 What is (are) Duchenne and Becker muscular dystrophy ? 
 Muscular dystrophies are a group of genetic conditions characterized by progressive muscle weakness and wasting (atrophy). The Duchenne and Becker types of muscular dystrophy are two related conditions that primarily affect skeletal muscles, which are used for movement, and heart (cardiac) muscle. These forms of muscular dystrophy occur almost exclusively in males.  Duchenne and Becker muscular dystrophies have similar signs and symptoms and are caused by different mutations in the same gene. The two conditions differ in their severity, age of onset, and rate of progression. In boys with Duchenne muscular dystrophy, muscle weakness tends to appear in early childhood and worsen rapidly. Affected children may have delayed motor skills, such as sitting, standing, and walking. They are usually wheelchair-dependent by adolescence. The signs and symptoms of Becker muscular dystrophy are usually milder and more varied. In most cases, muscle weakness becomes apparent later in childhood or in adolescence and worsens at a much slower rate.  Both the Duchenne and Becker forms of muscular dystrophy are associated with a heart condition called cardiomyopathy. This form of heart disease weakens the cardiac muscle, preventing the heart from pumping blood efficiently. In both Duchenne and Becker muscular dystrophy, cardiomyopathy typically begins in adolescence. Later, the heart muscle becomes enlarged, and the heart problems develop into a condition known as dilated cardiomyopathy. Signs and symptoms of dilated cardiomyopathy can include an irregular heartbeat (arrhythmia), shortness of breath, extreme tiredness (fatigue), and swelling of the legs and feet. These heart problems worsen rapidly and become life-threatening in many cases. Males with Duchenne muscular dystrophy typically live into their twenties, while males with Becker muscular dystrophy can survive into their forties or beyond.  A related condition called DMD-associated dilated cardiomyopathy is a form of heart disease caused by mutations in the same gene as Duchenne and Becker muscular dystrophy, and it is sometimes classified as subclinical Becker muscular dystrophy. People with DMD-associated dilated cardiomyopathy typically do not have any skeletal muscle weakness or wasting, although they may have subtle changes in their skeletal muscle cells that are detectable through laboratory testing.

 How many people are affected by Duchenne and Becker muscular dystrophy ? 
 Duchenne and Becker muscular dystrophies together affect 1 in 3,500 to 5,000 newborn males worldwide. Between 400 and 600 boys in the United States are born with these conditions each year.
This is a medical question of type : genetic changes 
 What are the genetic changes related to Duchenne and Becker muscular dystrophy ? 
 Mutations in the DMD gene cause the Duchenne and Becker forms of muscular dystrophy. The DMD gene provides instructions for making a protein called dystrophin. This protein is located primarily in skeletal and cardiac muscle, where it helps stabilize and protect muscle fibers. Dystrophin may also play a role in chemical signaling within cells.  Mutations in the DMD gene alter the structure or function of dystrophin or prevent any functional dystrophin from being produced. Muscle cells without enough of this protein become damaged as muscles repeatedly contract and relax with use. The damaged fibers weaken and die over time, leading to the muscle weakness and heart problems characteristic of Duchenne and Becker muscular dystrophies. Mutations that lead to an abnormal version of dystrophin that retains some function usually cause Becker muscular dystrophy, while mutations that prevent the production of any functional dystrophin tend to cause Duchenne muscular dystrophy.  Because Duchenne and Becker muscular dystrophies result from faulty or missing dystrophin, these conditions are classified as dystrophinopathies.
This is a medical question of type : inheritance 
 Is Duchenne and Becker muscular dystrophy inherited ? 
 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.  In about two-thirds of cases, an affected male inherits the mutation from his mother, who carries one altered copy of the DMD gene. The other one-third of cases probably result from new mutations in the gene in affected males and are not inherited.  In X-linked recessive inheritance, a female with one mutated copy of the gene in each cell is called a carrier. She can pass on the altered gene but usually does not experience signs and symptoms of the disorder. Occasionally, however, females who carry a DMD gene mutation may have muscle weakness and cramping. These symptoms are typically milder than the severe muscle weakness and atrophy seen in affected males. Females who carry a DMD gene mutation also have an increased risk of developing heart abnormalities including cardiomyopathy.

