Topic: congenital afibrinogenemia
Question: Is congenital afibrinogenemia inherited ?
Answer: Congenital afibrinogenemia 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. The parents have about half the normal level of fibrinogen in their blood but typically do not show signs and symptoms of the condition.

Topic: epidermolysis bullosa with pyloric atresia
Question: What is (are) epidermolysis bullosa with pyloric atresia ?
Answer: Epidermolysis bullosa with pyloric atresia (EB-PA) is a condition that affects the skin and digestive tract. This condition is one of several forms of epidermolysis bullosa, a group of genetic conditions that cause the skin to be fragile and to blister easily. Affected infants are often born with widespread blistering and areas of missing skin. Blisters continue to appear in response to minor injury or friction, such as rubbing or scratching. Most often, blisters occur over the whole body and affect mucous membranes such as the moist lining of the mouth and digestive tract.  People with EB-PA are also born with pyloric atresia, which is an obstruction of the lower part of the stomach (the pylorus). This obstruction prevents food from emptying out of the stomach into the intestine. Signs of pyloric atresia include vomiting, a swollen (distended) abdomen, and an absence of stool. Pyloric atresia is life-threatening and must be repaired with surgery soon after birth.  Other complications of EB-PA can include fusion of the skin between the fingers and toes, abnormalities of the fingernails and toenails, joint deformities (contractures) that restrict movement, and hair loss (alopecia). Some affected individuals are also born with malformations of the urinary tract, including the kidneys and bladder.  Because the signs and symptoms of EB-PA are so severe, many infants with this condition do not survive beyond the first year of life. In those who survive, the condition may improve with time; some affected individuals have little or no blistering later in life. However, many affected individuals who live past infancy experience severe medical problems, including blistering and the formation of red, bumpy patches called granulation tissue. Granulation tissue most often forms on the skin around the mouth, nose, fingers, and toes. It can also build up in the airway, leading to difficulty breathing.

Topic: epidermolysis bullosa with pyloric atresia
Question: What are the genetic changes related to epidermolysis bullosa with pyloric atresia ?
Answer: EB-PA can be caused by mutations in the ITGA6, ITGB4, and PLEC genes. These genes provide instructions for making proteins with critical roles in the skin and digestive tract.  ITGB4 gene mutations are the most common cause of EB-PA; these mutations are responsible for about 80 percent of all cases. ITGA6 gene mutations cause about 5 percent of cases. The proteins produced from the ITGA6 and ITGB4 genes join to form a protein known as 64 integrin. This protein plays an important role in strengthening and stabilizing the skin by helping to attach the top layer of skin (the epidermis) to underlying layers. Mutations in either the ITGA6 gene or the ITGB4 gene lead to the production of a defective or nonfunctional version of 64 integrin, or prevent cells from making any of this protein. A shortage of functional 64 integrin causes cells in the epidermis to be fragile and easily damaged. Friction or other minor trauma can cause the skin layers to separate, leading to the formation of blisters.  About 15 percent of all cases of EB-PA result from mutations in the PLEC gene. This gene provides instructions for making a protein called plectin. Like 64 integrin, plectin helps attach the epidermis to underlying layers of skin. Some PLEC gene mutations prevent the cell from making any functional plectin, while other mutations result in an abnormal form of the protein. When plectin is altered or missing, the skin is less resistant to friction and minor trauma and blisters easily.  Researchers are working to determine how mutations in the ITGA6, ITGB4, and PLEC genes lead to pyloric atresia in people with EB-PA. Studies suggest that these genes are important for the normal development of the digestive tract.

Topic: fucosidosis
Question: What is (are) fucosidosis ?
Answer: Fucosidosis is a condition that affects many areas of the body, especially the brain. Affected individuals have intellectual disability that worsens with age, and many develop dementia later in life. People with this condition often have delayed development of motor skills such as walking; the skills they do acquire deteriorate over time. Additional signs and symptoms of fucosidosis include impaired growth; abnormal bone development (dysostosis multiplex); seizures; abnormal muscle stiffness (spasticity); clusters of enlarged blood vessels forming small, dark red spots on the skin (angiokeratomas); distinctive facial features that are often described as "coarse"; recurrent respiratory infections; and abnormally large abdominal organs (visceromegaly).  In severe cases, symptoms typically appear in infancy, and affected individuals usually live into late childhood. In milder cases, symptoms begin at age 1 or 2, and affected individuals tend to survive into mid-adulthood.  In the past, researchers described two types of this condition based on symptoms and age of onset, but current opinion is that the two types are actually a single disorder with signs and symptoms that range in severity.

