user: Is Larsen syndrome inherited ?

assistant: 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 some cases, an affected person inherits the mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the disorder in their family.  Autosomal recessive inheritance of Larsen syndrome has been reported in a small number of families. Autosomal recessive 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 of these cases, the appearance of autosomal recessive inheritance may actually result from multiple siblings in a family each inheriting a single altered gene from an unaffected parent who has an FLNB mutation only in some or all of their sperm or egg cells. When a mutation is present only in reproductive cells, it is known as germline mosaicism.  A few rarer conditions with overlapping signs and symptoms and autosomal recessive inheritance have sometimes been diagnosed as Larsen syndrome, but they are now generally considered to be different disorders because they are typically more severe and are not caused by FLNB gene mutations.

user: What is (are) carnitine palmitoyltransferase II deficiency ?

assistant: Carnitine palmitoyltransferase II (CPT II) deficiency is a condition that prevents the body from using certain fats for energy, particularly during periods without food (fasting). There are three main types of CPT II deficiency: a lethal neonatal form, a severe infantile hepatocardiomuscular form, and a myopathic form.  The lethal neonatal form of CPT II deficiency becomes apparent soon after birth. Infants with this form of the disorder develop respiratory failure, seizures, liver failure, a weakened heart muscle (cardiomyopathy), and an irregular heart beat (arrhythmia). Affected individuals also have low blood sugar (hypoglycemia) and a low level of ketones, which are produced during the breakdown of fats and used for energy. Together these signs are called hypoketotic hypoglycemia. In many cases, the brain and kidneys are also structurally abnormal. Infants with the lethal neonatal form of CPT II deficiency usually live for a few days to a few months.  The severe infantile hepatocardiomuscular form of CPT II deficiency affects the liver, heart, and muscles. Signs and symptoms usually appear within the first year of life. This form involves recurring episodes of hypoketotic hypoglycemia, seizures, an enlarged liver (hepatomegaly), cardiomyopathy, and arrhythmia. Problems related to this form of CPT II deficiency can be triggered by periods of fasting or by illnesses such as viral infections. Individuals with the severe infantile hepatocardiomuscular form of CPT II deficiency are at risk for liver failure, nervous system damage, coma, and sudden death.  The myopathic form is the least severe type of CPT II deficiency. This form is characterized by recurrent episodes of muscle pain (myalgia) and weakness and is associated with the breakdown of muscle tissue (rhabdomyolysis). The destruction of muscle tissue releases a protein called myoglobin, which is processed by the kidneys and released in the urine (myoglobinuria). Myoglobin causes the urine to be red or brown. This protein can also damage the kidneys, in some cases leading to life-threatening kidney failure. Episodes of myalgia and rhabdomyolysis may be triggered by exercise, stress, exposure to extreme temperatures, infections, or fasting. The first episode usually occurs during childhood or adolescence. Most people with the myopathic form of CPT II deficiency have no signs or symptoms of the disorder between episodes.
user: How many people are affected by carnitine palmitoyltransferase II deficiency ?

assistant: CPT II deficiency is a rare disorder. The lethal neonatal form has been described in at least 18 families, while the severe infantile hepatocardiomuscular form has been identified in approximately 30 families. The myopathic form occurs most frequently, with more than 300 reported cases.
user: What are the genetic changes related to carnitine palmitoyltransferase II deficiency ?

