Question: How many people are affected by horizontal gaze palsy with progressive scoliosis ?
Answer: HGPPS has been reported in several dozen families worldwide.
Question: What are the genetic changes related to horizontal gaze palsy with progressive scoliosis ?
Answer: HGPPS is caused by mutations in the ROBO3 gene. This gene provides instructions for making a protein that is important for the normal development of certain nerve pathways in the brain. These include motor nerve pathways, which transmit information about voluntary muscle movement, and sensory nerve pathways, which transmit information about sensory input (such as touch, pain, and temperature). For the brain and the body to communicate effectively, these nerve pathways must cross from one side of the body to the other in the brainstem, a region that connects the upper parts of the brain with the spinal cord. The ROBO3 protein plays a critical role in ensuring that motor and sensory nerve pathways cross over in the brainstem. In people with HGPPS, these pathways do not cross over, but stay on the same side of the body. Researchers believe that this miswiring in the brainstem is the underlying cause of the eye movement abnormalities associated with the disorder. The cause of progressive scoliosis in HGPPS is unclear. Researchers are working to determine why the effects of ROBO3 mutations appear to be limited to horizontal eye movement and scoliosis.
Question: Is horizontal gaze palsy with progressive scoliosis 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) familial restrictive cardiomyopathy ?
Answer: Familial restrictive cardiomyopathy is a genetic form of heart disease. For the heart to beat normally, the heart (cardiac) muscle must contract and relax in a coordinated way. Oxygen-rich blood from the lungs travels first through the upper chambers of the heart (the atria), and then to the lower chambers of the heart (the ventricles). In people with familial restrictive cardiomyopathy, the heart muscle is stiff and cannot fully relax after each contraction. Impaired muscle relaxation causes blood to back up in the atria and lungs, which reduces the amount of blood in the ventricles. Familial restrictive cardiomyopathy can appear anytime from childhood to adulthood. The first signs and symptoms of this condition in children are failure to gain weight and grow at the expected rate (failure to thrive), extreme tiredness (fatigue), and fainting. Children who are severely affected may also have abnormal swelling or puffiness (edema), increased blood pressure, an enlarged liver, an abnormal buildup of fluid in the abdominal cavity (ascites), and lung congestion. Some children with familial restrictive cardiomyopathy do not have any obvious signs or symptoms, but they may die suddenly due to heart failure. Without treatment, the majority of affected children survive only a few years after they are diagnosed. Adults with familial restrictive cardiomyopathy typically first develop shortness of breath, fatigue, and a reduced ability to exercise. Some individuals have an irregular heart beat (arrhythmia) and may also experience a sensation of fluttering or pounding in the chest (palpitations) and dizziness. Abnormal blood clots are commonly seen in adults with this condition. Without treatment, approximately one-third of adults with familial restrictive cardiomyopathy do not survive more than five years after diagnosis.
Question: How many people are affected by familial restrictive cardiomyopathy ?
Answer: The prevalence of familial restrictive cardiomyopathy is unknown. Although cardiomyopathy is a relatively common condition, restrictive cardiomyopathy, in which relaxation of the heart muscle is impaired, is the least common type. Some other forms of cardiomyopathy involve a weak or enlarged heart muscle with impaired contraction. In the United States and in Europe, restrictive cardiomyopathy accounts for less than five percent of all cardiomyopathies. The proportion of restrictive cardiomyopathy that runs in families is not known.
Question: What are the genetic changes related to familial restrictive cardiomyopathy ?
Answer: Mutations in several genes have been found to cause familial restrictive cardiomyopathy. Mutations in the TNNI3 gene are one of the major causes of this condition. The TNNI3 gene provides instructions for making a protein called cardiac troponin I, which is found solely in the heart. Cardiac troponin I is one of three proteins that make up the troponin protein complex, which helps regulate tensing (contraction) and relaxation of the heart muscle. TNNI3 gene mutations associated with familial restrictive cardiomyopathy result in the production of a defective cardiac troponin I protein. The altered protein disrupts the function of the troponin protein complex and does not allow the heart muscle to fully relax. As a result, not enough blood enters the ventricles, leading to a buildup in the atria and lungs. The abnormal heart relaxation and blood flow is responsible for many of the signs and symptoms of familial restrictive cardiomyopathy. Mutations in other genes associated with familial restrictive cardiomyopathy each account for a small percentage of cases of this condition. Some people with familial restrictive cardiomyopathy do not have an identified mutation in any of the known associated genes. The cause of the disorder in these individuals is unknown.
