Question:
What are the genetic changes related to spondylocostal dysostosis ?

Answer:
Mutations in at least four genes are known to cause spondylocostal dysostosis: Mutations in the DLL3 gene cause spondylocostal dysostosis type 1; mutations in the MESP2 gene cause spondylocostal dysostosis type 2; mutations in the LFNG gene cause spondylocostal dysostosis type 3; and mutations in the HES7 gene cause spondylocostal dysostosis type 4. The genetic cause of AD spondylocostal dysostosis is unknown.  The DLL3, MESP2, LFNG, and HES7 genes play a role in the Notch signaling pathway, an important pathway in embryonic development. One of the functions of the Notch pathway is separating future vertebrae from one another during early development, a process called somite segmentation. When this pathway is disrupted, somite segmentation does not occur properly, resulting in the malformation and fusion of the bones of the spine and ribs seen in spondylocostal dysostosis.  Mutations in the four identified genes account for approximately 25 percent of diagnosed spondylocostal dysostosis. Researchers suggest that additional genes in the Notch signaling pathway might also be involved.
Question:
Is spondylocostal dysostosis inherited ?

Answer:
Spondylocostal dysostosis can have different inheritance patterns. Types 1, 2, 3, and 4 are 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. AD spondylocostal dysostosis is inherited in an autosomal dominant pattern. Autosomal dominant inheritance means that one copy of an altered gene in each cell is sufficient to cause the disorder, although in these cases no causative genes have been identified. The signs and symptoms of spondylocostal dysostosis are typically more severe with autosomal recessive inheritance.

Question:
What is (are) lamellar ichthyosis ?

Answer:
Lamellar ichthyosis is a condition that mainly affects the skin. Infants with this condition are typically born with a tight, clear sheath covering their skin called a collodion membrane. This membrane usually dries and peels off during the first few weeks of life, and then it becomes obvious that affected babies have scaly skin, and eyelids and lips that are turned outward. People with lamellar ichthyosis typically have large, dark, plate-like scales covering their skin on most of their body. Infants with lamellar ichthyosis may develop infections, an excessive loss of fluids (dehydration), and respiratory problems. Affected individuals may also have hair loss (alopecia), abnormally formed fingernails and toenails (nail dystrophy), a decreased ability to sweat (hypohidrosis), an increased sensitivity to heat, and a thickening of the skin on the palms of the hands and soles of the feet (keratoderma). Less frequently, affected individuals have reddened skin (erythema) and joint deformities (contractures).
Question:
How many people are affected by lamellar ichthyosis ?

Answer:
Lamellar ichthyosis is estimated to affect 1 in 100,000 individuals in the United States. This condition is more common in Norway, where an estimated 1 in 91,000 individuals are affected.
Question:
What are the genetic changes related to lamellar ichthyosis ?

Answer:
Mutations in one of many genes can cause lamellar ichthyosis. These genes provide instructions for making proteins that are found in the outermost layer of the skin (the epidermis). The skin abnormalities associated with lamellar ichthyosis disrupt the normal formation of the epidermis, resulting in impaired regulation of body temperature, water retention, and resistance to infections.  Mutations in the TGM1 gene are responsible for approximately 90 percent of cases of lamellar ichthyosis. The TGM1 gene provides instructions for making an enzyme called transglutaminase 1. This enzyme is involved in the formation of the cornified cell envelope, which is a structure that surrounds skin cells and helps form a protective barrier between the body and its environment. TGM1 gene mutations lead to severely reduced or absent enzyme production, which prevents the formation of the cornified cell envelope.  Mutations in other genes associated with lamellar ichthyosis are each responsible for only a small percentage of cases. In some people with lamellar ichthyosis, the cause of the disorder is unknown. Researchers have identified multiple chromosome regions that contain genes that may be associated with lamellar ichthyosis, although the specific genes have not been identified.
Question:
Is lamellar ichthyosis 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) narcolepsy ?

Answer:
Narcolepsy is a chronic sleep disorder that disrupts the normal sleep-wake cycle. Although this condition can appear at any age, it most often begins in adolescence.  Narcolepsy is characterized by excessive daytime sleepiness. Affected individuals feel tired during the day, and several times a day they may experience an overwhelming urge to sleep. "Sleep attacks" can occur at unusual times, such as during a meal or in the middle of a conversation. They last from a few seconds to a few minutes and often lead to a longer nap, after which affected individuals wake up feeling refreshed.  Another common feature of narcolepsy is cataplexy, which is a sudden loss of muscle tone in response to strong emotion (such as laughing, surprise, or anger). These episodes of muscle weakness can cause an affected person to slump over or fall, which occasionally leads to injury. Episodes of cataplexy usually last just a few seconds, and they may occur from several times a day to a few times a year. Most people diagnosed with narcolepsy also have cataplexy. However, some do not, which has led researchers to distinguish two major forms of the condition: narcolepsy with cataplexy and narcolepsy without cataplexy.  Narcolepsy also affects nighttime sleep. Most affected individuals have trouble sleeping for more than a few hours at night. They often experience vivid hallucinations while falling asleep (hypnogogic hallucinations) or while waking up (hypnopompic hallucinations). Affected individuals often have realistic and distressing dreams, and they may act out their dreams by moving excessively or talking in their sleep. Many people with narcolepsy also experience sleep paralysis, which is an inability to move or speak for a short period while falling asleep or awakening. The combination of hallucinations, vivid dreams, and sleep paralysis is often frightening and unpleasant for affected individuals.  Some people with narcolepsy have all of the major features of the disorder, while others have only one or two. Most of the signs and symptoms persist throughout life, although episodes of cataplexy may become less frequent with age and treatment.
Question:
How many people are affected by narcolepsy ?

