Question: What is (are) maple syrup urine disease ?
Answer: Maple syrup urine disease is an inherited disorder in which the body is unable to process certain protein building blocks (amino acids) properly. The condition gets its name from the distinctive sweet odor of affected infants' urine and is also characterized by poor feeding, vomiting, lack of energy (lethargy), and developmental delay. If untreated, maple syrup urine disease can lead to seizures, coma, and death. Maple syrup urine disease is often classified by its pattern of signs and symptoms. The most common and severe form of the disease is the classic type, which becomes apparent soon after birth. Variant forms of the disorder become apparent later in infancy or childhood and are typically milder, but they still involve developmental delay and other health problems if not treated.
Question: How many people are affected by maple syrup urine disease ?
Answer: Maple syrup urine disease affects an estimated 1 in 185,000 infants worldwide. The disorder occurs much more frequently in the Old Order Mennonite population, with an estimated incidence of about 1 in 380 newborns.
Question: What are the genetic changes related to maple syrup urine disease ?
Answer: Mutations in the BCKDHA, BCKDHB, and DBT genes can cause maple syrup urine disease. These three genes provide instructions for making proteins that work together as a complex. The protein complex is essential for breaking down the amino acids leucine, isoleucine, and valine, which are present in many kinds of food, particularly protein-rich foods such as milk, meat, and eggs. Mutations in any of these three genes reduce or eliminate the function of the protein complex, preventing the normal breakdown of leucine, isoleucine, and valine. As a result, these amino acids and their byproducts build up in the body. Because high levels of these substances are toxic to the brain and other organs, their accumulation leads to the serious health problems associated with maple syrup urine disease.
Question: Is maple syrup urine disease 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) chordoma ?
Answer: A chordoma is a rare type of cancerous tumor that can occur anywhere along the spine, from the base of the skull to the tailbone. Chordomas grow slowly, gradually extending into the bone and soft tissue around them. They often recur after treatment, and in about 40 percent of cases the cancer spreads (metastasizes) to other areas of the body, such as the lungs. Approximately half of all chordomas occur at the base of the spine (sacrum), about one third occur in the base of the skull (occiput), and the rest occur in the cervical (neck), thoracic (upper back), or lumbar (lower back) vertebrae of the spine. As the chordoma grows, it puts pressure on the adjacent areas of the brain or spinal cord, leading to the signs and symptoms of the disorder. A chordoma anywhere along the spine may cause pain, weakness, or numbness in the back, arms, or legs. A chordoma at the base of the skull (occipital chordoma) may lead to double vision (diplopia) and headaches. A chordoma that occurs in the tailbone (coccygeal chordoma) may result in a lump large enough to be felt through the skin and may cause problems with bladder or bowel function. Chordomas typically occur in adults between ages 40 and 70. About 5 percent of chordomas are diagnosed in children. For reasons that are unclear, males are affected about twice as often as females.
Question: How many people are affected by chordoma ?
Answer: Chordomas are rare, occurring in approximately 1 per million individuals each year. Chordomas comprise fewer than 1 percent of tumors affecting the brain and spinal cord.
Question: What are the genetic changes related to chordoma ?
Answer: Changes in the T gene have been associated with chordoma. An inherited duplication of the T gene identified in a few families is associated with an increased risk of developing a chordoma. Duplications or increases in activity (expression) of the T gene have also been identified in people with chordoma who have no history of the disorder in their family. In these individuals, the changes occur only in the tumor cells and are not inherited. The T gene provides instructions for making a protein called brachyury. Brachyury is a member of a protein family called T-box proteins, which play critical roles during embryonic development. T-box proteins regulate the activity of other genes by attaching (binding) to specific regions of DNA. On the basis of this action, T-box proteins are called transcription factors. The brachyury protein is especially important for the early development of the spine. In human embryos, a structure called the notochord is the precursor of the spinal column. The notochord disappears before birth, but in a small percentage of individuals, some of its cells remain in the base of the skull or in the spine. In rare cases these cells begin to grow and divide uncontrollably, invading the nearby bone and soft tissue and resulting in the development of a chordoma. Duplications and increases in expression of the T gene both result in the production of excess brachyury protein. The specific mechanism by which excess brachyury protein contributes to the development of chordomas is unclear. Some people with chordoma do not have changes in the T gene, and the cause of the disorder in these individuals is unknown.