Question: Is familial restrictive cardiomyopathy 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.

Question: What is (are) early-onset glaucoma ?
Answer: Glaucoma is a group of eye disorders in which the optic nerves connecting the eyes and the brain are progressively damaged. This damage can lead to reduction in side (peripheral) vision and eventual blindness. Other signs and symptoms may include bulging eyes, excessive tearing, and abnormal sensitivity to light (photophobia). The term "early-onset glaucoma" may be used when the disorder appears before the age of 40. In most people with glaucoma, the damage to the optic nerves is caused by increased pressure within the eyes (intraocular pressure). Intraocular pressure depends on a balance between fluid entering and leaving the eyes. Usually glaucoma develops in older adults, in whom the risk of developing the disorder may be affected by a variety of medical conditions including high blood pressure (hypertension) and diabetes mellitus, as well as family history. The risk of early-onset glaucoma depends mainly on heredity. Structural abnormalities that impede fluid drainage in the eye may be present at birth and usually become apparent during the first year of life. Such abnormalities may be part of a genetic disorder that affects many body systems, called a syndrome. If glaucoma appears before the age of 5 without other associated abnormalities, it is called primary congenital glaucoma. Other individuals experience early onset of primary open-angle glaucoma, the most common adult form of glaucoma. If primary open-angle glaucoma develops during childhood or early adulthood, it is called juvenile open-angle glaucoma.
Question: How many people are affected by early-onset glaucoma ?
Answer: Primary congenital glaucoma affects approximately 1 in 10,000 people. Its frequency is higher in the Middle East. Juvenile open-angle glaucoma affects about 1 in 50,000 people. Primary open-angle glaucoma is much more common after the age of 40, affecting about 1 percent of the population worldwide.
Question: What are the genetic changes related to early-onset glaucoma ?
Answer: Approximately 10 percent to 33 percent of people with juvenile open-angle glaucoma have mutations in the MYOC gene. MYOC gene mutations have also been detected in some people with primary congenital glaucoma. The MYOC gene provides instructions for producing a protein called myocilin. Myocilin is found in certain structures of the eye, called the trabecular meshwork and the ciliary body, that regulate the intraocular pressure. Researchers believe that myocilin functions together with other proteins as part of a protein complex. Mutations may alter the protein in such a way that the complex cannot be formed. Defective myocilin that is not incorporated into functional complexes may accumulate in the trabecular meshwork and ciliary body. The excess protein may prevent sufficient flow of fluid from the eye, resulting in increased intraocular pressure and causing the signs and symptoms of early-onset glaucoma. Between 20 percent and 40 percent of people with primary congenital glaucoma have mutations in the CYP1B1 gene. CYP1B1 gene mutations have also been detected in some people with juvenile open-angle glaucoma. The CYP1B1 gene provides instructions for producing a form of the cytochrome P450 protein. Like myocilin, this protein is found in the trabecular meshwork, ciliary body, and other structures of the eye. It is not well understood how defects in the CYP1B1 protein cause signs and symptoms of glaucoma. Recent studies suggest that the defects may interfere with the early development of the trabecular meshwork. In the clear covering of the eye (the cornea), the CYP1B1 protein may also be involved in a process that regulates the secretion of fluid inside the eye. If this fluid is produced in excess, the high intraocular pressure characteristic of glaucoma may develop. The CYP1B1 protein may interact with myocilin. Individuals with mutations in both the MYOC and CYP1B1 genes may develop glaucoma at an earlier age and have more severe symptoms than do those with mutations in only one of the genes. Mutations in other genes may also be involved in early-onset glaucoma.
Question: Is early-onset glaucoma inherited ?
