What is (are) hereditary hypophosphatemic rickets ? 
 Hereditary hypophosphatemic rickets is a disorder related to low levels of phosphate in the blood (hypophosphatemia). Phosphate is a mineral that is essential for the normal formation of bones and teeth.  In most cases, the signs and symptoms of hereditary hypophosphatemic rickets begin in early childhood. The features of the disorder vary widely, even among affected members of the same family. Mildly affected individuals may have hypophosphatemia without other signs and symptoms. More severely affected children experience slow growth and are shorter than their peers. They develop bone abnormalities that can interfere with movement and cause bone pain. The most noticeable of these abnormalities are bowed legs or knock knees (a condition in which the lower legs are positioned at an outward angle). These abnormalities become apparent with weight-bearing activities such as walking. If untreated, they tend to worsen with time.  Other signs and symptoms of hereditary hypophosphatemic rickets can include premature fusion of the skull bones (craniosynostosis) and dental abnormalities. The disorder may also cause abnormal bone growth where ligaments and tendons attach to joints (enthesopathy). In adults, hypophosphatemia is characterized by a softening of the bones known as osteomalacia.  Researchers have described several forms of hereditary hypophosphatemic rickets, which are distinguished by their pattern of inheritance and genetic cause. The most common form of the disorder is known as X-linked hypophosphatemic rickets (XLH). It has an X-linked dominant pattern of inheritance. X-linked recessive, autosomal dominant, and autosomal recessive forms of the disorder are much rarer. The different inheritance patterns are described below.  Another rare type of the disorder is known as hereditary hypophosphatemic rickets with hypercalciuria (HHRH). In addition to hypophosphatemia, this condition is characterized by the excretion of high levels of calcium in the urine (hypercalciuria).
How many people are affected by hereditary hypophosphatemic rickets ? 
 X-linked hypophosphatemic rickets is the most common form of rickets that runs in families. It affects about 1 in 20,000 newborns. Each of the other forms of hereditary hypophosphatemic rickets has been identified in only a few families.
What are the genetic changes related to hereditary hypophosphatemic rickets ? 
 Hereditary hypophosphatemic rickets can result from mutations in several genes. Mutations in the PHEX gene, which are responsible for X-linked hypophosphatemic rickets, occur most frequently. Mutations in other genes cause the less common forms of the condition.  Hereditary hypophosphatemic rickets is characterized by a phosphate imbalance in the body. Among its many functions, phosphate plays a critical role in the formation and growth of bones in childhood and helps maintain bone strength in adults. Phosphate levels are controlled in large part by the kidneys. The kidneys normally excrete excess phosphate in urine, and they reabsorb this mineral into the bloodstream when more is needed. However, in people with hereditary hypophosphatemic rickets, the kidneys cannot reabsorb phosphate effectively and too much of this mineral is excreted from the body in urine. As a result, not enough phosphate is available in the bloodstream to participate in normal bone development and maintenance.  The genes associated with hereditary hypophosphatemic rickets are involved in maintaining the proper balance of phosphate. Many of these genes, including the PHEX gene, directly or indirectly regulate a protein called fibroblast growth factor 23 (produced from the FGF23 gene). This protein normally inhibits the kidneys' ability to reabsorb phosphate into the bloodstream. Gene mutations increase the production or reduce the breakdown of fibroblast growth factor 23. The resulting overactivity of this protein reduces phosphate reabsorption by the kidneys, leading to hypophosphatemia and the related features of hereditary hypophosphatemic rickets.
Is hereditary hypophosphatemic rickets inherited ? 
 Hereditary hypophosphatemic rickets can have several patterns of inheritance. When the condition results from mutations in the PHEX gene, it is inherited in an X-linked dominant pattern. The PHEX gene 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. In males (who have only one X chromosome), a mutation in the only copy of the gene in each cell causes the disorder. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.  Less commonly, hereditary hypophosphatemic rickets can have an X-linked recessive pattern of inheritance. This form of the condition is often called Dent disease. Like the PHEX gene, the gene associated with Dent disease is located on the X chromosome. In males, one altered copy of the gene in each cell is sufficient to cause the condition. In females, 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.  In a few families, hereditary hypophosphatemic rickets has had an autosomal dominant inheritance pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. The rare condition HHRH has an autosomal recessive pattern of inheritance, 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. However, some parents of children with HHRH have experienced hypercalcuria and kidney stones.

