What is (are) familial acute myeloid leukemia with mutated CEBPA ? 

Familial acute myeloid leukemia with mutated CEBPA is one form of a cancer of the blood-forming tissue (bone marrow) called acute myeloid leukemia. In normal bone marrow, early blood cells called hematopoietic stem cells develop into several types of blood cells: white blood cells (leukocytes) that protect the body from infection, red blood cells (erythrocytes) that carry oxygen, and platelets (thrombocytes) that are involved in blood clotting. In acute myeloid leukemia, the bone marrow makes large numbers of abnormal, immature white blood cells called myeloid blasts. Instead of developing into normal white blood cells, the myeloid blasts develop into cancerous leukemia cells. The large number of abnormal cells in the bone marrow interferes with the production of functional white blood cells, red blood cells, and platelets.  People with familial acute myeloid leukemia with mutated CEBPA have a shortage of white blood cells (leukopenia), leading to increased susceptibility to infections. A low number of red blood cells (anemia) also occurs in this disorder, resulting in fatigue and weakness. Affected individuals also have a reduction in the amount of platelets (thrombocytopenia), which can result in easy bruising and abnormal bleeding. Other symptoms of familial acute myeloid leukemia with mutated CEBPA may include fever and weight loss.  While acute myeloid leukemia is generally a disease of older adults, familial acute myeloid leukemia with mutated CEBPA often begins earlier in life, and it has been reported to occur as early as age 4. Between 50 and 65 percent of affected individuals survive their disease, compared with 25 to 40 percent of those with other forms of acute myeloid leukemia. However, people with familial acute myeloid leukemia with mutated CEBPA have a higher risk of having a new primary occurrence of this disorder after successful treatment of the initial occurrence.
How many people are affected by familial acute myeloid leukemia with mutated CEBPA ? 

Acute myeloid leukemia occurs in approximately 3.5 in 100,000 individuals per year. Familial acute myeloid leukemia with mutated CEBPA is a very rare form of acute myeloid leukemia; only a few affected families have been identified.
What are the genetic changes related to familial acute myeloid leukemia with mutated CEBPA ? 

As its name suggests, familial acute myeloid leukemia with mutated CEBPA is caused by mutations in the CEBPA gene that are passed down within families. These inherited mutations are present throughout a person's life in virtually every cell in the body.  The CEBPA gene provides instructions for making a protein called CCAAT/enhancer-binding protein alpha. This protein is a transcription factor, which means that it attaches (binds) to specific regions of DNA and helps control the activity of certain genes. It is believed to act as a tumor suppressor, helping to prevent cells from growing and dividing too rapidly or in an uncontrolled way.  CEBPA gene mutations that cause familial acute myeloid leukemia with mutated CEBPA result in a shorter version of CCAAT/enhancer-binding protein alpha. This shorter version is produced from one copy of the CEBPA gene in each cell, and it is believed to interfere with the tumor suppressor function of the normal protein produced from the second copy of the gene. Absence of the tumor suppressor function of CCAAT/enhancer-binding protein alpha is believed to disrupt the regulation of blood cell production in the bone marrow, leading to the uncontrolled production of abnormal cells that occurs in acute myeloid leukemia.  In addition to the inherited mutation in one copy of the CEBPA gene in each cell, most individuals with familial acute myeloid leukemia with mutated CEBPA also acquire a mutation in the second copy of the CEBPA gene. The additional mutation, which is called a somatic mutation, is found only in the leukemia cells and is not inherited. The somatic CEBPA gene mutations identified in leukemia cells generally decrease the DNA-binding ability of CCAAT/enhancer-binding protein alpha. The effect of this second mutation on the development of acute myeloid leukemia is unclear.
Is familial acute myeloid leukemia with mutated CEBPA inherited ? 

Familial acute myeloid leukemia with mutated CEBPA is inherited in an autosomal dominant pattern. Autosomal dominant inheritance means that one copy of the altered CEBPA gene in each cell is sufficient to cause the disorder. Most affected individuals also acquire a second, somatic CEBPA gene mutation in their leukemia cells.

What is (are) Carney complex ? 

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.
How many people are affected by Carney complex ? 

Carney complex is a rare disorder; fewer than 750 affected individuals have been identified.
What are the genetic changes related to Carney complex ? 

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.
Is Carney complex inherited ? 

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.

What is (are) Peutz-Jeghers syndrome ? 

