Question:
How many people are affected by Gorlin syndrome ?

Answer:
Gorlin syndrome affects an estimated 1 in 31,000 people. While more than 1 million new cases of basal cell carcinoma are diagnosed each year in the United States, fewer than 1 percent of these skin cancers are related to Gorlin syndrome.
Question:
What are the genetic changes related to Gorlin syndrome ?

Answer:
Mutations in the PTCH1 gene cause Gorlin syndrome. This gene provides instructions for making a protein called patched-1, which functions as a receptor. Receptor proteins have specific sites into which certain other proteins, called ligands, fit like keys into locks. Together, ligands and their receptors trigger signals that affect cell development and function. A protein called Sonic Hedgehog is the ligand for the patched-1 receptor. Patched-1 blocks cell growth and division (proliferation) until Sonic Hedgehog is attached.  The PTCH1 gene is a tumor suppressor gene, which means it stops cells from proliferating too rapidly or in an uncontrolled way. Mutations in this gene prevent the production of patched-1 or lead to the production of an abnormal version of the receptor. An altered or missing patched-1 receptor cannot effectively suppress cell growth and division. As a result, cells proliferate uncontrollably to form the tumors that are characteristic of Gorlin syndrome. It is less clear how PTCH1 gene mutations cause the other signs and symptoms related to this condition.  The characteristic features of Gorlin syndrome can also be associated with a chromosomal change called a 9q22.3 microdeletion, in which a small piece of chromosome 9 is deleted in each cell. This deletion includes the segment of chromosome 9 that contains the PTCH1 gene, and as a result, people with a 9q22.3 microdeletion are missing one copy of this gene. Loss of this gene underlies the signs and symptoms of Gorlin syndrome in people with 9q22.3 microdeletions. Affected individuals also have features that are not typically associated with Gorlin syndrome, including delayed development, intellectual disability, overgrowth of the body (macrosomia), and other physical abnormalities. Researchers believe that these other signs and symptoms may result from the loss of additional genes in the deleted region of chromosome 9.
Question:
Is Gorlin syndrome inherited ?

Answer:
Gorlin syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the condition. In most cases, an affected person inherits the mutation from one affected parent. Other cases result from new mutations in the PTCH1 gene and occur in people with no history of the disorder in their family.  Having one mutated copy of the PTCH1 gene in each cell is enough to cause the features of Gorlin syndrome that are present early in life, including macrocephaly and skeletal abnormalities. For basal cell carcinomas and other tumors to develop, a mutation in the second copy of the PTCH1 gene must also occur in certain cells during the person's lifetime. Most people who are born with one PTCH1 gene mutation eventually acquire a second mutation in some cells and consequently develop various types of tumors.

Question:
What is (are) PDGFRA-associated chronic eosinophilic leukemia ?

Answer:
PDGFRA-associated chronic eosinophilic leukemia is a form of blood cell cancer characterized by an elevated number of cells called eosinophils in the blood. These cells help fight infections by certain parasites and are involved in the inflammation associated with allergic reactions. However, these circumstances do not account for the increased number of eosinophils in PDGFRA-associated chronic eosinophilic leukemia.  Another characteristic feature of PDGFRA-associated chronic eosinophilic leukemia is organ damage caused by the excess eosinophils. Eosinophils release substances to aid in the immune response, but the release of excessive amounts of these substances causes damage to one or more organs, most commonly the heart, skin, lungs, or nervous system. Eosinophil-associated organ damage can lead to a heart condition known as eosinophilic endomyocardial disease, skin rashes, coughing, difficulty breathing, swelling (edema) in the lower limbs, confusion, changes in behavior, or impaired movement or sensations. People with PDGFRA-associated chronic eosinophilic leukemia can also have an enlarged spleen (splenomegaly) and elevated levels of certain chemicals called vitamin B12 and tryptase in the blood.  Some people with PDGFRA-associated chronic eosinophilic leukemia have an increased number of other types of white blood cells, such as neutrophils or mast cells. Occasionally, people with PDGFRA-associated chronic eosinophilic leukemia develop other blood cell cancers, such as acute myeloid leukemia or B-cell or T-cell acute lymphoblastic leukemia or lymphoblastic lymphoma.  PDGFRA-associated chronic eosinophilic leukemia is often grouped with a related condition called hypereosinophilic syndrome. These two conditions have very similar signs and symptoms; however, the cause of hypereosinophilic syndrome is unknown.
Question:
How many people are affected by PDGFRA-associated chronic eosinophilic leukemia ?

