Question: What are the genetic changes related to chronic granulomatous disease ?
Answer: Mutations in the CYBA, CYBB, NCF1, NCF2, or NCF4 gene can cause chronic granulomatous disease. There are five types of this condition that are distinguished by the gene that is involved. The proteins produced from the affected genes are parts (subunits) of an enzyme complex called NADPH oxidase, which plays an essential role in the immune system. Specifically, NADPH oxidase is primarily active in immune system cells called phagocytes. These cells catch and destroy foreign invaders such as bacteria and fungi. Within phagocytes, NADPH oxidase is involved in the production of a toxic molecule called superoxide. Superoxide is used to generate other toxic substances, which play a role in killing foreign invaders and preventing them from reproducing in the body and causing illness. NADPH oxidase is also thought to regulate the activity of immune cells called neutrophils. These cells play a role in adjusting the inflammatory response to optimize healing and reduce injury to the body.  Mutations in the CYBA, CYBB, NCF1, NCF2, and NCF4 genes result in the production of proteins with little or no function or the production of no protein at all. Mutations in the genes that cause chronic granulomatous disease that prevent the production of any functional protein are designated "0". For example, mutations in the CYBB gene that lead to no functional beta chain are designated CYBB0. Mutations that lead to a reduction of the amount of protein produced are designated "-", for example, CYBB-.  Without any one of its subunit proteins, NADPH oxidase cannot assemble or function properly. As a result, phagocytes are unable to kill foreign invaders and neutrophil activity is not regulated. A lack of NADPH oxidase leaves affected individuals vulnerable to many types of infection and excessive inflammation.  Some people with chronic granulomatous disease do not have an identified mutation in any of these genes. The cause of the condition in these individuals is unknown.

Question: Is chronic granulomatous disease inherited ?
Answer: When chronic granulomatous disease is caused by mutations in the CYBB gene, the condition is inherited in an X-linked recessive pattern. The CYBB gene 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. Rarely, females with one altered copy of the CYBB gene have mild symptoms of chronic granulomatous disease, such as an increased frequency of bacterial or fungal infections.  When chronic granulomatous disease is caused by CYBA, NCF1, NCF2, or NCF4 gene mutations, the 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. Men and women are affected by autosomal recessive conditions equally.

Topic: factor X deficiency
Question: What is (are) factor X deficiency ?
Answer: Factor X deficiency is a rare bleeding disorder that varies in severity among affected individuals. The signs and symptoms of this condition can begin at any age, although the most severe cases are apparent in childhood. Factor X deficiency commonly causes nosebleeds, easy bruising, bleeding under the skin, bleeding of the gums, blood in the urine (hematuria), and prolonged or excessive bleeding following surgery or trauma. Women with factor X deficiency can have heavy or prolonged menstrual bleeding (menorrhagia) or excessive bleeding in childbirth, and may be at increased risk of pregnancy loss (miscarriage). Bleeding into joint spaces (hemarthrosis) occasionally occurs. Severely affected individuals have an increased risk of bleeding inside the skull (intracranial hemorrhage), in the lungs (pulmonary hemorrhage), or in the gastrointestinal tract, which can be life-threatening.

Topic: factor X deficiency
Question: What are the genetic changes related to factor X deficiency ?
Answer: The inherited form of factor X deficiency, known as congenital factor X deficiency, is caused by mutations in the F10 gene, which provides instructions for making a protein called coagulation factor X. This protein plays a critical role in the coagulation system, which is a series of chemical reactions that forms blood clots in response to injury. Some F10 gene mutations that cause factor X deficiency reduce the amount of coagulation factor X in the bloodstream, resulting in a form of the disorder called type I. Other F10 gene mutations result in the production of a coagulation factor X protein with impaired function, leading to type II factor X deficiency. Reduced quantity or function of coagulation factor X prevents blood from clotting normally, causing episodes of abnormal bleeding that can be severe.  A non-inherited form of the disorder, called acquired factor X deficiency, is more common than the congenital form. Acquired factor X deficiency can be caused by other disorders such as severe liver disease or systemic amyloidosis, a condition involving the accumulation of abnormal proteins called amyloids. Acquired factor X deficiency can also be caused by certain drugs such as medicines that prevent clotting, or by a deficiency of vitamin K.

Topic: factor X deficiency
Question: Is factor X deficiency inherited ?
Answer: When this condition is caused by mutations in the F10 gene, it 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.  Acquired factor X deficiency is not inherited, and generally occurs in individuals with no history of the disorder in their family.

Topic: osteopetrosis
Question: How many people are affected by osteopetrosis ?
Answer: Autosomal dominant osteopetrosis is the most common form of the disorder, affecting about 1 in 20,000 people. Autosomal recessive osteopetrosis is rarer, occurring in an estimated 1 in 250,000 people.  Other forms of osteopetrosis are very rare. Only a few cases of intermediate autosomal osteopetrosis and OL-EDA-ID have been reported in the medical literature.