Peutz-Jeghers syndrome is characterized by the development of noncancerous growths called hamartomatous polyps in the gastrointestinal tract (particularly the stomach and intestines) and a greatly increased risk of developing certain types of cancer.  Children with Peutz-Jeghers syndrome often develop small, dark-colored spots on the lips, around and inside the mouth, near the eyes and nostrils, and around the anus. These spots may also occur on the hands and feet. They appear during childhood and often fade as the person gets older. In addition, most people with Peutz-Jeghers syndrome develop multiple polyps in the stomach and intestines during childhood or adolescence. Polyps can cause health problems such as recurrent bowel obstructions, chronic bleeding, and abdominal pain.  People with Peutz-Jeghers syndrome have a high risk of developing cancer during their lifetimes. Cancers of the gastrointestinal tract, pancreas, cervix, ovary, and breast are among the most commonly reported tumors.
How many people are affected by Peutz-Jeghers syndrome ? 

The prevalence of this condition is uncertain; estimates range from 1 in 25,000 to 300,000 individuals.
What are the genetic changes related to Peutz-Jeghers syndrome ? 

Mutations in the STK11 gene (also known as LKB1) cause most cases of Peutz-Jeghers syndrome. The STK11 gene is a tumor suppressor gene, which means that it normally prevents cells from growing and dividing too rapidly or in an uncontrolled way. A mutation in this gene alters the structure or function of the STK11 protein, disrupting its ability to restrain cell division. The resulting uncontrolled cell growth leads to the formation of noncancerous polyps and cancerous tumors in people with Peutz-Jeghers syndrome.  A small percentage of people with Peutz-Jeghers syndrome do not have mutations in the STK11 gene. In these cases, the cause of the disorder is unknown.
Is Peutz-Jeghers syndrome inherited ? 

Peutz-Jeghers syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to increase the risk of developing noncancerous polyps and cancerous tumors. In about half of all cases, an affected person inherits a mutation in the STK11 gene from one affected parent. The remaining cases occur in people with no history of Peutz-Jeghers syndrome in their family. These cases appear to result from new (de novo) mutations in the STK11 gene.

What is (are) congenital sucrase-isomaltase deficiency ? 

Congenital sucrase-isomaltase deficiency is a disorder that affects a person's ability to digest certain sugars. People with this condition cannot break down the sugars sucrose and maltose. Sucrose (a sugar found in fruits, and also known as table sugar) and maltose (the sugar found in grains) are called disaccharides because they are made of two simple sugars. Disaccharides are broken down into simple sugars during digestion. Sucrose is broken down into glucose and another simple sugar called fructose, and maltose is broken down into two glucose molecules. People with congenital sucrase-isomaltase deficiency cannot break down the sugars sucrose and maltose, and other compounds made from these sugar molecules (carbohydrates).  Congenital sucrase-isomaltase deficiency usually becomes apparent after an infant is weaned and starts to consume fruits, juices, and grains. After ingestion of sucrose or maltose, an affected child will typically experience stomach cramps, bloating, excess gas production, and diarrhea. These digestive problems can lead to failure to gain weight and grow at the expected rate (failure to thrive) and malnutrition. Most affected children are better able to tolerate sucrose and maltose as they get older.
How many people are affected by congenital sucrase-isomaltase deficiency ? 

The prevalence of congenital sucrase-isomaltase deficiency is estimated to be 1 in 5,000 people of European descent. This condition is much more prevalent in the native populations of Greenland, Alaska, and Canada, where as many as 1 in 20 people may be affected.
What are the genetic changes related to congenital sucrase-isomaltase deficiency ? 

Mutations in the SI gene cause congenital sucrase-isomaltase deficiency. The SI gene provides instructions for producing the enzyme sucrase-isomaltase. This enzyme is found in the small intestine and is responsible for breaking down sucrose and maltose into their simple sugar components. These simple sugars are then absorbed by the small intestine. Mutations that cause this condition alter the structure, disrupt the production, or impair the function of sucrase-isomaltase. These changes prevent the enzyme from breaking down sucrose and maltose, causing the intestinal discomfort seen in individuals with congenital sucrase-isomaltase deficiency.
Is congenital sucrase-isomaltase deficiency 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) epidermal nevus ? 