 What is (are) combined pituitary hormone deficiency ? 
 Combined pituitary hormone deficiency is a condition that causes a shortage (deficiency) of several hormones produced by the pituitary gland, which is located at the base of the brain. A lack of these hormones may affect the development of many parts of the body. The first signs of this condition include a failure to grow at the expected rate and short stature that usually becomes apparent in early childhood.  People with combined pituitary hormone deficiency may have hypothyroidism, which is underactivity of the butterfly-shaped thyroid gland in the lower neck. Hypothyroidism can cause many symptoms, including weight gain and fatigue. Other features of combined pituitary hormone deficiency include delayed or absent puberty and lack the ability to have biological children (infertility). The condition can also be associated with a deficiency of the hormone cortisol. Cortisol deficiency can impair the body's immune system, causing individuals to be more susceptible to infection.  Rarely, people with combined pituitary hormone deficiency have intellectual disability; a short, stiff neck; or underdeveloped optic nerves, which carry visual information from the eyes to the brain.

 How many people are affected by combined pituitary hormone deficiency ? 
 The prevalence of combined pituitary hormone deficiency is estimated to be 1 in 8,000 individuals worldwide.
This is a medical question of type : genetic changes 
 What are the genetic changes related to combined pituitary hormone deficiency ? 
 Mutations in at least eight genes have been found to cause combined pituitary hormone deficiency. Mutations in the PROP1 gene are the most common known cause of this disorder, accounting for an estimated 12 to 55 percent of cases. Mutations in other genes have each been identified in a smaller number of affected individuals.  The genes associated with combined pituitary hormone deficiency provide instructions for making proteins called transcription factors, which help control the activity of many other genes. The proteins are involved in the development of the pituitary gland and the specialization (differentiation) of its cell types. The cells of the pituitary gland are responsible for triggering the release of several hormones that direct the development of many parts of the body. Some of the transcription factors are found only in the pituitary gland, and some are also active in other parts of the body.  Mutations in the genes associated with combined pituitary hormone deficiency can result in abnormal differentiation of pituitary gland cells and may prevent the production of several hormones. These hormones can include growth hormone (GH), which is needed for normal growth; follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which both play a role in sexual development and the ability to have children (fertility); thyroid-stimulating hormone (TSH), which helps with thyroid gland function; prolactin, which stimulates the production of breast milk; and adrenocorticotropic hormone (ACTH), which influences energy production in the body and maintains normal blood sugar and blood pressure levels. The degree to which these hormones are deficient is variable, with prolactin and ACTH showing the most variability. In many affected individuals, ACTH deficiency does not occur until late adulthood.  Most people with combined pituitary hormone deficiency do not have identified mutations in any of the genes known to be associated with this condition. The cause of the disorder in these individuals is unknown.
This is a medical question of type : inheritance 
 Is combined pituitary hormone deficiency inherited ? 
 Most cases of combined pituitary hormone deficiency are sporadic, which means they occur in people with no history of the disorder in their family. Less commonly, this condition has been found to run in families. When the disorder is familial, it can have an autosomal dominant or an autosomal recessive pattern of inheritance.  Autosomal dominant inheritance means one copy of an altered gene in each cell is sufficient to cause the disorder.  Autosomal recessive inheritance 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 a mutated gene, but they typically do not show signs and symptoms of the condition. Most cases of familial combined pituitary hormone deficiency are inherited in an autosomal recessive pattern.

 What is (are) multiple mitochondrial dysfunctions syndrome ? 
 Multiple mitochondrial dysfunctions syndrome is characterized by impairment of cellular structures called mitochondria, which are the energy-producing centers of cells. While certain mitochondrial disorders are caused by impairment of a single stage of energy production, individuals with multiple mitochondrial dysfunctions syndrome have reduced function of more than one stage. The signs and symptoms of this severe condition begin early in life, and affected individuals usually do not live past infancy.  Affected infants typically have severe brain dysfunction (encephalopathy), which can contribute to weak muscle tone (hypotonia), seizures, and delayed development of mental and movement abilities (psychomotor delay). These infants often have difficulty growing and gaining weight at the expected rate (failure to thrive). Most affected babies have a buildup of a chemical called lactic acid in the body (lactic acidosis), which can be life-threatening. They may also have high levels of a molecule called glycine (hyperglycinemia) or elevated levels of sugar (hyperglycemia) in the blood. Some babies with multiple mitochondrial dysfunctions syndrome have high blood pressure in the blood vessels that connect to the lungs (pulmonary hypertension) or weakening of the heart muscle (cardiomyopathy).