Answer: Early-onset glaucoma can have different inheritance patterns. Primary congenital glaucoma is usually inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show signs and symptoms of the condition. Juvenile open-angle glaucoma 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 families, primary congenital glaucoma may also be inherited in an autosomal dominant pattern.

Question: What is (are) oculopharyngeal muscular dystrophy ?
Answer: Oculopharyngeal muscular dystrophy is a genetic condition characterized by muscle weakness that begins in adulthood, typically after age 40. The first symptom in people with this disorder is usually droopy eyelids (ptosis), followed by difficulty swallowing (dysphagia). The swallowing difficulties begin with food, but as the condition progresses, liquids can be difficult to swallow as well. Many people with this condition have weakness and wasting (atrophy) of the tongue. These problems with food intake may cause malnutrition. Some affected individuals also have weakness in other facial muscles. Individuals with oculopharyngeal muscular dystrophy frequently have weakness in the muscles near the center of the body (proximal muscles), particularly muscles in the upper legs and hips. The weakness progresses slowly over time, and people may need the aid of a cane or a walker. Rarely, affected individuals need wheelchair assistance. There are two types of oculopharyngeal muscular dystrophy, which are distinguished by their pattern of inheritance. They are known as the autosomal dominant and autosomal recessive types.
Question: How many people are affected by oculopharyngeal muscular dystrophy ?
Answer: In Europe, the prevalence of oculopharyngeal muscular dystrophy is estimated to be 1 in 100,000 people. The autosomal dominant form of this condition is much more common in the French-Canadian population of the Canadian province of Quebec, where it is estimated to affect 1 in 1,000 individuals. Autosomal dominant oculopharyngeal muscular dystrophy is also seen more frequently in the Bukharan (Central Asian) Jewish population of Israel, affecting 1 in 600 people. The autosomal recessive form of this condition is very rare; only a few cases of autosomal recessive oculopharyngeal muscular dystrophy have been identified.
Question: What are the genetic changes related to oculopharyngeal muscular dystrophy ?
Answer: Mutations in the PABPN1 gene cause oculopharyngeal muscular dystrophy. The PABPN1 gene provides instructions for making a protein that is active (expressed) throughout the body. In cells, the PABPN1 protein plays an important role in processing molecules called messenger RNAs (mRNAs), which serve as genetic blueprints for making proteins. The protein alters a region at the end of the mRNA molecule that protects the mRNA from being broken down and allows it to move within the cell. The PABPN1 protein contains an area where the protein building block (amino acid) alanine is repeated 10 times. This stretch of alanines is known as a polyalanine tract. The role of the polyalanine tract in normal PABPN1 protein function is unknown. Mutations in the PABPN1 gene that cause oculopharyngeal muscular dystrophy result in a PABPN1 protein that has an extended polyalanine tract. The extra alanines cause the PABPN1 protein to form clumps within muscle cells that accumulate because they cannot be broken down. These clumps (called intranuclear inclusions) are thought to impair the normal functioning of muscle cells and eventually cause cell death. The progressive loss of muscle cells most likely causes the muscle weakness seen in people with oculopharyngeal muscular dystrophy. It is not known why dysfunctional PABPN1 proteins seem to affect only certain muscle cells.
Question: Is oculopharyngeal muscular dystrophy inherited ?
Answer: Most cases of oculopharyngeal muscular dystrophy are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. People with autosomal dominant oculopharyngeal muscular dystrophy have a mutation resulting in a PABPN1 protein with an expanded polyalanine tract of between 12 and 17 alanines. Less commonly, oculopharyngeal muscular dystrophy can be inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. In autosomal recessive oculopharyngeal muscular dystrophy, PABPN1 mutations lead to a polyalanine tract that is 11 alanines long. 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) late-infantile neuronal ceroid lipofuscinosis ?