Question: Is chordoma inherited ?
Answer: When development of a chordoma is associated with a duplication of the T gene inherited from a parent, one copy of the altered gene in each cell is sufficient to increase the risk of the disorder, which is an inheritance pattern called autosomal dominant. People with this duplication inherit an increased risk of this condition, not the condition itself. Other cases of chordoma are sporadic, which means they occur in people with no history of the condition in their family.

Question: What is (are) Carney complex ?
Answer: Carney complex is a disorder characterized by an increased risk of several types of tumors. Affected individuals also usually have changes in skin coloring (pigmentation). Signs and symptoms of this condition commonly begin in the teens or early adulthood. Individuals with Carney complex are at increased risk of developing noncancerous (benign) tumors called myxomas in the heart (cardiac myxoma) and other parts of the body. Cardiac myxomas may be found in any of the four chambers of the heart and can develop in more than one chamber. These tumors can block the flow of blood through the heart, causing serious complications or sudden death. Myxomas may also develop on the skin and in internal organs. Skin myxomas appear as small bumps on the surface of the skin or as lumps underneath the skin. In Carney complex, myxomas have a tendency to recur after they are removed. Individuals with Carney complex also develop tumors in hormone-producing (endocrine) glands, such as the adrenal glands located on top of each kidney. People with this condition may develop a specific type of adrenal disease called primary pigmented nodular adrenocortical disease (PPNAD). PPNAD causes the adrenal glands to produce an excess of the hormone cortisol. High levels of cortisol (hypercortisolism) can lead to the development of Cushing syndrome. This syndrome causes weight gain in the face and upper body, slowed growth in children, fragile skin, fatigue, and other health problems. People with Carney complex may also develop tumors of other endocrine tissues, including the thyroid, testes, and ovaries. A tumor called an adenoma may form in the pituitary gland, which is located at the base of the brain. A pituitary adenoma usually results in the production of too much growth hormone. Excess growth hormone leads to acromegaly, a condition characterized by large hands and feet, arthritis, and "coarse" facial features. Some people with Carney complex develop a rare tumor called psammomatous melanotic schwannoma. This tumor occurs in specialized cells called Schwann cells, which wrap around and insulate nerves. This tumor is usually benign, but in some cases it can become cancerous (malignant). Almost all people with Carney complex have areas of unusual skin pigmentation. Brown skin spots called lentigines may appear anywhere on the body but tend to occur around the lips, eyes, or genitalia. In addition, some affected individuals have at least one blue-black mole called a blue nevus.
Question: How many people are affected by Carney complex ?
Answer: Carney complex is a rare disorder; fewer than 750 affected individuals have been identified.
Question: What are the genetic changes related to Carney complex ?
Answer: Mutations in the PRKAR1A gene cause most cases of Carney complex. This gene provides instructions for making one part (subunit) of an enzyme called protein kinase A, which promotes cell growth and division (proliferation). The subunit produced from the PRKAR1A gene, called type 1 alpha, helps control whether protein kinase A is turned on or off. Most mutations in the PRKAR1A gene that cause Carney complex result in an abnormal type 1 alpha subunit that is quickly broken down (degraded) by the cell. The lack of this subunit causes protein kinase A to be turned on more often than normal, which leads to uncontrolled cell proliferation. The signs and symptoms of Carney complex are related to the unregulated growth of cells in many parts of the body. Some individuals with Carney complex do not have identified mutations in the PRKAR1A gene. In many of these cases, the disorder is associated with a specific region on the short (p) arm of chromosome 2, designated as 2p16. Researchers have not discovered the gene within this region that is responsible for Carney complex.
Question: Is Carney complex inherited ?
Answer: Carney complex 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 80 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 Carney complex in their family.