What is (are) Glanzmann thrombasthenia ? 
 Glanzmann thrombasthenia is a bleeding disorder that is characterized by prolonged or spontaneous bleeding starting from birth. People with Glanzmann thrombasthenia tend to bruise easily, have frequent nosebleeds (epistaxis), and may bleed from the gums. They may also develop red or purple spots on the skin caused by bleeding underneath the skin (petechiae) or swelling caused by bleeding within tissues (hematoma). Glanzmann thrombasthenia can also cause prolonged bleeding following injury, trauma, or surgery (including dental work). Women with this condition can have prolonged and sometimes abnormally heavy menstrual bleeding. Affected women also have an increased risk of excessive blood loss during pregnancy and childbirth.  About a quarter of individuals with Glanzmann thrombasthenia have bleeding in the gastrointestinal tract, which often occurs later in life. Rarely, affected individuals have bleeding inside the skull (intracranial hemorrhage) or joints (hemarthrosis).  The severity and frequency of the bleeding episodes in Glanzmann thrombasthenia can vary greatly among affected individuals, even in the same family. Spontaneous bleeding tends to become less frequent with age.
How many people are affected by Glanzmann thrombasthenia ? 
 Glanzmann thrombasthenia is estimated to affect 1 in one million individuals worldwide, but may be more common in certain groups, including those of Romani ethnicity, particularly people within the French Manouche community.
What are the genetic changes related to Glanzmann thrombasthenia ? 
 Mutations in the ITGA2B or ITGB3 gene cause Glanzmann thrombasthenia. These genes provide instructions for making the two parts (subunits) of a receptor protein called integrin alphaIIb/beta3 (IIb3). This protein is abundant on the surface of platelets. Platelets are small cell fragments that circulate in blood and are an essential component of blood clots. During clot formation, integrin IIb3 helps platelets bind together. Blood clots protect the body after injury by sealing off damaged blood vessels and preventing further blood loss.  ITGA2B or ITGB3 gene mutations result in a shortage (deficiency) of functional integrin IIb3. As a result, platelets cannot clump together to form a blood clot, leading to prolonged bleeding.  Three types of Glanzmann thrombasthenia have been classified according to the amount of integrin IIb3 that is available. People with type I (the most common type) have less than 5 percent of normal integrin IIb3 levels, people with type II have between 5 and 20 percent of normal integrin IIb3 levels, and people with the variant type have adequate integrin IIb3 levels but produce only nonfunctional integrin.  Some people with Glanzmann thrombasthenia do not have an identified mutation in either the ITGA2B or ITGB3 gene; the cause of the disorder in these individuals is unknown.
Is Glanzmann thrombasthenia 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.

What is (are) neuroferritinopathy ? 
 Neuroferritinopathy is a disorder in which iron gradually accumulates in the brain. Certain brain regions that help control movement (basal ganglia) are particularly affected. People with neuroferritinopathy have progressive problems with movement that begin at about age 40. These movement problems can include involuntary jerking motions (chorea), rhythmic shaking (tremor), difficulty coordinating movements (ataxia), or uncontrolled tensing of muscles (dystonia). Symptoms of the disorder may be more apparent on one side of the body than on the other. Affected individuals may also have difficulty swallowing (dysphagia) and speaking (dysarthria).  Intelligence is unaffected in most people with neuroferritinopathy, but some individuals develop a gradual decline in thinking and reasoning abilities (dementia). Personality changes such as reduced inhibitions and difficulty controlling emotions may also occur as the disorder progresses.
How many people are affected by neuroferritinopathy ? 
 The prevalence of neuroferritinopathy is unknown. Fewer than 100 individuals with this disorder have been reported.
What are the genetic changes related to neuroferritinopathy ? 
 Mutations in the FTL gene cause neuroferritinopathy. The FTL gene provides instructions for making the ferritin light chain, which is one part (subunit) of a protein called ferritin. Ferritin stores and releases iron in cells. Each ferritin molecule can hold as many as 4,500 iron atoms. This storage capacity allows ferritin to regulate the amount of iron in the cells and tissues.  Mutations in the FTL gene that cause neuroferritinopathy are believed to reduce ferritin's ability to store iron, resulting in the release of excess iron in nerve cells (neurons) of the brain. The cells may respond by producing more ferritin in an attempt to handle the free iron. Excess iron and ferritin accumulate in the brain, particularly in the basal ganglia, resulting in the movement problems and other neurological changes seen in neuroferritinopathy.
