Question: What is (are) paroxysmal extreme pain disorder ?
Answer: Paroxysmal extreme pain disorder is a condition characterized by skin redness and warmth (flushing) and attacks of severe pain in various parts of the body. The area of flushing typically corresponds to the site of the pain. The pain attacks experienced by people with paroxysmal extreme pain disorder usually last seconds to minutes, but in some cases can last hours. These attacks can start as early as infancy. Early in life, the pain is typically concentrated in the lower part of the body, especially around the rectum, and is usually triggered by a bowel movement. Some children may develop constipation, which is thought to be due to fear of triggering a pain attack. Pain attacks in these young children may also be accompanied by seizures, slow heartbeat, or short pauses in breathing (apnea).  As a person with paroxysmal extreme pain disorder ages, the location of pain changes. Pain attacks switch from affecting the lower body to affecting the head and face, especially the eyes and jaw. Triggers of these pain attacks include changes in temperature (such as a cold wind) and emotional distress as well as eating spicy foods and drinking cold drinks.  Paroxysmal extreme pain disorder is considered a form of peripheral neuropathy because it affects the peripheral nervous system, which connects the brain and spinal cord to muscles and to cells that detect sensations such as touch, smell, and pain.

Question: What are the genetic changes related to paroxysmal extreme pain disorder ?
Answer: Mutations in the SCN9A gene cause paroxysmal extreme pain disorder. The SCN9A gene provides instructions for making one part (the alpha subunit) of a sodium channel called NaV1.7. Sodium channels transport positively charged sodium atoms (sodium ions) into cells and play a key role in a cell's ability to generate and transmit electrical signals. NaV1.7 sodium channels are found in nerve cells called nociceptors that transmit pain signals to the spinal cord and brain.  The SCN9A gene mutations that cause paroxysmal extreme pain disorder result in NaV1.7 sodium channels that do not close completely when it is turned off, allowing sodium ions to flow abnormally into nociceptors. This increase in sodium ions enhances transmission of pain signals, leading to the pain attacks experienced by people with paroxysmal extreme pain disorder. It is unknown why the pain attacks associated with this condition change location over time or what causes the other features of this condition such as seizures and changes in breathing.

Topic: Denys-Drash syndrome
Question: What is (are) Denys-Drash syndrome ?
Answer: Denys-Drash syndrome is a condition that affects the kidneys and genitalia.  Denys-Drash syndrome is characterized by kidney disease that begins within the first few months of life. Affected individuals have a condition called diffuse glomerulosclerosis, in which scar tissue forms throughout glomeruli, which are the tiny blood vessels in the kidneys that filter waste from blood. In people with Denys-Drash syndrome, this condition often leads to kidney failure in childhood. People with Denys-Drash syndrome have an estimated 90 percent chance of developing a rare form of kidney cancer known as Wilms tumor. Affected individuals may develop multiple tumors in one or both kidneys.  Although males with Denys-Drash syndrome have the typical male chromosome pattern (46,XY), they have gonadal dysgenesis, in which external genitalia do not look clearly male or clearly female (ambiguous genitalia) or the genitalia appear completely female. The testes of affected males are undescended, which means they are abnormally located in the pelvis, abdomen, or groin. As a result, males with Denys-Drash are typically unable to have biological children (infertile).  Affected females usually have normal genitalia and have only the kidney features of the condition. Because they do not have all the features of the condition, females are usually given the diagnosis of isolated nephrotic syndrome.

Topic: Denys-Drash syndrome
Question: What are the genetic changes related to Denys-Drash syndrome ?
Answer: Mutations in the WT1 gene cause Denys-Drash syndrome. The WT1 gene provides instructions for making a protein that regulates the activity of other genes by attaching (binding) to specific regions of DNA. On the basis of this action, the WT1 protein is called a transcription factor. The WT1 protein plays a role in the development of the kidneys and kidneys and gonads (ovaries in females and testes in males) before birth.  WT1 gene mutations that cause Denys-Drash syndrome lead to the production of an abnormal protein that cannot bind to DNA. As a result, the activity of certain genes is unregulated, which impairs the development of the kidneys and reproductive organs. Abnormal development of these organs leads to diffuse glomerulosclerosis and gonadal dysgenesis, which are characteristic of Denys-Drash syndrome. Abnormal gene activity caused by the loss of normal WT1 protein increases the risk of developing Wilms tumor in affected individuals.  Denys-Drash syndrome has features similar to another condition called Frasier syndrome, which is also caused by mutations in the WT1 gene. Because these two conditions share a genetic cause and have overlapping features, some researchers have suggested that they are part of a spectrum and not two distinct conditions.