Topic: osteopetrosis
Question: What are the genetic changes related to osteopetrosis ?
Answer: Mutations in at least nine genes cause the various types of osteopetrosis. Mutations in the CLCN7 gene are responsible for about 75 percent of cases of autosomal dominant osteopetrosis, 10 to 15 percent of cases of autosomal recessive osteopetrosis, and all known cases of intermediate autosomal osteopetrosis. TCIRG1 gene mutations cause about 50 percent of cases of autosomal recessive osteopetrosis. Mutations in other genes are less common causes of autosomal dominant and autosomal recessive forms of the disorder. The X-linked type of osteopetrosis, OL-EDA-ID, results from mutations in the IKBKG gene. In about 30 percent of all cases of osteopetrosis, the cause of the condition is unknown.  The genes associated with osteopetrosis are involved in the formation, development, and function of specialized cells called osteoclasts. These cells break down bone tissue during bone remodeling, a normal process in which old bone is removed and new bone is created to replace it. Bones are constantly being remodeled, and the process is carefully controlled to ensure that bones stay strong and healthy.  Mutations in any of the genes associated with osteopetrosis lead to abnormal or missing osteoclasts. Without functional osteoclasts, old bone is not broken down as new bone is formed. As a result, bones throughout the skeleton become unusually dense. The bones are also structurally abnormal, making them prone to fracture. These problems with bone remodeling underlie all of the major features of osteopetrosis.

Topic: osteopetrosis
Question: Is osteopetrosis inherited ?
Answer: Osteopetrosis can have several different patterns of inheritance. Most commonly, the disorder has an autosomal dominant inheritance pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. Most people with autosomal dominant osteopetrosis inherit the condition from an affected parent.  Osteopetrosis can also be inherited in an autosomal recessive pattern, which means both copies of a 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.  OL-EDA-ID is inherited in an X-linked recessive pattern. The IKBKG gene 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: leukocyte adhesion deficiency type 1
Question: What is (are) leukocyte adhesion deficiency type 1 ?
Answer: Leukocyte adhesion deficiency type 1 is a disorder that causes the immune system to malfunction, resulting in a form of immunodeficiency. Immunodeficiencies are conditions in which the immune system is not able to protect the body effectively from foreign invaders such as viruses, bacteria, and fungi. Starting from birth, people with leukocyte adhesion deficiency type 1 develop serious bacterial and fungal infections.  One of the first signs of leukocyte adhesion deficiency type 1 is a delay in the detachment of the umbilical cord stump after birth. In newborns, the stump normally falls off within the first two weeks of life; but, in infants with leukocyte adhesion deficiency type 1, this separation usually occurs at three weeks or later. In addition, affected infants often have inflammation of the umbilical cord stump (omphalitis) due to a bacterial infection.  In leukocyte adhesion deficiency type 1, bacterial and fungal infections most commonly occur on the skin and mucous membranes such as the moist lining of the nose and mouth. In childhood, people with this condition develop severe inflammation of the gums (gingivitis) and other tissue around the teeth (periodontitis), which often results in the loss of both primary and permanent teeth. These infections often spread to cover a large area. A hallmark of leukocyte adhesion deficiency type 1 is the lack of pus formation at the sites of infection. In people with this condition, wounds are slow to heal, which can lead to additional infection.  Life expectancy in individuals with leukocyte adhesion deficiency type 1 is often severely shortened. Due to repeat infections, affected individuals may not survive past infancy.

Topic: leukocyte adhesion deficiency type 1
Question: What are the genetic changes related to leukocyte adhesion deficiency type 1 ?
Answer: Mutations in the ITGB2 gene cause leukocyte adhesion deficiency type 1. This gene provides instructions for making one part (the 2 subunit) of at least four different proteins known as 2 integrins. Integrins that contain the 2 subunit are found embedded in the membrane that surrounds white blood cells (leukocytes). These integrins help leukocytes gather at sites of infection or injury, where they contribute to the immune response. 2 integrins recognize signs of inflammation and attach (bind) to proteins called ligands on the lining of blood vessels. This binding leads to linkage (adhesion) of the leukocyte to the blood vessel wall. Signaling through the 2 integrins triggers the transport of the attached leukocyte across the blood vessel wall to the site of infection or injury.  ITGB2 gene mutations that cause leukocyte adhesion deficiency type 1 lead to the production of a 2 subunit that cannot bind with other subunits to form 2 integrins. Leukocytes that lack these integrins cannot attach to the blood vessel wall or cross the vessel wall to contribute to the immune response. As a result, there is a decreased response to injury and foreign invaders, such as bacteria and fungi, resulting in frequent infections, delayed wound healing, and other signs and symptoms of this condition.

