  Mutations in the ATP1A3 or ATP1A2 gene reduce the activity of the Na+/K+ ATPase, impairing its ability to transport ions normally. It is unclear how a malfunctioning Na+/K+ ATPase causes the episodes of paralysis or uncontrollable movements characteristic of alternating hemiplegia of childhood. + GHR + alternating hemiplegia of childhood
Is alternating hemiplegia of childhood inherited ?
Alternating hemiplegia of childhood is considered an autosomal dominant condition, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases of alternating hemiplegia of childhood result from new mutations in the gene and occur in people with no history of the disorder in their family. However, the condition can also run in families. For unknown reasons, the signs and symptoms are typically milder when the condition is found in multiple family members than when a single individual is affected. + GHR + alternating hemiplegia of childhood

What is (are) Partington syndrome ?
Partington syndrome is a neurological disorder that causes intellectual disability along with a condition called focal dystonia that particularly affects movement of the hands. Partington syndrome usually occurs in males; when it occurs in females, the signs and symptoms are often less severe.  The intellectual disability associated with Partington syndrome usually ranges from mild to moderate. Some affected individuals have characteristics of autism spectrum disorders that affect communication and social interaction. Recurrent seizures (epilepsy) may also occur in Partington syndrome.  Focal dystonia of the hands is a feature that distinguishes Partington syndrome from other intellectual disability syndromes. Dystonias are a group of movement problems characterized by involuntary, sustained muscle contractions; tremors; and other uncontrolled movements. The term "focal" refers to a type of dystonia that affects a single part of the body, in this case the hands. In Partington syndrome, focal dystonia of the hands, which is called the Partington sign, begins in early childhood and gradually gets worse. This condition typically causes difficulty with grasping movements or using a pen or pencil.  People with Partington syndrome may also have dystonia affecting other parts of the body; dystonia affecting the muscles in the face and those involved in speech may cause impaired speech (dysarthria). People with this disorder may also have an awkward way of walking (gait). Signs and symptoms can vary widely, even within the same family. + GHR + Partington syndrome
How many people are affected by Partington syndrome ?
The prevalence of Partington syndrome is unknown. About 20 cases have been described in the medical literature. + GHR + Partington syndrome
What are the genetic changes related to Partington syndrome ?
Partington syndrome is caused by mutations in the ARX gene. This gene provides instructions for producing a protein that regulates the activity of other genes. Within the developing brain, the ARX protein is involved with movement (migration) and communication of nerve cells (neurons). In particular, this protein regulates genes that play a role in the migration of specialized neurons (interneurons) to their proper location. Interneurons relay signals between other neurons.  The normal ARX protein contains four regions where a protein building block (amino acid) called alanine is repeated multiple times. These stretches of alanines are known as polyalanine tracts. The most common mutation that causes Partington syndrome, a duplication of genetic material written as c.428_451dup, adds extra alanines to the second polyalanine tract in the ARX protein. This type of mutation is called a polyalanine repeat expansion. The expansion likely impairs ARX protein function and may disrupt normal interneuron migration in the developing brain, leading to the intellectual disability and dystonia characteristic of Partington syndrome. + GHR + Partington syndrome
Is Partington syndrome inherited ?
This condition is inherited in an X-linked recessive pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. Females with one altered copy of the gene may have some signs and symptoms related to the condition. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. + GHR + Partington syndrome

