Is early-onset glaucoma inherited ?
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. + GHR + early-onset glaucoma

What is (are) oculopharyngeal muscular dystrophy ?
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. + GHR + oculopharyngeal muscular dystrophy
How many people are affected by oculopharyngeal muscular dystrophy ?
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. + GHR + oculopharyngeal muscular dystrophy
What are the genetic changes related to oculopharyngeal muscular dystrophy ?
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. + GHR + oculopharyngeal muscular dystrophy
Is oculopharyngeal muscular dystrophy inherited ?
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. + GHR + oculopharyngeal muscular dystrophy

What is (are) late-infantile neuronal ceroid lipofuscinosis ?
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. + GHR + late-infantile neuronal ceroid lipofuscinosis
How many people are affected by late-infantile neuronal ceroid lipofuscinosis ?
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. + GHR + late-infantile neuronal ceroid lipofuscinosis
What are the genetic changes related to late-infantile neuronal ceroid lipofuscinosis ?
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. + GHR + late-infantile neuronal ceroid lipofuscinosis

What is (are) adenine phosphoribosyltransferase deficiency ?
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. + GHR + adenine phosphoribosyltransferase deficiency
How many people are affected by adenine phosphoribosyltransferase deficiency ?
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. + GHR + adenine phosphoribosyltransferase deficiency
What are the genetic changes related to adenine phosphoribosyltransferase deficiency ?
Mutations in the APRT gene cause APRT deficiency. This gene provides instructions for making APRT, an enzyme that helps to convert a DNA building block (nucleotide) called adenine to a molecule called adenosine monophosphate (AMP). This conversion occurs when AMP is needed as a source of energy for cells.  APRT gene mutations lead to the production of an abnormal APRT enzyme with reduced function or prevent the production of any enzyme. A lack of functional enzyme impairs the conversion of adenine to AMP. As a result, adenine is converted to another molecule called 2,8-dihydroxyadenine (2,8-DHA). 2,8-DHA crystallizes in urine, forming stones in the kidneys and urinary tract. 2,8-DHA crystals are brownish in color, which explains why affected infants frequently have dark urine stains in their diapers. 2,8-DHA is toxic to kidneys, which may explain the possible decline in kidney function and the progression to ESRD. + GHR + adenine phosphoribosyltransferase deficiency

What is (are) familial paroxysmal nonkinesigenic dyskinesia ?
Familial paroxysmal nonkinesigenic dyskinesia is a disorder of the nervous system that causes periods of involuntary movement. Paroxysmal indicates that the abnormal movements come and go over time. Nonkinesigenic means that episodes are not triggered by sudden movement. Dyskinesia broadly refers to involuntary movement of the body.  People with familial paroxysmal nonkinesigenic dyskinesia experience episodes of abnormal movement that develop without a known cause or are brought on by alcohol, caffeine, stress, fatigue, menses, or excitement. Episodes are not induced by exercise or sudden movement and do not occur during sleep. An episode is characterized by irregular, jerking or shaking movements that range from mild to severe. In this disorder, the dyskinesias can include slow, prolonged contraction of muscles (dystonia); small, fast, "dance-like" motions (chorea); writhing movements of the limbs (athetosis); and, rarely, flailing movements of the limbs (ballismus). Dyskinesias also affect muscles in the trunk and face. The type of abnormal movement varies among affected individuals, even among members of the same family. Individuals with familial paroxysmal nonkinesigenic dyskinesia do not lose consciousness during an episode. Most people do not experience any other neurological symptoms between episodes.  Individuals with familial paroxysmal nonkinesigenic dyskinesia usually begin to show signs and symptoms of the disorder during childhood or their early teens. Episodes typically last 1-4 hours, and the frequency of episodes ranges from several per day to one per year. In some affected individuals, episodes occur less often with age. + GHR + familial paroxysmal nonkinesigenic dyskinesia
How many people are affected by familial paroxysmal nonkinesigenic dyskinesia ?
Familial paroxysmal nonkinesigenic dyskinesia is a very rare disorder. Its prevalence is estimated to be 1 in 5 million people. + GHR + familial paroxysmal nonkinesigenic dyskinesia
What are the genetic changes related to familial paroxysmal nonkinesigenic dyskinesia ?
Mutations in the PNKD gene cause familial paroxysmal nonkinesigenic dyskinesia. The function of the protein produced from the PNKD gene is unknown; however, it is similar to a protein that helps break down a chemical called methylglyoxal. Methylglyoxal is found in alcoholic beverages, coffee, tea, and cola. Research has demonstrated that this chemical has a toxic effect on nerve cells (neurons). It remains unclear if the PNKD gene is related to the breakdown of methlglyoxal. How mutations in the PNKD gene lead to the signs and symptoms of familial paroxysmal nonkinesigenic dyskinesia is also unknown. + GHR + familial paroxysmal nonkinesigenic dyskinesia
Is familial paroxysmal nonkinesigenic dyskinesia inherited ?
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is typically sufficient to cause the disorder. Almost everyone with a mutation in the PNKD gene will develop familial paroxysmal nonkinesigenic dyskinesia. In all reported cases, an affected person has inherited the mutation from one parent. + GHR + familial paroxysmal nonkinesigenic dyskinesia