Topic: Charcot-Marie-Tooth disease
Question: What are the genetic changes related to Charcot-Marie-Tooth disease ?
Answer: Charcot-Marie-Tooth disease is caused by mutations in many different genes. These genes provide instructions for making proteins that are involved in the function of peripheral nerves in the feet, legs, and hands. The gene mutations that cause Charcot-Marie-Tooth disease affect the function of the proteins in ways that are not fully understood; however, they likely impair axons, which transmit nerve impulses, or affect the specialized cells that produce myelin. As a result, peripheral nerve cells slowly lose the ability to stimulate the muscles and to transmit sensory signals to the brain.  The list of genes associated with Charcot-Marie-Tooth disease continues to grow as researchers study this disorder. Different mutations within a particular gene may cause signs and symptoms of differing severities or lead to different types of Charcot-Marie-Tooth disease.  CMT1 is caused by mutations in the following genes: PMP22 (CMT1A and CMT1E), MPZ (CMT1B), LITAF (CMT1C), EGR2 (CMT1D), and NEFL (CMT1F).  CMT2 can result from alterations in many genes, including MFN2 and KIF1B (CMT2A); RAB7A (CMT2B); LMNA (CMT2B1); TRPV4 (CMT2C); BSCL2 and GARS (CMT2D); NEFL (CMT2E); HSPB1 (CMT2F); MPZ (CMT2I and CMT2J); GDAP1 (CMT2K); and HSPB8 (CMT2L). Certain DNM2 gene mutations also cause a form of CMT2.  CMT4 is caused by mutations in the following genes: GDAP1 (CMT4A), MTMR2 (CMT4B1), SBF2 (CMT4B2), SH3TC2 (CMT4C), NDRG1 (CMT4D), EGR2 (CMT4E), PRX (CMT4F), FGD4 (CMT4H), and FIG4 (CMT4J).  Intermediate forms of the disorder can be caused by alterations in genes including DNM2, MPZ, YARS, and GDAP1. CMTX is caused by mutations in genes including GJB1 (CMTX1) and PRPS1 (CMTX5). Mutations in additional genes, some of which have not been identified, also cause various forms of Charcot-Marie-Tooth disease.

Topic: Charcot-Marie-Tooth disease
Question: Is Charcot-Marie-Tooth disease inherited ?
Answer: The pattern of inheritance varies with the type of Charcot-Marie-Tooth disease. CMT1, most cases of CMT2, and most intermediate forms are inherited in an autosomal dominant pattern. This pattern of inheritance means that one copy of the altered gene in each cell is sufficient to cause the disorder. In most cases, an affected person has one affected parent.  CMT4, a few CMT2 subtypes, and some intermediate forms are inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show signs and symptoms of the condition.  CMTX is inherited in an X-linked dominant pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome. The inheritance is dominant if one copy of the altered gene is sufficient to cause the condition. In most cases, affected males, who have the alteration on their only copy of the X chromosome, experience more severe symptoms of the disorder than females, who have two X chromosomes. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. All daughters of affected men will have one altered X chromosome, but they may only have mild symptoms of the disorder.  Some cases of Charcot-Marie-Tooth disease result from a new mutation and occur in people with no history of the disorder in their family.

Topic: Griscelli syndrome
Question: What is (are) Griscelli syndrome ?
Answer: Griscelli syndrome is an inherited condition characterized by unusually light (hypopigmented) skin and light silvery-gray hair starting in infancy. Researchers have identified three types of this disorder, which are distinguished by their genetic cause and pattern of signs and symptoms.  Griscelli syndrome type 1 involves severe problems with brain function in addition to the distinctive skin and hair coloring. Affected individuals typically have delayed development, intellectual disability, seizures, weak muscle tone (hypotonia), and eye and vision abnormalities. Another condition called Elejalde disease has many of the same signs and symptoms, and some researchers have proposed that Griscelli syndrome type 1 and Elejalde disease are actually the same disorder.  People with Griscelli syndrome type 2 have immune system abnormalities in addition to having hypopigmented skin and hair. Affected individuals are prone to recurrent infections. They also develop an immune condition called hemophagocytic lymphohistiocytosis (HLH), in which the immune system produces too many activated immune cells called T-lymphocytes and macrophages (histiocytes). Overactivity of these cells can damage organs and tissues throughout the body, causing life-threatening complications if the condition is untreated. People with Griscelli syndrome type 2 do not have the neurological abnormalities of type 1.  Unusually light skin and hair coloring are the only features of Griscelli syndrome type 3. People with this form of the disorder do not have neurological abnormalities or immune system problems.