An epidermal nevus (plural: nevi) is an abnormal, noncancerous (benign) patch of skin caused by an overgrowth of skin cells. Epidermal nevi are typically seen at birth or develop in early childhood. They can be flat, tan patches of skin or raised, velvety patches. As the affected individual ages, the nevus can become thicker and darker and develop a wart-like (verrucous) appearance. Often, epidermal nevi follow a pattern on the skin known as the lines of Blaschko. The lines of Blaschko, which are invisible on skin, are thought to follow the paths along which cells migrate as the skin develops before birth.  There are several types of epidermal nevi that are defined in part by the type of skin cell involved. The epidermis is the outermost layer of skin and is composed primarily of a specific cell type called a keratinocyte. One group of epidermal nevi, called keratinocytic or nonorganoid epidermal nevi, includes nevi that involve only keratinocytes. Other types of epidermal nevi involve additional types of epidermal cells, such as the cells that make up the hair follicles or the sebaceous glands (glands in the skin that produce a substance that protects the skin and hair). These nevi comprise a group called organoid epidermal nevi.  Some affected individuals have only an epidermal nevus and no other abnormalities. However, sometimes people with an epidermal nevus also have problems in other body systems, such as the brain, eyes, or bones. In these cases, the affected individual has a condition called an epidermal nevus syndrome. There are several different epidermal nevus syndromes characterized by the type of epidermal nevus involved.
How many people are affected by epidermal nevus ? 

Epidermal nevi affect approximately 1 in 1,000 people.
What are the genetic changes related to epidermal nevus ? 

Mutations in the FGFR3 gene have been found in approximately 30 percent of people with a type of nevus in the keratinocytic epidermal nevi group. The gene mutations involved in most epidermal nevi are unknown.  Mutations associated with an epidermal nevus are present only in the cells of the nevus, not in the normal skin cells surrounding it. Because the mutation is found in some of the body's cells but not in others, people with an epidermal nevus are said to be mosaic for the mutation.  The FGFR3 gene provides instructions for the fibroblast growth factor receptor 3 (FGFR3) protein. This protein is involved in several important cellular processes, including regulation of growth and division of skin cells. The FGFR3 protein interacts with specific growth factors outside the cell to receive signals that control growth and development. When these growth factors attach to the FGFR3 protein, the protein is turned on (activated), which triggers a cascade of chemical reactions inside the cell that control growth and other cellular functions.  The most common FGFR3 gene mutation in epidermal nevi creates a protein that is turned on without attachment of a growth factor, which means that the FGFR3 protein is constantly active. Cells with a mutated FGFR3 gene grow and divide more than normal cells. In addition, these mutated cells do not undergo a form of self-destruction called apoptosis as readily as normal cells. These effects result in overgrowth of skin cells, leading to epidermal nevi.
Is epidermal nevus inherited ? 

This condition is generally not inherited but arises from mutations in the body's cells that occur after conception. This alteration is called a somatic mutation.  Occasionally, the somatic mutation occurs in a person's reproductive cells (sperm or eggs) and is passed to the next generation. An inherited FGFR3 gene mutation is found in every cell in the body, which results in skeletal abnormalities rather than epidermal nevus.

What is (are) trisomy 18 ? 

Trisomy 18, also called Edwards syndrome, is a chromosomal condition associated with abnormalities in many parts of the body. Individuals with trisomy 18 often have slow growth before birth (intrauterine growth retardation) and a low birth weight. Affected individuals may have heart defects and abnormalities of other organs that develop before birth. Other features of trisomy 18 include a small, abnormally shaped head; a small jaw and mouth; and clenched fists with overlapping fingers. Due to the presence of several life-threatening medical problems, many individuals with trisomy 18 die before birth or within their first month. Five to 10 percent of children with this condition live past their first year, and these children often have severe intellectual disability.
How many people are affected by trisomy 18 ? 

Trisomy 18 occurs in about 1 in 5,000 live-born infants; it is more common in pregnancy, but many affected fetuses do not survive to term. Although women of all ages can have a child with trisomy 18, the chance of having a child with this condition increases as a woman gets older.
What are the genetic changes related to trisomy 18 ? 

Most cases of trisomy 18 result from having three copies of chromosome 18 in each cell in the body instead of the usual two copies. The extra genetic material disrupts the normal course of development, causing the characteristic features of trisomy 18.  Approximately 5 percent of people with trisomy 18 have an extra copy of chromosome 18 in only some of the body's cells. In these people, the condition is called mosaic trisomy 18. The severity of mosaic trisomy 18 depends on the type and number of cells that have the extra chromosome. The development of individuals with this form of trisomy 18 may range from normal to severely affected.  Very rarely, part of the long (q) arm of chromosome 18 becomes attached (translocated) to another chromosome during the formation of reproductive cells (eggs and sperm) or very early in embryonic development. Affected individuals have two copies of chromosome 18, plus the extra material from chromosome 18 attached to another chromosome. People with this genetic change are said to have partial trisomy 18. If only part of the q arm is present in three copies, the physical signs of partial trisomy 18 may be less severe than those typically seen in trisomy 18. If the entire q arm is present in three copies, individuals may be as severely affected as if they had three full copies of chromosome 18.