Question: What is (are) Smith-Lemli-Opitz syndrome ?
Answer: Smith-Lemli-Opitz syndrome is a developmental disorder that affects many parts of the body. This condition is characterized by distinctive facial features, small head size (microcephaly), intellectual disability or learning problems, and behavioral problems. Many affected children have the characteristic features of autism, a developmental condition that affects communication and social interaction. Malformations of the heart, lungs, kidneys, gastrointestinal tract, and genitalia are also common. Infants with Smith-Lemli-Opitz syndrome have weak muscle tone (hypotonia), experience feeding difficulties, and tend to grow more slowly than other infants. Most affected individuals have fused second and third toes (syndactyly), and some have extra fingers or toes (polydactyly). The signs and symptoms of Smith-Lemli-Opitz syndrome vary widely. Mildly affected individuals may have only minor physical abnormalities with learning and behavioral problems. Severe cases can be life-threatening and involve profound intellectual disability and major physical abnormalities.
Question: How many people are affected by Smith-Lemli-Opitz syndrome ?
Answer: Smith-Lemli-Opitz syndrome affects an estimated 1 in 20,000 to 60,000 newborns. This condition is most common in whites of European ancestry, particularly people from Central European countries such as Slovakia and the Czech Republic. It is very rare among African and Asian populations.
Question: What are the genetic changes related to Smith-Lemli-Opitz syndrome ?
Answer: Mutations in the DHCR7 gene cause Smith-Lemli-Opitz syndrome. The DHCR7 gene provides instructions for making an enzyme called 7-dehydrocholesterol reductase. This enzyme is responsible for the final step in the production of cholesterol. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals (particularly egg yolks, meat, poultry, fish, and dairy products). Cholesterol is necessary for normal embryonic development and has important functions both before and after birth. It is a structural component of cell membranes and the protective substance covering nerve cells (myelin). Additionally, cholesterol plays a role in the production of certain hormones and digestive acids. Mutations in the DHCR7 gene reduce or eliminate the activity of 7-dehydrocholesterol reductase, preventing cells from producing enough cholesterol. A lack of this enzyme also allows potentially toxic byproducts of cholesterol production to build up in the blood, nervous system, and other tissues. The combination of low cholesterol levels and an accumulation of other substances likely disrupts the growth and development of many body systems. It is not known, however, how this disturbance in cholesterol production leads to the specific features of Smith-Lemli-Opitz syndrome.
Question: Is Smith-Lemli-Opitz syndrome 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) Swyer syndrome ?
Answer: Swyer syndrome is a condition that affects sexual development. Sexual development is usually determined by an individual's chromosomes; however, in Swyer syndrome, sexual development does not match the affected individual's chromosomal makeup. People usually have 46 chromosomes in each cell. Two of the 46 chromosomes, known as X and Y, are called sex chromosomes because they help determine whether a person will develop male or female sex characteristics. Girls and women typically have two X chromosomes (46,XX karyotype), while boys and men usually have one X chromosome and one Y chromosome (46,XY karyotype). In Swyer syndrome, individuals with one X chromosome and one Y chromosome in each cell, the pattern typically found in boys and men, have female reproductive structures. People with Swyer syndrome have typical female external genitalia. The uterus and fallopian tubes are normally-formed, but the gonads (ovaries or testes) are not functional; affected individuals have undeveloped clumps of tissue called streak gonads. Because of the lack of development of the gonads, Swyer syndrome is also called 46,XY complete gonadal dysgenesis. The residual gonadal tissue often becomes cancerous, so it is usually removed surgically early in life. People with Swyer syndrome are typically raised as girls and have a female gender identity. Because they do not have functional ovaries, affected individuals usually begin hormone replacement therapy during adolescence to induce menstruation and development of female secondary sex characteristics such as breast enlargement and uterine growth. Hormone replacement therapy also helps reduce the risk of reduced bone density (osteopenia and osteoporosis). Women with this disorder do not produce eggs (ova), but they may be able to become pregnant with a donated egg or embryo. Swyer syndrome usually affects only sexual development; such cases are called isolated Swyer syndrome. However, depending on the genetic cause, Swyer syndrome may also occur along with health conditions such as nerve problems (neuropathy) or as part of a syndrome such as campomelic dysplasia, which causes severe skeletal abnormalities.