Topic: fucosidosis
Question: What are the genetic changes related to fucosidosis ?
Answer: Mutations in the FUCA1 gene cause fucosidosis. The FUCA1 gene provides instructions for making an enzyme called alpha-L-fucosidase. This enzyme plays a role in the breakdown of complexes of sugar molecules (oligosaccharides) attached to certain proteins (glycoproteins) and fats (glycolipids). Alpha-L-fucosidase is responsible for cutting (cleaving) off a sugar molecule called fucose toward the end of the breakdown process.  FUCA1 gene mutations severely reduce or eliminate the activity of the alpha-L-fucosidase enzyme. A lack of enzyme activity results in an incomplete breakdown of glycolipids and glycoproteins. These partially broken down compounds gradually accumulate within various cells and tissues throughout the body and cause cells to malfunction. Brain cells are particularly sensitive to the buildup of glycolipids and glycoproteins, which can result in cell death. Loss of brain cells is thought to cause the neurological symptoms of fucosidosis. Accumulation of glycolipids and glycoproteins also occurs in other organs such as the liver, spleen, skin, heart, pancreas, and kidneys, contributing to the additional symptoms of fucosidosis.

Topic: L1 syndrome
Question: What is (are) L1 syndrome ?
Answer: L1 syndrome is an inherited disorder that primarily affects the nervous system. L1 syndrome involves a variety of features that were once thought to be distinct disorders, but are now considered to be part of the same syndrome. The most common characteristics of L1 syndrome are muscle stiffness (spasticity) of the lower limbs, intellectual disability, increased fluid in the center of the brain (hydrocephalus), and thumbs bent toward the palm (adducted thumbs). People with L1 syndrome can also have difficulty speaking (aphasia), seizures, and underdeveloped or absent tissue connecting the left and right halves of the brain (agenesis of the corpus callosum). The symptoms of L1 syndrome vary widely among affected individuals, even among members of the same family. Because this disorder involves spasticity of the lower limbs, L1 syndrome is sometimes referred to as spastic paraplegia type 1 (SPG1).

Topic: L1 syndrome
Question: What are the genetic changes related to L1 syndrome ?
Answer: L1 syndrome is caused by mutations in the L1CAM gene. The L1CAM gene provides instructions for producing the L1 protein, which is found throughout the nervous system on the surface of nerve cells (neurons). The L1 protein plays a role in the development and organization of neurons, the formation of the protective sheath (myelin) that surrounds certain neurons, and the formation of junctions between nerve cells (synapses), where cell-to-cell communication occurs. Mutations in the L1 protein can interfere with these developmental processes. Research suggests that a disruption in the development and function of neurons causes the signs and symptoms of L1 syndrome.

Topic: L1 syndrome
Question: Is L1 syndrome inherited ?
Answer: 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. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

Topic: acute promyelocytic leukemia
Question: What is (are) acute promyelocytic leukemia ?
Answer: Acute promyelocytic leukemia is a form of acute myeloid leukemia, a cancer of the blood-forming tissue (bone marrow). In normal bone marrow, hematopoietic stem cells produce red blood cells (erythrocytes) that carry oxygen, white blood cells (leukocytes) that protect the body from infection, and platelets (thrombocytes) that are involved in blood clotting. In acute promyelocytic leukemia, immature white blood cells called promyelocytes accumulate in the bone marrow. The overgrowth of promyelocytes leads to a shortage of normal white and red blood cells and platelets in the body, which causes many of the signs and symptoms of the condition.  People with acute promyelocytic leukemia are especially susceptible to developing bruises, small red dots under the skin (petechiae), nosebleeds, bleeding from the gums, blood in the urine (hematuria), or excessive menstrual bleeding. The abnormal bleeding and bruising occur in part because of the low number of platelets in the blood (thrombocytopenia) and also because the cancerous cells release substances that cause excessive bleeding.  The low number of red blood cells (anemia) can cause people with acute promyelocytic leukemia to have pale skin (pallor) or excessive tiredness (fatigue). In addition, affected individuals may heal slowly from injuries or have frequent infections due to the loss of normal white blood cells that fight infection. Furthermore, the leukemic cells can spread to the bones and joints, which may cause pain in those areas. Other general signs and symptoms may occur as well, such as fever, loss of appetite, and weight loss.  Acute promyelocytic leukemia is most often diagnosed around age 40, although it can be diagnosed at any age.