Answer:
Narcolepsy affects about 1 in 2,000 people in the United States and Western Europe. However, the disorder is likely underdiagnosed, particularly in people with mild symptoms. Worldwide, narcolepsy appears to be most common in Japan, where it affects an estimated 1 in 600 people.
Question:
What are the genetic changes related to narcolepsy ?

Answer:
Narcolepsy probably results from a combination of genetic and environmental factors, some of which have been identified, but many of which remain unknown.  In most cases of narcolepsy with cataplexy, and in some cases without cataplexy, sleep abnormalities result from a loss of particular brain cells (neurons) in a part of the brain called the hypothalamus. These cells normally produce chemicals called hypocretins (also known as orexins), which have many important functions in the body. In particular, hypocretins regulate the daily sleep-wake cycle. It is unclear what triggers the death of hypocretin-producing neurons in people with narcolepsy, although evidence increasingly points to an abnormality of the immune system.  Researchers have identified changes in several genes that influence the risk of developing narcolepsy. The most well-studied of these genes is HLA-DQB1, which provides instructions for making part of a protein that plays an important role in the immune system. The HLA-DQB1 gene is part of a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders (such as viruses and bacteria). The HLA-DQB1 gene has many different normal variations, allowing each person's immune system to react to a wide range of foreign proteins. A variation of the HLA-DQB1 gene called HLA-DQB1*06:02 has been strongly associated with narcolepsy, particularly in people who also have cataplexy and a loss of hypocretins. Most people with narcolepsy have the HLA-DQB1*06:02 variation, and many also have specific versions of other, closely related HLA genes. It is unclear how these genetic changes influence the risk of developing the condition.  Variations in several additional genes have also been associated with narcolepsy. Many of these genes are thought to play roles in immune system function. However, variations in these genes probably make only a small contribution to the overall risk of developing narcolepsy. Other genetic and environmental factors are also likely to influence a person's chances of developing this disorder. For example, studies suggest that bacterial or viral infections such as strep throat (streptococcus), colds, and influenza may be involved in triggering narcolepsy in people who are at risk.
Question:
Is narcolepsy inherited ?

Answer:
Most cases of narcolepsy are sporadic, which means they occur in people with no history of the disorder in their family. A small percentage of all cases have been reported to run in families; however, the condition does not have a clear pattern of inheritance. First-degree relatives (parents, siblings, and children) of people with narcolepsy with cataplexy have a 40 times greater risk of developing the condition compared with people in the general population.

Question:
What is (are) retinal arterial macroaneurysm with supravalvular pulmonic stenosis ?

Answer:
Retinal arterial macroaneurysm with supravalvular pulmonic stenosis (RAMSVPS) is a disorder that affects blood vessels in the eyes and heart. The condition generally becomes apparent in infancy or childhood.  RAMSVPS damages the arteries in the light-sensitive tissue at the back of the eye (the retina). These arteries gradually develop multiple small bulges called beading. Eventually, larger bulges in the blood vessel walls (macroaneurysms) occur. These macroaneurysms can tear (rupture), leading to bleeding that can spread into other areas of the eye and cause vision loss.  People with RAMSVPS also have a heart condition called supravalvular pulmonic stenosis. Pulmonic stenosis is a narrowing that affects the pulmonic valve between the heart and the lungs. The term "supravalvular" means that the narrowing occurs just above the valve, in a blood vessel called the pulmonary artery. Supravalvular pulmonic stenosis impairs blood flow into the lungs, where blood normally picks up oxygen for distribution to cells and tissues throughout the body. As a result, less oxygen is carried through the bloodstream, leading to signs and symptoms that include shortness of breath; a rapid heartbeat; fatigue; and swelling in the face, feet, or abdomen.
Question:
How many people are affected by retinal arterial macroaneurysm with supravalvular pulmonic stenosis ?

Answer:
RAMSVPS is a rare disorder. Only a small number of affected individuals and families, all from Saudi Arabia, have been described in the medical literature.
Question:
What are the genetic changes related to retinal arterial macroaneurysm with supravalvular pulmonic stenosis ?