Topic: X-linked lissencephaly with abnormal genitalia
Question: What is (are) X-linked lissencephaly with abnormal genitalia ?
Answer: X-linked lissencephaly with abnormal genitalia (XLAG) is a condition that affects the development of the brain and genitalia. It occurs most often in males.  XLAG is characterized by abnormal brain development that results in the brain having a smooth appearance (lissencephaly) instead of its normal folds and grooves. Individuals without any folds in the brain (agyria) typically have more severe symptoms than people with reduced folds and grooves (pachygyria). Individuals with XLAG may also have a lack of development (agenesis) of the tissue connecting the left and right halves of the brain (corpus callosum). The brain abnormalities can cause severe intellectual disability and developmental delay, abnormal muscle stiffness (spasticity), weak muscle tone (hypotonia), and feeding difficulties. Starting soon after birth, babies with XLAG have frequent and recurrent seizures (epilepsy). Most children with XLAG do not survive past early childhood.  Another key feature of XLAG in males is abnormal genitalia that can include an unusually small penis (micropenis), undescended testes (cryptorchidism), or external genitalia that do not look clearly male or clearly female (ambiguous genitalia).  Additional signs and symptoms of XLAG include chronic diarrhea, periods of increased blood sugar (transient hyperglycemia), and problems with body temperature regulation.

Topic: X-linked lissencephaly with abnormal genitalia
Question: What are the genetic changes related to X-linked lissencephaly with abnormal genitalia ?
Answer: Mutations in the ARX gene cause XLAG. The ARX gene provides instructions for producing a protein that is involved in the development of several organs, including the brain, testes, and pancreas. In the developing brain, the ARX protein is involved with movement and communication in nerve cells (neurons). The ARX protein regulates genes that play a role in the migration of specialized neurons (interneurons) to their proper location. Interneurons relay signals between neurons. In the pancreas and testes, the ARX protein helps to regulate the process by which cells mature to carry out specific functions (differentiation).  ARX gene mutations lead to the production of a nonfunctional ARX protein or to the complete absence of ARX protein. As a result, the ARX protein cannot perform its role regulating the activity of genes important for interneuron migration. In addition to impairing normal brain development, a lack of functional ARX protein disrupts cell differentiation during the formation of the testes, leading to abnormal genitalia. It is thought that the disruption of ARX protein function in the pancreas plays a role in the chronic diarrhea and hyperglycemia experienced by individuals with XLAG.

Topic: X-linked lissencephaly with abnormal genitalia
Question: Is X-linked lissencephaly with abnormal genitalia inherited ?
Answer: This condition is inherited in an X-linked pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes in each cell. 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 copies of the X chromosome, one altered copy of the gene in each cell can lead to less severe brain malformations or may cause no symptoms at all. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

Topic: neonatal onset multisystem inflammatory disease
Question: What is (are) neonatal onset multisystem inflammatory disease ?
Answer: Neonatal onset multisystem inflammatory disease (NOMID) is a disorder that causes persistent inflammation and tissue damage primarily affecting the nervous system, skin, and joints. Recurrent episodes of mild fever may also occur in this disorder.  People with NOMID have a skin rash that is usually present from birth. The rash persists throughout life, although it changes in size and location.  Affected individuals often have headaches, seizures, and vomiting resulting from chronic meningitis, which is inflammation of the tissue that covers and protects the brain and spinal cord (meninges). Intellectual disability may occur in some people with this disorder. Hearing and vision problems may result from nerve damage and inflammation in various tissues of the eyes.  People with NOMID experience joint inflammation, swelling, and cartilage overgrowth, causing characteristic prominent knees and other skeletal abnormalities that worsen over time. Joint deformities called contractures may restrict the movement of certain joints.  Other features of this disorder include short stature with shortening of the lower legs and forearms, and characteristic facial features such as a prominent forehead and protruding eyes. Abnormal deposits of a protein called amyloid (amyloidosis) may cause progressive kidney damage.

Topic: neonatal onset multisystem inflammatory disease
Question: What are the genetic changes related to neonatal onset multisystem inflammatory disease ?
Answer: Mutations in the NLRP3 gene (also known as CIAS1) cause NOMID. The NLRP3 gene provides instructions for making a protein called cryopyrin.  Cryopyrin belongs to a family of proteins called nucleotide-binding domain and leucine-rich repeat containing (NLR) proteins. These proteins are involved in the immune system, helping to regulate the process of inflammation. Inflammation occurs when the immune system sends signaling molecules and white blood cells to a site of injury or disease to fight microbial invaders and facilitate tissue repair. When this has been accomplished, the body stops (inhibits) the inflammatory response to prevent damage to its own cells and tissues.  Cryopyrin is involved in the assembly of a molecular complex called an inflammasome, which helps trigger the inflammatory process. Researchers believe that NLRP3 mutations that cause NOMID result in a hyperactive cryopyrin protein and an inappropriate inflammatory response. Impairment of the body's mechanisms for controlling inflammation results in the episodes of fever and widespread inflammatory damage to the body's cells and tissues seen in NOMID.  In about 50 percent of individuals diagnosed with NOMID, no mutations in the NLRP3 gene have been identified. The cause of NOMID in these individuals is unknown.