assistant: Mutations in the CPT2 gene cause CPT II deficiency. This gene provides instructions for making an enzyme called carnitine palmitoyltransferase 2. This enzyme is essential for fatty acid oxidation, which is the multistep process that breaks down (metabolizes) fats and converts them into energy. Fatty acid oxidation takes place within mitochondria, which are the energy-producing centers in cells. A group of fats called long-chain fatty acids must be attached to a substance known as carnitine to enter mitochondria. Once these fatty acids are inside mitochondria, carnitine palmitoyltransferase 2 removes the carnitine and prepares them for fatty acid oxidation. Fatty acids are a major source of energy for the heart and muscles. During periods of fasting, fatty acids are also an important energy source for the liver and other tissues.  Mutations in the CPT2 gene reduce the activity of carnitine palmitoyltransferase 2. Without enough of this enzyme, carnitine is not removed from long-chain fatty acids. As a result, these fatty acids cannot be metabolized to produce energy. Reduced energy production can lead to some of the features of CPT II deficiency, such as hypoketotic hypoglycemia, myalgia, and weakness. Fatty acids and long-chain acylcarnitines (fatty acids still attached to carnitine) may also build up in cells and damage the liver, heart, and muscles. This abnormal buildup causes the other signs and symptoms of the disorder.

user: What is (are) Bietti crystalline dystrophy ?

assistant: Bietti crystalline dystrophy is a disorder in which numerous small, yellow or white crystal-like deposits of fatty (lipid) compounds accumulate in the light-sensitive tissue that lines the back of the eye (the retina). The deposits damage the retina, resulting in progressive vision loss.  People with Bietti crystalline dystrophy typically begin noticing vision problems in their teens or twenties. They experience a loss of sharp vision (reduction in visual acuity) and difficulty seeing in dim light (night blindness). They usually lose areas of vision (visual field loss), most often side (peripheral) vision. Color vision may also be impaired.  The vision problems may worsen at different rates in each eye, and the severity and progression of symptoms varies widely among affected individuals, even within the same family. However, most people with this condition become legally blind by their forties or fifties. Most affected individuals retain some degree of vision, usually in the center of the visual field, although it is typically blurry and cannot be corrected by glasses or contact lenses. Vision impairment that cannot be improved with corrective lenses is called low vision.
user: How many people are affected by Bietti crystalline dystrophy ?

assistant: Bietti crystalline dystrophy has been estimated to occur in 1 in 67,000 people. It is more common in people of East Asian descent, especially those of Chinese and Japanese background. Researchers suggest that Bietti crystalline dystrophy may be underdiagnosed because its symptoms are similar to those of other eye disorders that progressively damage the retina.
user: What are the genetic changes related to Bietti crystalline dystrophy ?

assistant: Bietti crystalline dystrophy is caused by mutations in the CYP4V2 gene. This gene provides instructions for making a member of the cytochrome P450 family of enzymes. These enzymes are involved in the formation and breakdown of various molecules and chemicals within cells. The CYP4V2 enzyme is involved in a multi-step process called fatty acid oxidation in which lipids are broken down and converted into energy, but the enzyme's specific function is not well understood. CYP4V2 gene mutations that cause Bietti crystalline dystrophy impair or eliminate the function of this enzyme and are believed to affect lipid breakdown. However, it is unknown how they lead to the specific signs and symptoms of Bietti crystalline dystrophy. For unknown reasons, the severity of the signs and symptoms differs significantly among individuals with the same CYP4V2 gene mutation.
user: Is Bietti crystalline dystrophy inherited ?

assistant: 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.

user: What is (are) cold-induced sweating syndrome ?

