Question: What are the genetic changes related to galactosemia ?
Answer: Mutations in the GALT, GALK1, and GALE genes cause galactosemia. These genes provide instructions for making enzymes that are essential for processing galactose obtained from the diet. These enzymes break down galactose into another simple sugar, glucose, and other molecules that the body can store or use for energy.  Mutations in the GALT gene cause classic galactosemia (type I). Most of these genetic changes almost completely eliminate the activity of the enzyme produced from the GALT gene, preventing the normal processing of galactose and resulting in the life-threatening signs and symptoms of this disorder. Another GALT gene mutation, known as the Duarte variant, reduces but does not eliminate the activity of the enzyme. People with the Duarte variant tend to have much milder features of galactosemia.  Galactosemia type II results from mutations in the GALK1 gene, while mutations in the GALE gene underlie galactosemia type III. Like the enzyme produced from the GALT gene, the enzymes made from the GALK1 and GALE genes play important roles in processing galactose. A shortage of any of these critical enzymes allows galactose and related compounds to build up to toxic levels in the body. The accumulation of these substances damages tissues and organs, leading to the characteristic features of galactosemia.

Question: Is galactosemia inherited ?
Answer: 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.

Question: What is (are) microvillus inclusion disease ?
Answer: Microvillus inclusion disease is a condition characterized by chronic, watery, life-threatening diarrhea typically beginning in the first hours to days of life. Rarely, the diarrhea starts around age 3 or 4 months. Food intake increases the frequency of diarrhea.  Microvillus inclusion disease prevents the absorption of nutrients from food during digestion, resulting in malnutrition and dehydration. Affected infants often have difficulty gaining weight and growing at the expected rate (failure to thrive), developmental delay, liver and kidney problems, and thinning of the bones (osteoporosis). Some affected individuals develop cholestasis, which is a reduced ability to produce and release a digestive fluid called bile. Cholestasis leads to irreversible liver disease (cirrhosis).  In individuals with microvillus inclusion disease, lifelong nutritional support is needed and given through intravenous feedings (parenteral nutrition). Even with nutritional supplementation, most children with microvillus inclusion disease do not survive beyond childhood.  A variant of microvillus inclusion disease with milder diarrhea often does not require full-time parenteral nutrition. Individuals with the variant type frequently live past childhood.

Question: What are the genetic changes related to microvillus inclusion disease ?
Answer: Mutations in the MYO5B gene cause microvillus inclusion disease. The MYO5B gene provides instructions for making a protein called myosin Vb. This protein helps to determine the position of various components within cells (cell polarity). Myosin Vb also plays a role in moving components from the cell membrane to the interior of the cell for recycling.  MYO5B gene mutations that cause microvillus inclusion disease result in a decrease or absence of myosin Vb function. In cells that line the small intestine (enterocytes), a lack of myosin Vb function changes the cell polarity. As a result, enterocytes cannot properly form structures called microvilli, which normally project like small fingers from the surface of the cells and absorb nutrients and fluids from food as it passes through the intestine. Inside affected enterocytes, small clumps of abnormal microvilli mix with misplaced digestive proteins to form microvillus inclusions, which contribute to the dysfunction of enterocytes. Disorganized enterocytes with poorly formed microvilli reduce the intestine's ability to take in nutrients. The inability to absorb nutrients and fluids during digestion leads to recurrent diarrhea, malnutrition, and dehydration in individuals with microvillus inclusion disease.  Some people with the signs and symptoms of microvillus inclusion disease do not have mutations in the MYO5B gene. These cases may be variants of microvillus inclusion disease. Studies suggest that mutations in other genes can cause these cases, but the causes are usually unknown.

Question: What is (are) Hermansky-Pudlak syndrome ?
Answer: Hermansky-Pudlak syndrome is a disorder characterized by a condition called oculocutaneous albinism, which causes abnormally light coloring (pigmentation) of the skin, hair, and eyes. Affected individuals typically have fair skin and white or light-colored hair. People with this disorder have a higher than average risk of skin damage and skin cancers caused by long-term sun exposure. Oculocutaneous albinism reduces pigmentation of the colored part of the eye (iris) and the light-sensitive tissue at the back of the eye (retina). Reduced vision, rapid and involuntary eye movements (nystagmus), and increased sensitivity to light (photophobia) are also common in oculocutaneous albinism. In Hermansky-Pudlak syndrome, these vision problems usually remain stable after early childhood.  People with Hermansky-Pudlak syndrome also have problems with blood clotting (coagulation) that lead to easy bruising and prolonged bleeding.  Some individuals with Hermansky-Pudlak syndrome develop breathing problems due to a lung disease called pulmonary fibrosis, which causes scar tissue to form in the lungs. The symptoms of pulmonary fibrosis usually appear during an individual's early thirties and rapidly worsen. Individuals with Hermansky-Pudlak syndrome who develop pulmonary fibrosis often do not live for more than a decade after they begin to experience breathing problems.  Other, less common features of Hermansky-Pudlak syndrome include inflammation of the large intestine (granulomatous colitis) and kidney failure.  There are nine different types of Hermansky-Pudlak syndrome, which can be distinguished by their signs and symptoms and underlying genetic cause. Types 1 and 4 are the most severe forms of the disorder. Types 1, 2, and 4 are the only types associated with pulmonary fibrosis. Individuals with type 3, 5, or 6 have the mildest symptoms. Little is known about the signs, symptoms, and severity of types 7, 8, and 9.