 How many people are affected by multiple mitochondrial dysfunctions syndrome ? 
 Multiple mitochondrial dysfunctions syndrome is a rare condition; its prevalence is unknown. It is one of several conditions classified as mitochondrial disorders, which affect an estimated 1 in 5,000 people worldwide.
This is a medical question of type : genetic changes 
 What are the genetic changes related to multiple mitochondrial dysfunctions syndrome ? 
 Multiple mitochondrial dysfunctions syndrome can be caused by mutations in the NFU1 or BOLA3 gene. The proteins produced from each of these genes appear to be involved in the formation of molecules called iron-sulfur (Fe-S) clusters or in the attachment of these clusters to other proteins. Certain proteins require attachment of Fe-S clusters to function properly.  The NFU-1 and BOLA3 proteins play an important role in mitochondria. In these structures, several proteins carry out a series of chemical steps to convert the energy in food into a form that cells can use. Many of the proteins involved in these steps require Fe-S clusters to function, including protein complexes called complex I, complex II, and complex III.  Fe-S clusters are also required for another mitochondrial protein to function; this protein is involved in the modification of additional proteins that aid in energy production in mitochondria, including the pyruvate dehydrogenase complex and the alpha-ketoglutarate dehydrogenase complex (also known as the oxoglutarate dehydrogenase complex). This modification is also critical to the function of the glycine cleavage system, a set of proteins that breaks down a protein building block (amino acid) called glycine when levels become too high.  Mutations in the NFU1 or BOLA3 gene reduce or eliminate production of the respective protein, which impairs Fe-S cluster formation. Consequently, proteins affected by the presence of Fe-S clusters, including those involved in energy production and glycine breakdown, cannot function normally. Reduced activity of complex I, II, or III, pyruvate dehydrogenase, or alpha-ketoglutarate dehydrogenase leads to potentially fatal lactic acidosis, encephalopathy, and other signs and symptoms of multiple mitochondrial dysfunctions syndrome. In some affected individuals, impairment of the glycine cleavage system leads to a buildup of glycine.

 Is multiple mitochondrial dysfunctions syndrome inherited ? 
 This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations.

 How many people are affected by Charcot-Marie-Tooth disease ? 
 Charcot-Marie-Tooth disease is the most common inherited disorder that involves the peripheral nerves, affecting an estimated 150,000 people in the United States. It occurs in populations worldwide with a prevalence of about 1 in 2,500 individuals.
This is a medical question of type : genetic changes 
 What are the genetic changes related to Charcot-Marie-Tooth disease ? 
 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.
This is a medical question of type : inheritance 
 Is Charcot-Marie-Tooth disease inherited ? 
 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.

 What is (are) hypophosphatasia ? 
 Hypophosphatasia is an inherited disorder that affects the development of bones and teeth. This condition disrupts a process called mineralization, in which minerals such as calcium and phosphorus are deposited in developing bones and teeth. Mineralization is critical for the formation of bones that are strong and rigid and teeth that can withstand chewing and grinding.  The signs and symptoms of hypophosphatasia vary widely and can appear anywhere from before birth to adulthood. The most severe forms of the disorder tend to occur before birth and in early infancy. Hypophosphatasia weakens and softens the bones, causing skeletal abnormalities similar to another childhood bone disorder called rickets. Affected infants are born with short limbs, an abnormally shaped chest, and soft skull bones. Additional complications in infancy include poor feeding and a failure to gain weight, respiratory problems, and high levels of calcium in the blood (hypercalcemia), which can lead to recurrent vomiting and kidney problems. These complications are life-threatening in some cases.  The forms of hypophosphatasia that appear in childhood or adulthood are typically less severe than those that appear in infancy. Early loss of primary (baby) teeth is one of the first signs of the condition in children. Affected children may have short stature with bowed legs or knock knees, enlarged wrist and ankle joints, and an abnormal skull shape. Adult forms of hypophosphatasia are characterized by a softening of the bones known as osteomalacia. In adults, recurrent fractures in the foot and thigh bones can lead to chronic pain. Affected adults may lose their secondary (adult) teeth prematurely and are at increased risk for joint pain and inflammation.  The mildest form of this condition, called odontohypophosphatasia, only affects the teeth. People with this disorder typically experience abnormal tooth development and premature tooth loss, but do not have the skeletal abnormalities seen in other forms of hypophosphatasia.
This is a medical question of type : frequency 
 How many people are affected by hypophosphatasia ? 
 Severe forms of hypophosphatasia affect an estimated 1 in 100,000 newborns. Milder cases, such as those that appear in childhood or adulthood, probably occur more frequently.  Hypophosphatasia has been reported worldwide in people of various ethnic backgrounds. This condition appears to be most common in white populations. It is particularly frequent in a Mennonite population in Manitoba, Canada, where about 1 in 2,500 infants is born with severe features of the condition.