Is neuroferritinopathy inherited ? 
 This condition 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 most cases, an affected person inherits the mutation from one affected parent. Other cases may result from new mutations in the gene. These cases occur in people with no history of the disorder in their family.

What is (are) Diamond-Blackfan anemia ? 
 Diamond-Blackfan anemia is a disorder of the bone marrow. The major function of bone marrow is to produce new blood cells. In Diamond-Blackfan anemia, the bone marrow malfunctions and fails to make enough red blood cells, which carry oxygen to the body's tissues. The resulting shortage of red blood cells (anemia) usually becomes apparent during the first year of life. Symptoms of anemia include fatigue, weakness, and an abnormally pale appearance (pallor).  People with Diamond-Blackfan anemia have an increased risk of several serious complications related to their malfunctioning bone marrow. Specifically, they have a higher-than-average chance of developing myelodysplastic syndrome (MDS), which is a disorder in which immature blood cells fail to develop normally. Affected individuals also have an increased risk of developing certain cancers, including a cancer of blood-forming tissue known as acute myeloid leukemia (AML) and a type of bone cancer called osteosarcoma.  Approximately half of individuals with Diamond-Blackfan anemia have physical abnormalities. They may have an unusually small head size (microcephaly) and a low frontal hairline, along with distinctive facial features such as wide-set eyes (hypertelorism); droopy eyelids (ptosis); a broad, flat bridge of the nose; small, low-set ears; and a small lower jaw (micrognathia). Affected individuals may also have an opening in the roof of the mouth (cleft palate) with or without a split in the upper lip (cleft lip). They may have a short, webbed neck; shoulder blades which are smaller and higher than usual; and abnormalities of their hands, most commonly malformed or absent thumbs. About one-third of affected individuals have slow growth leading to short stature.  Other features of Diamond-Blackfan anemia may include eye problems such as clouding of the lens of the eyes (cataracts), increased pressure in the eyes (glaucoma), or eyes that do not look in the same direction (strabismus). Affected individuals may also have kidney abnormalities; structural defects of the heart; and, in males, the opening of the urethra on the underside of the penis (hypospadias).  The severity of Diamond-Blackfan anemia may vary, even within the same family. Increasingly, individuals with "non-classical" Diamond-Blackfan anemia have been identified. This form of the disorder typically has less severe symptoms that may include mild anemia beginning in adulthood.
How many people are affected by Diamond-Blackfan anemia ? 
 Diamond-Blackfan anemia affects approximately 5 to 7 per million liveborn infants worldwide.
What are the genetic changes related to Diamond-Blackfan anemia ? 
 Diamond-Blackfan anemia can be caused by mutations in the RPL5, RPL11, RPL35A, RPS7, RPS10, RPS17, RPS19, RPS24, and RPS26 genes. These genes provide instructions for making several of the approximately 80 different ribosomal proteins, which are components of cellular structures called ribosomes. Ribosomes process the cell's genetic instructions to create proteins.  Each ribosome is made up of two parts (subunits) called the large and small subunits. The RPL5, RPL11, and RPL35A genes provide instructions for making ribosomal proteins that are among those found in the large subunit. The ribosomal proteins produced from the RPS7, RPS10, RPS17, RPS19, RPS24, and RPS26 genes are among those found in the small subunit.  The specific functions of each ribosomal protein within these subunits are unclear. Some ribosomal proteins are involved in the assembly or stability of ribosomes. Others help carry out the ribosome's main function of building new proteins. Studies suggest that some ribosomal proteins may have other functions, such as participating in chemical signaling pathways within the cell, regulating cell division, and controlling the self-destruction of cells (apoptosis).  Mutations in any of the genes listed above are believed to affect the stability or function of the ribosomal proteins. Studies indicate that a shortage of functioning ribosomal proteins may increase the self-destruction of blood-forming cells in the bone marrow, resulting in anemia. Abnormal regulation of cell division or inappropriate triggering of apoptosis may contribute to the other health problems that affect some people with Diamond-Blackfan anemia.  Approximately 25 percent of individuals with Diamond-Blackfan anemia have identified mutations in the RPS19 gene. About another 25 to 35 percent of individuals with this disorder have identified mutations in the RPL5, RPL11, RPL35A, RPS7, RPS10, RPS17, RPS24, or RPS26 genes. In the remaining 40 to 50 percent of cases, the cause of the condition is unknown. Researchers suspect that other genes may also be associated with Diamond-Blackfan anemia.
