Huntingtonism (triad of progressive movement disorder and cognitive and behavioral alterations) is a typical presentation. Phenotypic variability is considerable even within the same family, including for monozygotic twins. Mean age of onset is about 30 years. VPS13A disease runs a chronic progressive course and may lead to major disability within a few years. Some affected individuals are bedridden or wheelchair dependent by the third decade. Age at death ranges from 28 to 61 years; several instances of sudden unexplained death or death during epileptic seizures have been reported." /><meta name="robots" content="index,nofollow,noarchive" />

Huntingtonism (triad of progressive movement disorder and cognitive and behavioral alterations) is a typical presentation. Phenotypic variability is considerable even within the same family, including for monozygotic twins. Mean age of onset is about 30 years. VPS13A disease runs a chronic progressive course and may lead to major disability within a few years. Some affected individuals are bedridden or wheelchair dependent by the third decade. Age at death ranges from 28 to 61 years; several instances of sudden unexplained death or death during epileptic seizures have been reported. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1387#chac.Summary" target="NBK1387">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Diagnosis" target="NBK1387">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Clinical_Characteristics" target="NBK1387">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Genetically_Related_Allelic_Disorde" target="NBK1387">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Differential_Diagnosis" target="NBK1387">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Management" target="NBK1387">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Genetic_Counseling" target="NBK1387">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Resources" target="NBK1387">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Molecular_Genetics" target="NBK1387">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.Chapter_Notes" target="NBK1387">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1387#chac.References" target="NBK1387">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Choreoacanthocytosis (CHAC) is an autosomal recessive disorder characterized by progressive neurodegeneration and red cell acanthocytosis, with onset in the third to fifth decade of life (Rubio et al., 1997).&#13;
See also McLeod syndrome (300842) for a phenotypically similar disorder.  <a target="_blank" href="http://www.omim.org/entry/200150">http://www.omim.org/entry/200150</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Chorea-acanthocytosis is primarily a neurological disorder that affects movement in many parts of the body. Chorea refers to the involuntary jerking movements made by people with this disorder. People with this condition also have abnormal star-shaped red blood cells (acanthocytosis). This condition is one of a group of conditions called neuroacanthocytoses that involve neurological problems and abnormal red blood cells.<br /><br />In addition to chorea, another common feature of chorea-acanthocytosis is involuntary tensing of various muscles (dystonia), such as those in the limbs, face, mouth, tongue, and throat. These muscle twitches can cause vocal tics (such as grunting), involuntary belching, and limb spasms. Eating can also be impaired as tongue and throat twitches can interfere with chewing and swallowing food. People with chorea-acanthocytosis may uncontrollably bite their tongue, lips, and inside of the mouth. Nearly half of all people with chorea-acanthocytosis have seizures.<br /><br />Individuals with chorea-acanthocytosis may develop difficulty processing, learning, and remembering information (cognitive impairment). They may have reduced sensation and weakness in their arms and legs (peripheral neuropathy) and muscle weakness (myopathy). Impaired muscle and nerve functioning commonly cause speech difficulties in individuals with this condition, and can lead to an inability to speak.<br /><br />Behavioral changes are a common feature of chorea-acanthocytosis and may be the first sign of this condition. These behavioral changes may include changes in personality, obsessive-compulsive disorder (OCD), lack of self-restraint, and the inability to take care of oneself.<br /><br />The signs and symptoms of chorea-acanthocytosis usually begin in early to mid-adulthood. The movement problems of this condition worsen with age. Loss of cells (atrophy) in certain brain regions is the major cause of the neurological problems seen in people with chorea-acanthocytosis.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/chorea-acanthocytosis">https://medlineplus.gov/genetics/condition/chorea-acanthocytosis</a></div></div>

<div class="spaceAbove">Chorea (Greek for 'dance') refers to widespread arrhythmic involuntary movements of a forcible, jerky and restless fashion. It is a random-appearing sequence of one or more discrete involuntary movements or movement fragments. Movements appear random because of variability in timing, duration or location. Each movement may have a distinct start and end. However, movements may be strung together and thus may appear to flow randomly from one muscle group to another. Chorea can involve the trunk, neck, face, tongue, and extremities.</div>