Question: How many people are affected by Hermansky-Pudlak syndrome ?
Answer: Hermansky-Pudlak syndrome is a rare disorder in most populations and is estimated to affect 1 in 500,000 to 1,000,000 individuals worldwide. Type 1 is more common in Puerto Rico, particularly in the northwestern part of the island where about 1 in 1,800 people are affected. Type 3 is common in people from central Puerto Rico. Groups of affected individuals have been identified in many other regions, including India, Japan, the United Kingdom, and Western Europe.

Question: What are the genetic changes related to Hermansky-Pudlak syndrome ?
Answer: At least nine genes are associated with Hermansky-Pudlak syndrome. These genes provide instructions for making proteins that are used to make four distinct protein complexes. These protein complexes play a role in the formation and movement (trafficking) of a group of cell structures called lysosome-related organelles (LROs). LROs are very similar to compartments within the cell called lysosomes, which digest and recycle materials. However, LROs perform specialized functions and are found only in certain cell types. LROs have been identified in pigment-producing cells (melanocytes), blood-clotting cells (platelets), and lung cells.  Mutations in the genes associated with Hermansky-Pudlak syndrome prevent the formation of LROs or impair the functioning of these cell structures. In general, mutations in genes that involve the same protein complex cause similar signs and symptoms. People with this syndrome have oculocutaneous albinism because the LROs within melanocytes cannot produce and distribute the substance that gives skin, hair, and eyes their color (melanin). Bleeding problems are caused by the absence of LROs within platelets, which affects the ability of platelets to stick together and form a blood clot. Mutations in some of the genes that cause Hermansky-Pudlak syndrome affect the normal functioning of LROs in lung cells, leading to pulmonary fibrosis.  Mutations in the HPS1 gene cause approximately 75 percent of the Hermansky-Pudlak syndrome cases from Puerto Rico. About 45 percent of affected individuals from other populations have mutations in the HPS1 gene. Mutations in the HPS3 gene are found in about 25 percent of affected people from Puerto Rico and in approximately 20 percent of affected individuals from other areas. The other genes associated with Hermansky-Pudlak syndrome each account for a small percentage of cases of this condition.  In some people with Hermansky-Pudlak syndrome, the genetic cause of the disorder is unknown.

Question: What is (are) incontinentia pigmenti ?
Answer: Incontinentia pigmenti is a condition that can affect many body systems, particularly the skin. This condition occurs much more often in females than in males.  Incontinentia pigmenti is characterized by skin abnormalities that evolve throughout childhood and young adulthood. Many affected infants have a blistering rash at birth and in early infancy, which heals and is followed by the development of wart-like skin growths. In early childhood, the skin develops grey or brown patches (hyperpigmentation) that occur in a swirled pattern. These patches fade with time, and adults with incontinentia pigmenti usually have lines of unusually light-colored skin (hypopigmentation) on their arms and legs.  Other signs and symptoms of incontinentia pigmenti can include hair loss (alopecia) affecting the scalp and other parts of the body, dental abnormalities (such as small teeth or few teeth), eye abnormalities that can lead to vision loss, and lined or pitted fingernails and toenails. Most people with incontinentia pigmenti have normal intelligence; however, this condition may affect the brain. Associated problems can include delayed development or intellectual disability, seizures, and other neurological problems.

Question: What are the genetic changes related to incontinentia pigmenti ?
Answer: Mutations in the IKBKG gene cause incontinentia pigmenti. The IKBKG gene provides instructions for making a protein that helps regulate nuclear factor-kappa-B. Nuclear factor-kappa-B is a group of related proteins that helps protect cells from self-destructing (undergoing apoptosis) in response to certain signals.  About 80 percent of affected individuals have a mutation that deletes some genetic material from the IKBKG gene. This deletion probably leads to the production of an abnormally small, nonfunctional version of the IKBKG protein. Other people with incontinentia pigmenti have mutations that prevent the production of any IKBKG protein. Without this protein, nuclear factor-kappa-B is not regulated properly, and cells are more sensitive to signals that trigger them to self-destruct. Researchers believe that this abnormal cell death leads to the signs and symptoms of incontinentia pigmenti.