Topic: acute promyelocytic leukemia
Question: What are the genetic changes related to acute promyelocytic leukemia ?
Answer: The mutation that causes acute promyelocytic leukemia involves two genes, the PML gene on chromosome 15 and the RARA gene on chromosome 17. A rearrangement of genetic material (translocation) between chromosomes 15 and 17, written as t(15;17), fuses part of the PML gene with part of the RARA gene. The protein produced from this fused gene is known as PML-RAR. This mutation is acquired during a person's lifetime and is present only in certain cells. This type of genetic change, called a somatic mutation, is not inherited.  The PML-RAR protein functions differently than the protein products of the normal PML and RARA genes. The protein produced from the RARA gene, RAR, is involved in the regulation of gene transcription, which is the first step in protein production. Specifically, this protein helps control the transcription of certain genes important in the maturation (differentiation) of white blood cells beyond the promyelocyte stage. The protein produced from the PML gene acts as a tumor suppressor, which means it prevents cells from growing and dividing too rapidly or in an uncontrolled way. The PML-RAR protein interferes with the normal function of both the PML and the RAR proteins. As a result, blood cells are stuck at the promyelocyte stage, and they proliferate abnormally. Excess promyelocytes accumulate in the bone marrow and normal white blood cells cannot form, leading to acute promyelocytic leukemia.  The PML-RARA gene fusion accounts for up to 98 percent of cases of acute promyelocytic leukemia. Translocations involving the RARA gene and other genes have been identified in a few cases of acute promyelocytic leukemia.

Topic: renal hypouricemia
Question: What is (are) renal hypouricemia ?
Answer: Renal hypouricemia is a kidney (renal) disorder that results in a reduced amount of uric acid in the blood. Uric acid is a byproduct of certain normal chemical reactions in the body. In the bloodstream it acts as an antioxidant, protecting cells from the damaging effects of unstable molecules called free radicals. However, having too much uric acid in the body is toxic, so excess uric acid is removed from the body in urine.  People with renal hypouricemia have little to no uric acid in their blood; they release an excessive amount of it in the urine. In many affected individuals, renal hypouricemia causes no signs or symptoms. However, some people with this condition develop kidney problems. After strenuous exercise, they can develop exercise-induced acute kidney injury, which causes pain in their sides and lower back as well as nausea and vomiting that can last several hours.  Because an excessive amount of uric acid passes through the kidneys to be excreted in urine in people with renal hypouricemia, they have an increased risk of developing kidney stones (nephrolithiasis) formed from uric acid crystals. These uric acid stones can damage the kidneys and lead to episodes of blood in the urine (hematuria). Rarely, people with renal hypouricemia develop life-threatening kidney failure.

Topic: renal hypouricemia
Question: What are the genetic changes related to renal hypouricemia ?
Answer: Mutations in the SLC22A12 or SLC2A9 gene cause renal hypouricemia. These genes provide instructions for making proteins called urate transporter 1 (URAT1) and glucose transporter 9 (GLUT9), respectively. These proteins are found in the kidneys, specifically in structures called proximal tubules. These structures help to reabsorb needed nutrients, water, and other materials into the blood and excrete unneeded substances into the urine. Within the proximal tubules, both the URAT1 and GLUT9 proteins reabsorb uric acid into the bloodstream or release it into the urine, depending on the body's needs. Most uric acid that is filtered through the kidneys is reabsorbed into the bloodstream; about 10 percent is released into urine.  Mutations that cause renal hypouricemia lead to the production of URAT1 or GLUT9 protein with a reduced ability to reabsorb uric acid into the bloodstream. Instead, large amounts of uric acid are released in the urine. The specific cause of the signs and symptoms of renal hypouricemia is unclear. Researchers suspect that when additional uric acid is produced during exercise and passed through the kidneys, it could lead to tissue damage. Alternatively, without the antioxidant properties of uric acid, free radicals could cause tissue damage in the kidneys. Another possibility is that other substances are prevented from being reabsorbed along with uric acid; accumulation of these substances in the kidneys could cause tissue damage. It is likely that individuals with renal hypouricemia who have mild or no symptoms have enough protein function to reabsorb a sufficient amount of uric acid into the bloodstream to prevent severe kidney problems.

Question: Is renal hypouricemia inherited ?
Answer: This condition is typically inherited in an autosomal recessive pattern, which means both copies of the SLC22A12 or SLC2A9 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 usually do not show signs and symptoms of the condition.  Sometimes, individuals with one SLC2A9 gene mutation in each cell have reduced levels of uric acid. The levels usually are not as low as they are in people who have mutations in both copies of the gene, and they often do not cause any signs or symptoms. Rarely, people who carry one copy of the mutated gene will develop uric acid kidney stones.