Is Diamond-Blackfan anemia inherited ? 
 This condition 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 approximately 45 percent of cases, an affected person inherits the mutation from one affected parent. The remaining cases result from new mutations in the gene and occur in people with no history of the disorder in their family.

What is (are) 1p36 deletion syndrome ? 
 1p36 deletion syndrome is a disorder that typically causes severe intellectual disability. Most affected individuals do not speak, or speak only a few words. They may have temper tantrums, bite themselves, or exhibit other behavior problems. Most have structural abnormalities of the brain, and seizures occur in more than half of individuals with this disorder. Affected individuals usually have weak muscle tone (hypotonia) and swallowing difficulties (dysphagia).  People with 1p36 deletion syndrome have a small head that is also unusually short and wide in proportion to its size (microbrachycephaly). Affected individuals also have distinctive facial features including deep-set eyes with straight eyebrows; a sunken appearance of the middle of the face (midface hypoplasia); a broad, flat nose; a long area between the nose and mouth (philtrum); a pointed chin; and ears that are low-set, rotated backwards, and abnormally shaped.  People with 1p36 deletion syndrome may have vision or hearing problems. Some have abnormalities of the skeleton, heart, gastrointestinal system, kidneys, or genitalia.
How many people are affected by 1p36 deletion syndrome ? 
 1p36 deletion syndrome is believed to affect between 1 in 5,000 and 1 in 10,000 newborns. However, this may be an underestimate because some affected individuals are likely never diagnosed.
What are the genetic changes related to 1p36 deletion syndrome ? 
 1p36 deletion syndrome is caused by a deletion of genetic material from a specific region in the short (p) arm of chromosome 1. The signs and symptoms of 1p36 deletion syndrome are probably related to the loss of multiple genes in this region. The size of the deletion varies among affected individuals.
Is 1p36 deletion syndrome inherited ? 
 Most cases of 1p36 deletion syndrome are not inherited. They result from a chromosomal deletion that occurs as a random event during the formation of reproductive cells (eggs or sperm) or in early fetal development. Affected people typically have no history of the disorder in their family.  About 20 percent of people with 1p36 deletion syndrome inherit the chromosome with a deleted segment from an unaffected parent. In these cases, the parent carries a chromosomal rearrangement called a balanced translocation, in which no genetic material is gained or lost. Balanced translocations usually do not cause any health problems; however, they can become unbalanced as they are passed to the next generation. Children who inherit an unbalanced translocation can have a chromosomal rearrangement with extra or missing genetic material. Individuals with 1p36 deletion syndrome who inherit an unbalanced translocation are missing genetic material from the short arm of chromosome 1, which results in birth defects and other health problems characteristic of this disorder.

What is (are) Crouzonodermoskeletal syndrome ? 
 Crouzonodermoskeletal syndrome is a disorder characterized by the premature joining of certain bones of the skull (craniosynostosis) during development and a skin condition called acanthosis nigricans.  The signs and symptoms of Crouzonodermoskeletal syndrome overlap with those of a similar condition called Crouzon syndrome. Common features include premature fusion of the skull bones, which affects the shape of the head and face; wide-set, bulging eyes due to shallow eye sockets; eyes that do not point in the same direction (strabismus); a small, beaked nose; and an underdeveloped upper jaw. People with Crouzon syndrome or Crouzonodermoskeletal syndrome usually have normal intelligence.  Several features distinguish Crouzonodermoskeletal syndrome from Crouzon syndrome. People with Crouzonodermoskeletal syndrome have acanthosis nigricans, a skin condition characterized by thick, dark, velvety skin in body folds and creases, including the neck and underarms. In addition, subtle changes may be seen in the bones of the spine (vertebrae) on x-rays. Noncancerous growths called cementomas may develop in the jaw during young adulthood.