assistant: Cold-induced sweating syndrome is characterized by problems with regulating body temperature and other abnormalities affecting many parts of the body. In infancy, the features of this condition are often known as Crisponi syndrome. Researchers originally thought that cold-induced sweating syndrome and Crisponi syndrome were separate disorders, but it is now widely believed that they represent the same condition at different times during life.  Infants with Crisponi syndrome have unusual facial features, including a flat nasal bridge, upturned nostrils, a long space between the nose and upper lip (philtrum), a high arched roof of the mouth (palate), a small chin (micrognathia), and low-set ears. The muscles in the lower part of the face are weak, leading to severe feeding difficulties, excessive drooling, and breathing problems. Other physical abnormalities associated with Crisponi syndrome include a scaly skin rash, an inability to fully extend the elbows, overlapping fingers and tightly fisted hands, and malformations of the feet and toes. Affected infants startle easily and often tense their facial muscles into a grimace-like expression. By six months of age, infants with Crisponi syndrome develop unexplained high fevers that increase the risk of seizures and sudden death.  Many of the health problems associated with Crisponi syndrome improve with time, and affected individuals who survive the newborn period go on to develop other features of cold-induced sweating syndrome in early childhood. Within the first decade of life, affected individuals begin having episodes of profuse sweating (hyperhidrosis) and shivering involving the face, torso, and arms. The excessive sweating is usually triggered by exposure to temperatures below about 65 or 70 degrees Fahrenheit, but it can also be triggered by nervousness or eating sugary foods. Paradoxically, affected individuals tend not to sweat in warmer conditions, instead becoming flushed and overheated in hot environments.  Adolescents with cold-induced sweating syndrome typically develop abnormal side-to-side and front-to-back curvature of the spine (scoliosis and kyphosis, often called kyphoscoliosis when they occur together). Although infants may develop life-threatening fevers, affected individuals who survive infancy have a normal life expectancy.
user: How many people are affected by cold-induced sweating syndrome ?

assistant: Cold-induced sweating syndrome is a rare condition; its prevalence is unknown. The condition was first identified in the Sardinian population, but it has since been reported in regions worldwide.
user: What are the genetic changes related to cold-induced sweating syndrome ?

assistant: About 90 percent of cases of cold-induced sweating syndrome and Crisponi syndrome result from mutations in the CRLF1 gene. These cases are designated as CISS1. The remaining 10 percent of cases are caused by mutations in the CLCF1 gene and are designated as CISS2.  The proteins produced from the CRLF1 and CLCF1 genes work together as part of a signaling pathway that is involved in the normal development of the nervous system. This pathway appears to be particularly important for the development and maintenance of motor neurons, which are nerve cells that control muscle movement. Studies suggest that this pathway also has a role in a part of the nervous system known as the sympathetic nervous system, specifically in the regulation of sweating in response to temperature changes and other factors. The proteins produced from the CRLF1 and CLCF1 genes appear to be critical for the normal development and maturation of nerve cells that control the activity of sweat glands.  Additionally, the CRLF1 and CLCF1 genes likely have functions outside the nervous system, including roles in the body's inflammatory response and in bone development. However, little is known about their involvement in these processes.  Mutations in either the CRLF1 or CLCF1 gene disrupt the normal development of several body systems, including the nervous system. The role of these genes in sympathetic nervous system development may help explain the abnormal sweating that is characteristic of this condition, including unusual sweating patterns and related problems with body temperature regulation. The involvement of these genes in motor neuron development and bone development provides clues to some of the other signs and symptoms of cold-induced sweating syndrome, including distinctive facial features, facial muscle weakness, and skeletal abnormalities. However, little is known about how CRLF1 or CLCF1 gene mutations underlie these other features of cold-induced sweating syndrome.
user: Is cold-induced sweating syndrome inherited ?

assistant: Cold-induced sweating syndrome is inherited in anautosomal recessive pattern, which means both copies of the CRLF1 or CLCF1 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.

user: What is (are) spinal and bulbar muscular atrophy ?

assistant: Spinal and bulbar muscular atrophy, also known as Kennedy disease, is a disorder of specialized nerve cells that control muscle movement (motor neurons). These nerve cells originate in the spinal cord and the part of the brain that is connected to the spinal cord (the brainstem).  Spinal and bulbar muscular atrophy mainly affects males and is characterized by muscle weakness and wasting (atrophy) that usually begins in adulthood and worsens slowly over time. Muscle wasting in the arms and legs results in cramping; leg muscle weakness can also lead to difficulty walking and a tendency to fall. Certain muscles in the face and throat (bulbar muscles) are also affected, which causes progressive problems with swallowing and speech. Additionally, muscle twitches (fasciculations) are common. Some males with the disorder experience unusual breast development (gynecomastia) and may be unable to father a child (infertile).
user: How many people are affected by spinal and bulbar muscular atrophy ?