Answer: Late-infantile neuronal ceroid lipofuscinosis (NCL) is an inherited disorder that primarily affects the nervous system. The signs and symptoms of this condition typically begin in late infancy or early childhood. The initial features usually include recurrent seizures (epilepsy) and difficulty coordinating movements (ataxia). Affected children also develop muscle twitches (myoclonus) and vision impairment. Late-infantile NCL affects motor skills, such as sitting and walking, and speech development. This condition also causes the loss of previously acquired skills (developmental regression), progressive intellectual disability, and behavioral problems. Individuals with this condition often require the use of a wheelchair by late childhood and typically do not survive past their teens. Late-infantile NCL is one of a group of NCLs (collectively called Batten disease) that affect the nervous system and typically cause progressive problems with vision, movement, and thinking ability. The different types of NCLs are distinguished by the age at which signs and symptoms first appear.
Question: How many people are affected by late-infantile neuronal ceroid lipofuscinosis ?
Answer: The prevalence of late-infantile NCL is unknown. Collectively, all forms of NCL affect an estimated 1 in 100,000 individuals worldwide. NCLs are more common in Finland, where approximately 1 in 12,500 individuals are affected.
Question: What are the genetic changes related to late-infantile neuronal ceroid lipofuscinosis ?
Answer: Mutations in the TPP1 gene cause most cases of late-infantile NCL. Mutations in the CLN5, CLN6, CLN8, MFSD8, and PPT1 genes each account for a small percentage of cases. The TPP1 gene produces an enzyme called tripeptidyl peptidase 1. This enzyme is found in cell structures called lysosomes, which digest and recycle different types of molecules. Tripeptidyl peptidase 1 breaks down protein fragments, known as peptides, into their individual building blocks (amino acids). The proteins produced from the other genes involved in this condition are active either in lysosomes or in another cell compartment called the endoplasmic reticulum. The endoplasmic reticulum is involved in protein production, processing, and transport. Within these cell structures, the proteins largely play roles in the breakdown of other proteins or substances. Mutations in the TPP1, CLN5, CLN6, CLN8, MFSD8, or PPT1 gene usually reduce the production or activity of the particular protein or enzyme made from the gene. In many cases, a reduction in functional protein or enzyme results in incomplete breakdown of certain proteins and other materials. These materials accumulate in the lysosome forming fatty substances called lipopigments. In some cases, it is unclear what causes the buildup of lipopigments. In late-infantile NCL, these accumulations occur in cells throughout the body, but neurons seem particularly vulnerable to damage caused by lipopigments and a decrease in specific protein function. The progressive death of cells in the brain and other tissues leads to the signs and symptoms of late-infantile NCL.
Question: Is late-infantile neuronal ceroid lipofuscinosis 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) adenine phosphoribosyltransferase deficiency ?
Answer: Adenine phosphoribosyltransferase (APRT) deficiency is an inherited condition that affects the kidneys and urinary tract. The most common feature of this condition is recurrent kidney stones; urinary tract stones are also a frequent symptom. Kidney and urinary tract stones can create blockages in the urinary tract, causing pain during urination and difficulty releasing urine. Affected individuals can develop features of this condition anytime from infancy to late adulthood. When the condition appears in infancy, the first sign is usually the presence of tiny grains of reddish-brown material in the baby's diaper caused by the passing of stones. Later, recurrent kidney and urinary tract stones can lead to problems with kidney function beginning as early as mid- to late childhood. Approximately half of individuals with APRT deficiency first experience signs and symptoms of the condition in adulthood. The first features in affected adults are usually kidney stones and related urinary problems. Other signs and symptoms of APRT deficiency caused by kidney and urinary tract stones include fever, urinary tract infection, blood in the urine (hematuria), abdominal cramps, nausea, and vomiting. Without treatment, kidney function can decline, which may lead to end-stage renal disease (ESRD). ESRD is a life-threatening failure of kidney function that occurs when the kidneys are no longer able to filter fluids and waste products from the body effectively. The features of this condition and their severity vary greatly among affected individuals, even among members of the same family. It is estimated that 15 to 20 percent of people with APRT deficiency do not have any signs or symptoms of the condition.
Question: How many people are affected by adenine phosphoribosyltransferase deficiency ?
Answer: APRT deficiency is estimated to affect 1 in 27,000 people in Japan. The condition is rarer in Europe, where it is thought to affect 1 in 50,000 to 100,000 people. The prevalence of APRT deficiency outside these populations is unknown.