What is (are) CHARGE syndrome ?
CHARGE syndrome is a disorder that affects many areas of the body. CHARGE stands for coloboma, heart defect, atresia choanae (also known as choanal atresia), retarded growth and development, genital abnormality, and ear abnormality. The pattern of malformations varies among individuals with this disorder, and infants often have multiple life-threatening medical conditions. The diagnosis of CHARGE syndrome is based on a combination of major and minor characteristics.  The major characteristics of CHARGE syndrome are more specific to this disorder than are the minor characteristics. Many individuals with CHARGE syndrome have a hole in one of the structures of the eye (coloboma), which forms during early development. A coloboma may be present in one or both eyes and can affect a person's vision, depending on its size and location. Some people also have small eyes (microphthalmia). One or both nasal passages may be narrowed (choanal stenosis) or completely blocked (choanal atresia). Individuals with CHARGE syndrome frequently have cranial nerve abnormalities. The cranial nerves emerge directly from the brain and extend to various areas of the head and neck, controlling muscle movement and transmitting sensory information. Abnormal function of certain cranial nerves can cause swallowing problems, facial paralysis, a sense of smell that is diminished (hyposmia) or completely absent (anosmia), and mild to profound hearing loss. People with CHARGE syndrome also typically have middle and inner ear abnormalities and unusually shaped ears.  The minor characteristics of CHARGE syndrome are not specific to this disorder; they are frequently present in people without CHARGE syndrome. The minor characteristics include heart defects, slow growth starting in late infancy, developmental delay, and an opening in the lip (cleft lip) with or without an opening in the roof of the mouth (cleft palate). Individuals frequently have hypogonadotropic hypogonadism, which affects the production of hormones that direct sexual development. Males are often born with an unusually small penis (micropenis) and undescended testes (cryptorchidism). External genitalia abnormalities are seen less often in females with CHARGE syndrome. Puberty can be incomplete or delayed. Individuals may have a tracheoesophageal fistula, which is an abnormal connection (fistula) between the esophagus and the trachea. People with CHARGE syndrome also have distinctive facial features, including a square-shaped face and difference in the appearance between the right and left sides of the face (facial asymmetry). Individuals have a wide range of cognitive function, from normal intelligence to major learning disabilities with absent speech and poor communication. + GHR + CHARGE syndrome
How many people are affected by CHARGE syndrome ?
CHARGE syndrome occurs in approximately 1 in 8,500 to 10,000 individuals. + GHR + CHARGE syndrome
What are the genetic changes related to CHARGE syndrome ?
Mutations in the CHD7 gene cause more than half of all cases of CHARGE syndrome. The CHD7 gene provides instructions for making a protein that most likely regulates gene activity (expression) by a process known as chromatin remodeling. Chromatin is the complex of DNA and protein that packages DNA into chromosomes. The structure of chromatin can be changed (remodeled) to alter how tightly DNA is packaged. Chromatin remodeling is one way gene expression is regulated during development. When DNA is tightly packed, gene expression is lower than when DNA is loosely packed.  Most mutations in the CHD7 gene lead to the production of an abnormally short, nonfunctional CHD7 protein, which presumably disrupts chromatin remodeling and the regulation of gene expression. Changes in gene expression during embryonic development likely cause the signs and symptoms of CHARGE syndrome.  About one-third of individuals with CHARGE syndrome do not have an identified mutation in the CHD7 gene. Researchers suspect that other genetic and environmental factors may be involved in these individuals. + GHR + CHARGE syndrome
Is CHARGE syndrome inherited ?
CHARGE syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases result from new mutations in the CHD7 gene and occur in people with no history of the disorder in their family. In rare cases, an affected person inherits the mutation from an affected parent. + GHR + CHARGE syndrome