Answer:
PDGFRA-associated chronic eosinophilic leukemia is a rare condition; however, the exact prevalence is unknown.
Question:
What are the genetic changes related to PDGFRA-associated chronic eosinophilic leukemia ?

Answer:
PDGFRA-associated chronic eosinophilic leukemia is caused by mutations in the PDGFRA gene. This condition usually occurs as a result of genetic rearrangements that fuse part of the PDGFRA gene with part of another gene. Rarely, changes in single DNA building blocks (point mutations) in the PDGFRA gene are found in people with this condition. Genetic rearrangements and point mutations affecting the PDGFRA gene are somatic mutations, which are mutations acquired during a person's lifetime that are present only in certain cells. The somatic mutation occurs initially in a single cell, which continues to grow and divide, producing a group of cells with the same mutation (a clonal population).  The most common genetic abnormality in PDGFRA-associated chronic eosinophilic leukemia results from a deletion of genetic material from chromosome 4, which brings together part of the PDGFRA gene and part of the FIP1L1 gene, creating the FIP1L1-PDGFRA fusion gene.  The FIP1L1 gene provides instructions for a protein that plays a role in forming the genetic blueprints for making proteins (messenger RNA or mRNA).  The PDGFRA gene provides instructions for making a receptor protein that is found in the cell membrane of certain cell types. Receptor proteins have specific sites into which certain other proteins, called ligands, fit like keys into locks. When the ligand attaches (binds), the PDGFRA receptor protein is turned on (activated), which leads to activation of a series of proteins in multiple signaling pathways. These signaling pathways control many important cellular processes, such as cell growth and division (proliferation) and cell survival.  The FIP1L1-PDGFRA fusion gene (as well as other PDGFRA fusion genes) provides instructions for making a fusion protein that has the function of the normal PDGFRA protein. However, the fusion protein does not require ligand binding to be activated. Similarly, point mutations in the PDGFRA gene can result in a PDGFRA protein that is activated without ligand binding. As a result, the signaling pathways are constantly turned on (constitutively activated), which increases the proliferation and survival of cells. When the FIP1L1-PDGFRA fusion gene mutation or point mutations in the PDGFRA gene occur in blood cell precursors, the growth of eosinophils (and occasionally other blood cells, such as neutrophils and mast cells) is poorly controlled, leading to PDGFRA-associated chronic eosinophilic leukemia. It is unclear why eosinophils are preferentially affected by this genetic change.
Question:
Is PDGFRA-associated chronic eosinophilic leukemia inherited ?

Answer:
PDGFRA-associated chronic eosinophilic leukemia is not inherited and occurs in people with no history of the condition in their families. Mutations that lead to a PDGFRA fusion gene and PDGFRA point mutations are somatic mutations, which means they occur during a person's lifetime and are found only in certain cells. Somatic mutations are not inherited. Males are more likely to develop PDGFRA-associated chronic eosinophilic leukemia than females because, for unknown reasons, PDGFRA fusion genes are found more often in males.

Question:
What is (are) mitochondrial complex III deficiency ?

Answer:
Mitochondrial complex III deficiency is a genetic condition that can affect several parts of the body, including the brain, kidneys, liver, heart, and the muscles used for movement (skeletal muscles). Signs and symptoms of mitochondrial complex III deficiency usually begin in infancy but can appear later.  The severity of mitochondrial complex III deficiency varies widely among affected individuals. People who are mildly affected tend to have muscle weakness (myopathy) and extreme tiredness (fatigue), particularly during exercise (exercise intolerance). More severely affected individuals have problems with multiple body systems, such as liver disease that can lead to liver failure, kidney abnormalities (tubulopathy), and brain dysfunction (encephalopathy). Encephalopathy can cause delayed development of mental and motor skills (psychomotor delay), movement problems, weak muscle tone (hypotonia), and difficulty with communication. Some affected individuals have a form of heart disease called cardiomyopathy, which can lead to heart failure. Most people with mitochondrial complex III deficiency have a buildup of a chemical called lactic acid in the body (lactic acidosis). Some affected individuals also have buildup of molecules called ketones (ketoacidosis) or high blood sugar levels (hyperglycemia). Abnormally high levels of these chemicals in the body can be life-threatening.  Mitochondrial complex III deficiency can be fatal in childhood, although individuals with mild signs and symptoms can survive into adolescence or adulthood.
Question:
How many people are affected by mitochondrial complex III deficiency ?

Answer:
The prevalence of mitochondrial complex III deficiency is unknown, although the condition is thought to be rare.
Question:
What are the genetic changes related to mitochondrial complex III deficiency ?

