NIH Rare Diseases:42 Spinocerebellar ataxia 3 is a rare movement disorder that is characterized by ataxia, clumsiness and weakness in the arms and legs, spasticity, a staggering lurching walk easily mistaken for drunkenness, difficulty with speech and swallowing, involuntary eye movements, double vision, and frequent urination. some patients have dystonia or symptoms similar to those of parkinson's disease. others have twitching of the face or tongue, or bulging eyes. symptoms can begin any time between early adolescence and about 70 years of age. spinocerebellar ataxia 3 is a progressive disease, meaning that symptoms get worse with time. life expectancy ranges from the mid-thirties for those with severe forms of the disorder to a normal life expectancy for those with mild forms. spinocerebellar ataxia is inherited in an autosomal dominant pattern and is caused by a trinucleotide repeat expansion in the ataxin-3 gene (atxn3). last updated: 5/5/2009

MalaCards: Spinocerebellar Ataxia Type 3, also known as machado-joseph disease, is related to spinocerebellar ataxia and dentatorubral-pallidoluysian atrophy. An important gene associated with Spinocerebellar Ataxia Type 3 is ATXN3 (ataxin 3), and among its related pathways are Proteolysis Putative ubiquitin pathway and Transcriptional activity of SMAD2/SMAD3:SMAD4 heterotrimer. The compounds ndga and buthionine sulfoximine have been mentioned in the context of this disorder. Affiliated tissues include eye, tongue and brain.

Genetics Home Reference:21 Spinocerebellar ataxia type 3 (SCA3) is a condition characterized by progressive problems with movement. People with this condition initially experience problems with coordination and balance (ataxia). Other early signs and symptoms of SCA3 include speech difficulties, uncontrolled muscle tensing (dystonia), muscle stiffness (spasticity), rigidity, tremors, bulging eyes, and double vision. People with this condition may experience sleep disorders such as restless leg syndrome or REM sleep behavior disorder. Restless leg syndrome is a condition characterized by numbness or tingling in the legs accompanied by an urge to move the legs to stop the sensations. REM sleep behavior disorder is a condition in which the muscles are active during the dream (REM) stage of sleep, so an affected person often acts out his or her dreams. These sleep disorders tend to leave affected individuals feeling tired during the day.

NINDS:43 Machado-Joseph disease (MJD), which is also called spinocerebellar ataxia type 3, is a rare hereditary ataxia (ataxia is a medical term meaning lack of muscle control). The disease is characterized by slowly progressive clumsiness and weakness in the arms and legs, spasticity, a staggering lurching gait easily mistaken for drunkenness, difficulty with speech and swallowing, involuntary eye movements, double vision, and frequent urination. Some individuals also have dystonia (sustained muscle contractions that cause twisting of the body and limbs, repetitive movements, abnormal postures, and rigidity) or symptoms similar to those of Parkinson's disease. Others have twitching of the face or tongue, or peculiar bulging eyes.