Question: How many people are affected by Swyer syndrome ?
Answer: Swyer syndrome occurs in approximately 1 in 80,000 people.
Question: What are the genetic changes related to Swyer syndrome ?
Answer: Mutations in the SRY gene have been identified in approximately 15 percent of individuals with Swyer syndrome. The SRY gene, located on the Y chromosome, provides instructions for making the sex-determining region Y protein. This protein is a transcription factor, which means it attaches (binds) to specific regions of DNA and helps control the activity of particular genes. The sex-determining region Y protein starts processes that are involved in male sexual development. These processes cause a fetus to develop male gonads (testes) and prevent the development of female reproductive structures (uterus and fallopian tubes). SRY gene mutations that cause Swyer syndrome prevent production of the sex-determining region Y protein or result in the production of a nonfunctioning protein. A fetus whose cells do not produce functional sex-determining region Y protein will not develop testes but will develop a uterus and fallopian tubes, despite having a typically male karyotype. Swyer syndrome can also be caused by mutations in the MAP3K1 gene; research indicates that mutations in this gene may account for up to 18 percent of cases. The MAP3K1 gene provides instructions for making a protein that helps regulate signaling pathways that control various processes in the body. These include the processes of determining sexual characteristics before birth. The mutations in this gene that cause Swyer syndrome decrease signaling that leads to male sexual differentiation and enhance signaling that leads to female sexual differentiation, preventing the development of testes and allowing the development of a uterus and fallopian tubes. Mutations in the DHH and NR5A1 genes have also been identified in small numbers of people with Swyer syndrome. The DHH gene provides instructions for making a protein that is important for early development of tissues in many parts of the body. The NR5A1 gene provides instructions for producing another transcription factor called the steroidogenic factor 1 (SF1). This protein helps control the activity of several genes related to the production of sex hormones and sexual differentiation. Mutations in the DHH and NR5A1 genes affect the process of sexual differentiation, preventing affected individuals with a typically male karyotype from developing testes and causing them to develop a uterus and fallopian tubes. Changes affecting other genes have also been identified in a small number of people with Swyer syndrome. Nongenetic factors, such as hormonal medications taken by the mother during pregnancy, have also been associated with this condition. However, in most individuals with Swyer syndrome, the cause is unknown.
Question: Is Swyer syndrome inherited ?
Answer: Most cases of Swyer syndrome are not inherited; they occur in people with no history of the condition in their family. These cases result either from nongenetic causes or from new (de novo) mutations in a gene that occur during the formation of reproductive cells (eggs or sperm) or in early embryonic development. SRY-related Swyer syndrome is usually caused by a new mutation. However, some individuals with Swyer syndrome inherit an altered SRY gene from an unaffected father who is mosaic for the mutation. Mosaic means that an individual has the mutation in some cells (including some reproductive cells) but not in others. In rare cases, a father may carry the mutation in every cell of the body but also has other genetic variations that prevent him from being affected by the condition. Because the SRY gene is on the Y chromosome, Swyer syndrome caused by SRY gene mutations is described as having a Y-linked inheritance pattern. When Swyer syndrome is associated with an MAP3K1 or NR5A1 gene mutation, the condition is also usually caused by a new mutation. In the rare inherited cases, the mutation may be inherited from either parent, since these genes are not on the Y chromosome. In these cases, the condition has an autosomal dominant pattern of inheritance, which means one copy of the altered gene in each cell is sufficient to cause the condition. Swyer syndrome caused by mutations in the DHH gene 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 are carriers of one copy of the altered gene. Female carriers of a DHH gene mutation generally have typical sex development. Male carriers of a DHH gene mutation may also be unaffected, or they may have genital differences such as the urethra opening on the underside of the penis (hypospadias).