Answer:
Mitochondrial complex III deficiency can be caused by mutations in one of several genes. The proteins produced from these genes either are a part of or help assemble a group of proteins called complex III. The two most commonly mutated genes involved in mitochondrial complex III deficiency are MT-CYB and BCS1L. It is likely that genes that have not been identified are also involved in this condition.  Cytochrome b, produced from the MT-CYB gene, is one component of complex III, and the protein produced from the BCS1L gene is critical for the formation of the complex. Complex III is found in cell structures called mitochondria, which convert the energy from food into a form that cells can use. Complex III is one of several complexes that carry out a multistep process called oxidative phosphorylation, through which cells derive much of their energy. As a byproduct of its action in oxidative phosphorylation, complex III produces reactive oxygen species, which are harmful molecules that can damage DNA and tissues.  MT-CYB and BCS1L gene mutations impair the formation of complex III molecules. As a result, complex III activity and oxidative phosphorylation are reduced. Researchers believe that impaired oxidative phosphorylation can lead to cell death by reducing the amount of energy available in the cell. It is thought that tissues and organs that require a lot of energy, such as the brain, liver, kidneys, and skeletal muscles, are most affected by a reduction in oxidative phosphorylation. In addition, for unknown reasons, BCS1L gene mutations lead to increased overall production of reactive oxygen species, although production by complex III is reduced. Damage from reduced energy and from reactive oxygen species likely contributes to the signs and symptoms of mitochondrial complex III deficiency.  Unlike most genes, the MT-CYB gene is found in DNA located in mitochondria, called mitochondrial DNA (mtDNA). This location may help explain why some people have more severe features of the condition than others. Most of the body's cells contain thousands of mitochondria, each with one or more copies of mtDNA. These cells can have a mix of mitochondria containing mutated and unmutated DNA (heteroplasmy). When caused by MT-CYB gene mutations, the severity of mitochondrial complex III deficiency is thought to be associated with the percentage of mitochondria with the gene mutation. The other genes known to be involved in this condition are found in DNA packaged in chromosomes within the cell nucleus (nuclear DNA). It is not clear why the severity of the condition varies in people with mutations in these other genes.
Question:
Is mitochondrial complex III deficiency inherited ?

Answer:
Mitochondrial complex III deficiency is usually 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.  In some cases caused by mutations in the MT-CYB gene, the condition is not inherited; it is caused by new mutations in the gene that occur in people with no history of the condition in their family. Other cases caused by mutations in the MT-CYB gene are inherited in a mitochondrial pattern, which is also known as maternal inheritance. This pattern of inheritance applies to genes contained in mtDNA. Because egg cells, but not sperm cells, contribute mitochondria to the developing embryo, children can only inherit disorders resulting from mtDNA mutations from their mother. These disorders can appear in every generation of a family and can affect both males and females, but fathers do not pass traits associated with changes in mtDNA to their children.

Question:
What is (are) primary myelofibrosis ?

Answer:
Primary myelofibrosis is a condition characterized by the buildup of scar tissue (fibrosis) in the bone marrow, the tissue that produces blood cells. Because of the fibrosis, the bone marrow is unable to make enough normal blood cells. The shortage of blood cells causes many of the signs and symptoms of primary myelofibrosis.  Initially, most people with primary myelofibrosis have no signs or symptoms. Eventually, fibrosis can lead to a reduction in the number of red blood cells, white blood cells, and platelets. A shortage of red blood cells (anemia) often causes extreme tiredness (fatigue) or shortness of breath. A loss of white blood cells can lead to an increased number of infections, and a reduction of platelets can cause easy bleeding or bruising.  Because blood cell formation (hematopoiesis) in the bone marrow is disrupted, other organs such as the spleen or liver may begin to produce blood cells. This process, called extramedullary hematopoiesis, often leads to an enlarged spleen (splenomegaly) or an enlarged liver (hepatomegaly). People with splenomegaly may feel pain or fullness in the abdomen, especially below the ribs on the left side. Other common signs and symptoms of primary myelofibrosis include fever, night sweats, and bone pain.  Primary myelofibrosis is most commonly diagnosed in people aged 50 to 80 but can occur at any age.
Question:
How many people are affected by primary myelofibrosis ?

Answer:
Primary myelofibrosis is a rare condition that affects approximately 1 in 500,000 people worldwide.
Question:
What are the genetic changes related to primary myelofibrosis ?