Answer:
RAMSVPS is caused by a mutation in the IGFBP7 gene. This gene provides instructions for making a protein called insulin-like growth factor-binding protein 7 (IGFBP7). The IGFBP7 protein is active in the lining of blood vessels (the vascular endothelium). It is thought to help stop a pathway called BRAF signaling, which is involved in directing cell growth.  The IGFBP7 gene mutation that causes RAMSVPS results in an abnormally short IGFBP7 protein that does not function properly. Without normally functioning IGFBP7 protein to control BRAF signaling, this signaling is increased. It is unknown how this increase is related to the specific blood vessel abnormalities that occur in RAMSVPS, or why these abnormalities are confined to the eyes and the pulmonary artery. Researchers suggest that differences in normal levels of IGFBP7 protein in various parts of the body or the presence of other proteins with a similar function in different tissues may account for the specific signs and symptoms of this disorder.
Question:
Is retinal arterial macroaneurysm with supravalvular pulmonic stenosis 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) X-linked severe combined immunodeficiency ?

Answer:
X-linked severe combined immunodeficiency (SCID) is an inherited disorder of the immune system that occurs almost exclusively in males. Boys with X-linked SCID are prone to recurrent and persistent infections because they lack the necessary immune cells to fight off certain bacteria, viruses, and fungi. Many infants with X-linked SCID develop chronic diarrhea, a fungal infection called thrush, and skin rashes. Affected individuals also grow more slowly than other children. Without treatment, males with X-linked SCID usually do not live beyond infancy.
Question:
How many people are affected by X-linked severe combined immunodeficiency ?

Answer:
X-linked SCID is the most common form of severe combined immunodeficiency. Its exact incidence is unknown, but the condition probably affects at least 1 in 50,000 to 100,000 newborns.
Question:
What are the genetic changes related to X-linked severe combined immunodeficiency ?

Answer:
Mutations in the IL2RG gene cause X-linked SCID. The IL2RG gene provides instructions for making a protein that is critical for normal immune system function. This protein is necessary for the growth and maturation of developing immune system cells called lymphocytes. Lymphocytes defend the body against potentially harmful invaders, make antibodies, and help regulate the entire immune system. Mutations in the IL2RG gene prevent these cells from developing and functioning normally. Without functional lymphocytes, the body is unable to fight off infections.
Question:
Is X-linked severe combined immunodeficiency 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.

Question:
What is (are) fibrochondrogenesis ?

Answer:
Fibrochondrogenesis is a very severe disorder of bone growth. Affected infants have a very narrow chest, which prevents the lungs from developing normally. Most infants with this condition are stillborn or die shortly after birth from respiratory failure. However, some affected individuals have lived into childhood.  Fibrochondrogenesis is characterized by short stature (dwarfism) and other skeletal abnormalities. Affected individuals have shortened long bones in the arms and legs that are unusually wide at the ends (described as dumbbell-shaped). People with this condition also have a narrow chest with short, wide ribs and a round and prominent abdomen. The bones of the spine (vertebrae) are flattened (platyspondyly) and have a characteristic pinched or pear shape that is noticeable on x-rays. Other skeletal abnormalities associated with fibrochondrogenesis include abnormal curvature of the spine and underdeveloped hip (pelvic) bones.  People with fibrochondrogenesis also have distinctive facial features. These include prominent eyes, low-set ears, a small mouth with a long upper lip, and a small chin (micrognathia). Affected individuals have a relatively flat-appearing midface, particularly a small nose with a flat nasal bridge and nostrils that open to the front rather than downward (anteverted nares). Vision problems, including severe nearsightedness (high myopia) and clouding of the lens of the eye (cataract), are common in those who survive infancy. Most affected individuals also have sensorineural hearing loss, which is caused by abnormalities of the inner ear.
Question:
How many people are affected by fibrochondrogenesis ?

Answer:
Fibrochondrogenesis appears to be a rare disorder. About 20 affected individuals have been described in the medical literature.
Question:
What are the genetic changes related to fibrochondrogenesis ?

Answer:
Fibrochondrogenesis can result from mutations in the COL11A1 or COL11A2 gene. These genes provide instructions for making components of type XI collagen, which is a complex molecule that gives structure and strength to the connective tissues that support the body's joints and organs. Specifically, type XI collagen is found in cartilage, a tough but flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears. Type XI collagen is also part of the inner ear; the vitreous, which is the clear gel that fills the eyeball; and the nucleus pulposus, which is the center portion of the discs between vertebrae.  Mutations in the COL11A1 or COL11A2 gene impair the assembly of type XI collagen, in most cases leading to the production of abnormal collagen molecules. The defective collagen weakens connective tissues, impairing the formation of bones throughout the skeleton and causing changes in the eye and inner ear that lead to vision and hearing problems.
Question:
Is fibrochondrogenesis inherited ?

Answer:
Fibrochondrogenesis is generally 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 usually do not show signs and symptoms of the condition. In a few reported cases, parents of children with fibrochondrogenesis have had mild features that may be related to the condition, including slightly short stature, myopia, cataracts, joint pain, and hearing loss.  In at least one case of fibrochondrogenesis caused by a COL11A2 gene mutation, the condition was inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In this case, the condition resulted from a new (de novo) mutation in the gene that occurred during the formation of reproductive cells (eggs or sperm) in one of the affected individual's parents. There was no history of the disorder in the family.