Question: Is neonatal onset multisystem inflammatory disease inherited ?
Answer: 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 almost all cases, NOMID results from new mutations. These cases occur in people with no history of the disorder in their family. A few cases have been reported in which an affected person has inherited the mutation from one affected parent.

Topic: aceruloplasminemia
Question: What is (are) aceruloplasminemia ?
Answer: Aceruloplasminemia is a disorder in which iron gradually accumulates in the brain and other organs. Iron accumulation in the brain results in neurological problems that generally appear in adulthood and worsen over time.  People with aceruloplasminemia develop a variety of movement problems. They may experience involuntary muscle contractions (dystonia) of the head and neck, resulting in repetitive movements and contortions. Other involuntary movements may also occur, such as rhythmic shaking (tremors), jerking movements (chorea), eyelid twitching (blepharospasm), and grimacing. Affected individuals may also have difficulty with coordination (ataxia). Some develop psychiatric problems and a decline of intellectual function (dementia) in their forties or fifties.  In addition to neurological problems, affected individuals may have diabetes mellitus caused by iron damage to cells in the pancreas that make insulin, a hormone that helps control blood sugar levels. Iron accumulation in the pancreas reduces the cells' ability to make insulin, which impairs blood sugar regulation and leads to the signs and symptoms of diabetes.  Iron accumulation in the tissues and organs results in a corresponding shortage (deficiency) of iron in the blood, leading to a shortage of red blood cells (anemia). Anemia and diabetes usually occur by the time an affected person is in his or her twenties.  Affected individuals also have changes in the light-sensitive tissue at the back of the eye (retina) caused by excess iron. The changes result in small opaque spots and areas of tissue degeneration (atrophy) around the edges of the retina. These abnormalities usually do not affect vision but can be observed during an eye examination.  The specific features of aceruloplasminemia and their severity may vary, even within the same family.

Topic: aceruloplasminemia
Question: What are the genetic changes related to aceruloplasminemia ?
Answer: Mutations in the CP gene cause aceruloplasminemia. The CP gene provides instructions for making a protein called ceruloplasmin, which is involved in iron transport and processing. Ceruloplasmin helps move iron from the organs and tissues of the body and prepares it for incorporation into a molecule called transferrin, which transports it to red blood cells to help carry oxygen.  CP gene mutations result in the production of ceruloplasmin protein that is unstable or nonfunctional, or they prevent the protein from being released (secreted) by the cells in which it is made. When ceruloplasmin is unavailable, transport of iron out of the body's tissues is impaired. The resulting iron accumulation damages cells in those tissues, leading to neurological dysfunction, and the other health problems seen in aceruloplasminemia.

Topic: color vision deficiency
Question: What is (are) color vision deficiency ?
Answer: Color vision deficiency (sometimes called color blindness) represents a group of conditions that affect the perception of color. Red-green color vision defects are the most common form of color vision deficiency. Affected individuals have trouble distinguishing between some shades of red, yellow, and green. Blue-yellow color vision defects (also called tritan defects), which are rarer, cause problems with differentiating shades of blue and green and cause difficulty distinguishing dark blue from black. These two forms of color vision deficiency disrupt color perception but do not affect the sharpness of vision (visual acuity).  A less common and more severe form of color vision deficiency called blue cone monochromacy causes very poor visual acuity and severely reduced color vision. Affected individuals have additional vision problems, which can include increased sensitivity to light (photophobia), involuntary back-and-forth eye movements (nystagmus), and nearsightedness (myopia). Blue cone monochromacy is sometimes considered to be a form of achromatopsia, a disorder characterized by a partial or total lack of color vision with other vision problems.

Question: How many people are affected by color vision deficiency ?
Answer: Red-green color vision defects are the most common form of color vision deficiency. This condition affects males much more often than females. Among populations with Northern European ancestry, it occurs in about 1 in 12 males and 1 in 200 females. Red-green color vision defects have a lower incidence in almost all other populations studied.  Blue-yellow color vision defects affect males and females equally. This condition occurs in fewer than 1 in 10,000 people worldwide.  Blue cone monochromacy is rarer than the other forms of color vision deficiency, affecting about 1 in 100,000 people worldwide. Like red-green color vision defects, blue cone monochromacy affects males much more often than females.

Topic: color vision deficiency
Question: Is color vision deficiency inherited ?
Answer: Red-green color vision defects and blue cone monochromacy are inherited in an X-linked recessive pattern. The OPN1LW and OPN1MW genes are located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one genetic change in each cell is sufficient to cause the condition. Males are affected by X-linked recessive disorders much more frequently than females because in females (who have two X chromosomes), a genetic change would have to occur on both copies of the chromosome to cause the disorder. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.  Blue-yellow color vision defects are inherited in an autosomal dominant pattern, which means one copy of the altered OPN1SW gene in each cell is sufficient to cause the condition. In many cases, an affected person inherits the condition from an affected parent.