Answer:
Mutations in the JAK2, MPL, CALR, and TET2 genes are associated with most cases of primary myelofibrosis. The JAK2 and MPL genes provide instructions for making proteins that promote the growth and division (proliferation) of blood cells. The CALR gene provides instructions for making a protein with multiple functions, including ensuring the proper folding of newly formed proteins and maintaining the correct levels of stored calcium in cells. The TET2 gene provides instructions for making a protein whose function is unknown.  The proteins produced from the JAK2 and MPL genes are both part of a signaling pathway called the JAK/STAT pathway, which transmits chemical signals from outside the cell to the cell's nucleus. The protein produced from the MPL gene, called thrombopoietin receptor, turns on (activates) the pathway, and the JAK2 protein transmits signals after activation. Through the JAK/STAT pathway, these two proteins promote the proliferation of blood cells, particularly a type of blood cell known as a megakaryocyte.  Mutations in either the JAK2 gene or the MPL gene that are associated with primary myelofibrosis lead to overactivation of the JAK/STAT pathway. The abnormal activation of JAK/STAT signaling leads to overproduction of abnormal megakaryocytes, and these megakaryocytes stimulate another type of cell to release collagen. Collagen is a protein that normally provides structural support for the cells in the bone marrow. However, in primary myelofibrosis, the excess collagen forms scar tissue in the bone marrow.  Although mutations in the CALR gene and the TET2 gene are relatively common in primary myelofibrosis, it is unclear how these mutations are involved in the development of the condition.  Some people with primary myelofibrosis do not have a mutation in any of the known genes associated with this condition. Researchers are working to identify other genes that may be involved in the condition.
Question:
Is primary myelofibrosis inherited ?

Answer:
This condition is generally not inherited but arises from gene mutations that occur in early blood-forming cells after conception. These alterations are called somatic mutations.

Question:
What is (are) Freeman-Sheldon syndrome ?

Answer:
Freeman-Sheldon syndrome is a condition that primarily affects the face, hands, and feet. People with this disorder have a distinctive facial appearance including a small mouth (microstomia) with pursed lips, giving the appearance of a "whistling face." For this reason, the condition is sometimes called "whistling face syndrome."  People with Freeman-Sheldon syndrome may also have a prominent forehead and brow ridges, a sunken appearance of the middle of the face (midface hypoplasia), a short nose, a long area between the nose and mouth (philtrum), deep folds in the skin between the nose and lips (nasolabial folds), full cheeks, and a chin dimple shaped like an "H" or "V".  Affected individuals may have a number of abnormalities that affect the eyes. These may include widely spaced eyes (hypertelorism), deep-set eyes, outside corners of the eyes that point downward (down-slanting palpebral fissures), a narrowing of the eye opening (blepharophimosis), droopy eyelids (ptosis), and eyes that do not look in the same direction (strabismus).  Other facial features that may occur in Freeman-Sheldon syndrome include an unusually small tongue (microglossia) and jaw (micrognathia) and a high arch in the roof of the mouth (high-arched palate). People with this disorder may have difficulty swallowing (dysphagia), a failure to gain weight and grow at the expected rate (failure to thrive), and respiratory complications that may be life-threatening. Speech problems are also common in this disorder. Some affected individuals have hearing loss.  Freeman-Sheldon syndrome is also characterized by joint deformities (contractures) that restrict movement. People with this disorder typically have multiple contractures in the hands and feet at birth (distal arthrogryposis). These contractures lead to permanently bent fingers and toes (camptodactyly), a hand deformity in which all of the fingers are angled outward toward the fifth finger (ulnar deviation, also called "windmill vane hand"), and inward- and downward-turning feet (clubfoot). Affected individuals may also have a spine that curves to the side (scoliosis).  People with Freeman-Sheldon syndrome also have an increased risk of developing a severe reaction to certain drugs used during surgery and other invasive procedures. This reaction is called malignant hyperthermia. Malignant hyperthermia occurs in response to some anesthetic gases, which are used to block the sensation of pain. A particular type of muscle relaxant may also trigger the reaction. If given these drugs, people at risk for malignant hyperthermia may experience muscle rigidity, breakdown of muscle fibers (rhabdomyolysis), a high fever, increased acid levels in the blood and other tissues (acidosis), and a rapid heart rate. The complications of malignant hyperthermia can be life-threatening unless they are treated promptly.  Intelligence is unaffected in most people with Freeman-Sheldon syndrome, but approximately one-third have some degree of intellectual disability.
Question:
How many people are affected by Freeman-Sheldon syndrome ?

Answer:
Freeman-Sheldon syndrome is a rare disorder; its exact prevalence is unknown.