Question: Is incontinentia pigmenti inherited ?
Answer: This condition is inherited in an X-linked dominant pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In females (who have two X chromosomes), a mutation in one of the two copies of the gene in each cell is sufficient to cause the disorder. Some cells produce a normal amount of IKBKG protein and other cells produce none. The resulting imbalance in cells producing this protein leads to the signs and symptoms of incontinentia pigmenti.  In males (who have only one X chromosome), most IKBKG mutations result in a total loss of the IKBKG protein. A lack of this protein appears to be lethal early in development, so few males are born with incontinentia pigmenti. Affected males who survive may have an IKBKG mutation with relatively mild effects, an IKBKG mutation in only some of the body's cells (mosaicism), or an extra copy of the X chromosome in each cell.  Some people with incontinentia pigmenti inherit an IKBKG 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.

Question: What is (are) Cornelia de Lange syndrome ?
Answer: Cornelia de Lange syndrome is a developmental disorder that affects many parts of the body. The features of this disorder vary widely among affected individuals and range from relatively mild to severe.  Cornelia de Lange syndrome is characterized by slow growth before and after birth leading to short stature; intellectual disability that is usually moderate to severe; and abnormalities of bones in the arms, hands, and fingers. Most people with Cornelia de Lange syndrome also have distinctive facial features, including arched eyebrows that often meet in the middle (synophrys), long eyelashes, low-set ears, small and widely spaced teeth, and a small and upturned nose. Many affected individuals also have behavior problems similar to autism, a developmental condition that affects communication and social interaction.  Additional signs and symptoms of Cornelia de Lange syndrome can include excessive body hair (hypertrichosis), an unusually small head (microcephaly), hearing loss, and problems with the digestive tract. Some people with this condition are born with an opening in the roof of the mouth called a cleft palate. Seizures, heart defects, and eye problems have also been reported in people with this condition.

Question: How many people are affected by Cornelia de Lange syndrome ?
Answer: Although the exact incidence is unknown, Cornelia de Lange syndrome likely affects 1 in 10,000 to 30,000 newborns. The condition is probably underdiagnosed because affected individuals with mild or uncommon features may never be recognized as having Cornelia de Lange syndrome.

Question: What are the genetic changes related to Cornelia de Lange syndrome ?
Answer: Cornelia de Lange syndrome can result from mutations in at least five genes: NIPBL, SMC1A, HDAC8, RAD21, and SMC3. Mutations in the NIPBL gene have been identified in more than half of all people with this condition; mutations in the other genes are much less common.  The proteins produced from all five genes contribute to the structure or function of the cohesin complex, a group of proteins with an important role in directing development before birth. Within cells, the cohesin complex helps regulate the structure and organization of chromosomes, stabilize cells' genetic information, and repair damaged DNA. The cohesin complex also regulates the activity of certain genes that guide the development of limbs, face, and other parts of the body.  Mutations in the NIPBL, SMC1A, HDAC8, RAD21, and SMC3 genes cause Cornelia de Lange syndrome by impairing the function of the cohesin complex, which disrupts gene regulation during critical stages of early development.  The features of Cornelia de Lange syndrome vary widely, and the severity of the disorder can differ even in individuals with the same gene mutation. Researchers suspect that additional genetic or environmental factors may be important for determining the specific signs and symptoms in each individual. In general, SMC1A, RAD21, and SMC3 gene mutations cause milder signs and symptoms than NIPBL gene mutations. Mutations in the HDAC8 gene cause a somewhat different set of features, including delayed closure of the "soft spot" on the head (the anterior fontanelle) in infancy, widely spaced eyes, and dental abnormalities. Like affected individuals with NIPBL gene mutations, those with HDAC8 gene mutations may have significant intellectual disability.  In about 30 percent of cases, the cause of Cornelia de Lange syndrome is unknown. Researchers are looking for additional changes in the five known genes, as well as mutations in other genes, that may cause this condition.

Question: Is Cornelia de Lange syndrome inherited ?
Answer: When Cornelia de Lange syndrome is caused by mutations in the NIPBL, RAD21, or SMC3 gene, the condition is considered to have an autosomal dominant pattern of inheritance. Autosomal dominant inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases result from new gene mutations and occur in people with no history of the condition in their family.  When Cornelia de Lange syndrome is caused by mutations in the HDAC8 or SMC1A gene, the condition has an X-linked dominant pattern of inheritance. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. Studies of X-linked Cornelia de Lange syndrome indicate that one copy of the altered gene in each cell may be sufficient to cause the condition. Unlike X-linked recessive conditions, in which males are more frequently affected or experience more severe symptoms than females, X-linked dominant Cornelia de Lange syndrome appears to affect males and females similarly. Most cases result from new mutations in the HDAC8 or SMC1A gene and occur in people with no history of the condition in their family.