assistant: This condition affects fewer than 1 in 150,000 males and is very rare in females.
user: What are the genetic changes related to spinal and bulbar muscular atrophy ?

assistant: Spinal and bulbar muscular atrophy results from a particular type of mutation in the AR gene. This gene provides instructions for making a protein called an androgen receptor. This receptor attaches (binds) to a class of hormones called androgens, which are involved in male sexual development. Androgens and androgen receptors also have other important functions in both males and females, such as regulating hair growth and sex drive.  The AR gene mutation that causes spinal and bulbar muscular atrophy is the abnormal expansion of a DNA segment called a CAG triplet repeat. Normally, this DNA segment is repeated up to about 36 times. In people with spinal and bulbar muscular atrophy, the CAG segment is repeated at least 38 times, and it may be two or three times its usual length. Although the extended CAG region changes the structure of the androgen receptor, it is unclear how the altered protein disrupts nerve cells in the brain and spinal cord. Researchers believe that a fragment of the androgen receptor protein containing the CAG segment accumulates within these cells and interferes with normal cell functions. The nerve cells gradually die, leading to the muscle weakness and wasting seen in this condition. People with a higher number of CAG repeats tend to develop signs and symptoms of spinal and bulbar muscular atrophy at an earlier age.
user: Is spinal and bulbar muscular atrophy inherited ?

assistant: 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 males (who have only one X chromosome), a mutation in the only copy of the gene in each cell causes the disorder. In most cases, males experience more severe symptoms of the disorder than females (who have two X chromosomes). Females with a mutation in one copy of the AR gene in each cell are typically unaffected. A few females with mutations in both copies of the gene have had mild features related to the condition, including muscle cramps and occasional tremors. Researchers believe that the milder signs and symptoms in females may be related to lower androgen levels.  A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.

user: What is (are) Cowden syndrome ?

assistant: Cowden syndrome is a disorder characterized by multiple noncancerous, tumor-like growths called hamartomas and an increased risk of developing certain cancers.  Almost everyone with Cowden syndrome develops hamartomas. These growths are most commonly found on the skin and mucous membranes (such as the lining of the mouth and nose), but they can also occur in the intestine and other parts of the body. The growth of hamartomas on the skin and mucous membranes typically becomes apparent by a person's late twenties.  Cowden syndrome is associated with an increased risk of developing several types of cancer, particularly cancers of the breast, a gland in the lower neck called the thyroid, and the lining of the uterus (the endometrium). Other cancers that have been identified in people with Cowden syndrome include colorectal cancer, kidney cancer, and a form of skin cancer called melanoma. Compared with the general population, people with Cowden syndrome develop these cancers at younger ages, often beginning in their thirties or forties. Other diseases of the breast, thyroid, and endometrium are also common in Cowden syndrome. Additional signs and symptoms can include an enlarged head (macrocephaly) and a rare, noncancerous brain tumor called Lhermitte-Duclos disease. A small percentage of affected individuals have delayed development or intellectual disability.  The features of Cowden syndrome overlap with those of another disorder called Bannayan-Riley-Ruvalcaba syndrome. People with Bannayan-Riley-Ruvalcaba syndrome also develop hamartomas and other noncancerous tumors. Both conditions can be caused by mutations in the PTEN gene. Some people with Cowden syndrome have had relatives diagnosed with Bannayan-Riley-Ruvalcaba syndrome, and other individuals have had the characteristic features of both conditions. Based on these similarities, researchers have proposed that Cowden syndrome and Bannayan-Riley-Ruvalcaba syndrome represent a spectrum of overlapping features known as PTEN hamartoma tumor syndrome instead of two distinct conditions.  Some people have some of the characteristic features of Cowden syndrome, particularly the cancers associated with this condition, but do not meet the strict criteria for a diagnosis of Cowden syndrome. These individuals are often described as having Cowden-like syndrome.
user: How many people are affected by Cowden syndrome ?

assistant: Although the exact prevalence of Cowden syndrome is unknown, researchers estimate that it affects about 1 in 200,000 people.