What is (are) Ewing sarcoma ?
Ewing sarcoma is a cancerous tumor that occurs in bones or soft tissues, such as cartilage or nerves. There are several types of Ewing sarcoma, including Ewing sarcoma of bone, extraosseous Ewing sarcoma, peripheral primitive neuroectodermal tumor (pPNET), and Askin tumor. These tumors are considered to be related because they have similar genetic causes. These types of Ewing sarcoma can be distinguished from one another by the tissue in which the tumor develops. Approximately 87 percent of Ewing sarcomas are Ewing sarcoma of bone, which is a bone tumor that usually occurs in the thigh bones (femurs), pelvis, ribs, or shoulder blades. Extraosseous (or extraskeletal) Ewing sarcoma describes tumors in the soft tissues around bones, such as cartilage. pPNETs occur in nerve tissue and can be found in many parts of the body. A type of pPNET found in the chest is called Askin tumor.  Ewing sarcomas most often occur in children and young adults. Affected individuals usually feel stiffness, pain, swelling, or tenderness of the bone or surrounding tissue. Sometimes, there is a lump near the surface of the skin that feels warm and soft to the touch. Often, children have a fever that does not go away. Ewing sarcoma of bone can cause weakening of the involved bone, and affected individuals may have a broken bone with no obvious cause.  It is common for Ewing sarcoma to spread to other parts of the body (metastasize), usually to the lungs, to other bones, or to the bone marrow. + GHR + Ewing sarcoma
How many people are affected by Ewing sarcoma ?
Approximately 3 per 1 million children each year are diagnosed with a Ewing sarcoma. It is estimated that, in the United States, 250 children are diagnosed with one of these types of tumor each year. Ewing sarcoma accounts for about 1.5 percent of all childhood cancers, and it is the second most common type of bone tumor in children (the most common type of bone cancer is called osteosarcoma). + GHR + Ewing sarcoma
What are the genetic changes related to Ewing sarcoma ?
The most common mutation that causes Ewing sarcoma involves two genes, the EWSR1 gene on chromosome 22 and the FLI1 gene on chromosome 11. A rearrangement (translocation) of genetic material between chromosomes 22 and 11, written as t(11;22), fuses part of the EWSR1 gene with part of the FLI1 gene, creating the EWSR1/FLI1 fusion gene. This mutation is acquired during a person's lifetime and is present only in tumor cells. This type of genetic change, called a somatic mutation, is not inherited.  The protein produced from the EWSR1/FLI1 fusion gene, called EWS/FLI, has functions of the protein products of both genes. The FLI protein, produced from the FLI1 gene, attaches (binds) to DNA and regulates an activity called transcription, which is the first step in the production of proteins from genes. The FLI protein controls the growth and development of some cell types by regulating the transcription of certain genes. The EWS protein, produced from the EWSR1 gene, also regulates transcription. The EWS/FLI protein has the DNA-binding function of the FLI protein as well as the transcription regulation function of the EWS protein. It is thought that the EWS/FLI protein turns the transcription of a variety of genes on and off abnormally. This dysregulation of transcription leads to uncontrolled growth and division (proliferation) and abnormal maturation and survival of cells, causing tumor development.  The EWSR1/FLI1 fusion gene occurs in approximately 85 percent of Ewing sarcomas. Translocations that fuse the EWSR1 gene with other genes that are related to the FLI1 gene can also cause these types of tumors, although these alternative translocations are relatively uncommon. The fusion proteins produced from the less common gene translocations have the same function as the EWS/FLI protein. + GHR + Ewing sarcoma

What is (are) Tay-Sachs disease ?
Tay-Sachs disease is a rare inherited disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord.  The most common form of Tay-Sachs disease becomes apparent in infancy. Infants with this disorder typically appear normal until the age of 3 to 6 months, when their development slows and muscles used for movement weaken. Affected infants lose motor skills such as turning over, sitting, and crawling. They also develop an exaggerated startle reaction to loud noises. As the disease progresses, children with Tay-Sachs disease experience seizures, vision and hearing loss, intellectual disability, and paralysis. An eye abnormality called a cherry-red spot, which can be identified with an eye examination, is characteristic of this disorder. Children with this severe infantile form of Tay-Sachs disease usually live only into early childhood.  Other forms of Tay-Sachs disease are very rare. Signs and symptoms can appear in childhood, adolescence, or adulthood and are usually milder than those seen with the infantile form. Characteristic features include muscle weakness, loss of muscle coordination (ataxia) and other problems with movement, speech problems, and mental illness. These signs and symptoms vary widely among people with late-onset forms of Tay-Sachs disease. + GHR + Tay-Sachs disease
How many people are affected by Tay-Sachs disease ?
Tay-Sachs disease is very rare in the general population. The genetic mutations that cause this disease are more common in people of Ashkenazi (eastern and central European) Jewish heritage than in those with other backgrounds. The mutations responsible for this disease are also more common in certain French-Canadian communities of Quebec, the Old Order Amish community in Pennsylvania, and the Cajun population of Louisiana. + GHR + Tay-Sachs disease
What are the genetic changes related to Tay-Sachs disease ?
Mutations in the HEXA gene cause Tay-Sachs disease. The HEXA gene provides instructions for making part of an enzyme called beta-hexosaminidase A, which plays a critical role in the brain and spinal cord. This enzyme is located in lysosomes, which are structures in cells that break down toxic substances and act as recycling centers. Within lysosomes, beta-hexosaminidase A helps break down a fatty substance called GM2 ganglioside.  Mutations in the HEXA gene disrupt the activity of beta-hexosaminidase A, which prevents the enzyme from breaking down GM2 ganglioside. As a result, this substance accumulates to toxic levels, particularly in neurons in the brain and spinal cord. Progressive damage caused by the buildup of GM2 ganglioside leads to the destruction of these neurons, which causes the signs and symptoms of Tay-Sachs disease.  Because Tay-Sachs disease impairs the function of a lysosomal enzyme and involves the buildup of GM2 ganglioside, this condition is sometimes referred to as a lysosomal storage disorder or a GM2-gangliosidosis. + GHR + Tay-Sachs disease
Is Tay-Sachs disease 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 + Tay-Sachs disease
