Spinocerebellar Ataxia Type 4

SCA4

Clinical description SCA4 typically starts in middle-aged adults and presents with cerebellar ataxia, pyramidal signs, and peripheral sensory loss. [orpha.net]

In the present study, the first available cerebellar and brainstem tissue of a clinically diagnosed and genetically-confirmed German SCA4 patient was pathoanatomically studied using serial thick sections. [ncbi.nlm.nih.gov]

As the disease progresses, abnormal movements become more pronounced and can present problems in gait, speech or swallowing. Survival from the onset of symptoms, may be a few years to over a decade. [ivami.com]

Prognosis There is insufficient clinical data to draw conclusions concerning prognosis. [orpha.net]

Prognosis Spinocerebellar ataxias due to repeat expansion mutations usually become sick in middle age. In addition to ataxia, other neurological findings are often present depending on the variant of SCA. [verywell.com]

Prognosis Prognosis is highly variable between the different types but improvement is unlikely. [patient.info]

The prognosis is bleak, with a gradual progression to disability and death within 10-20 years. Ref: Orr, H.T. et al. (1993). Expansion of an unstable CAG trinucleotide repeat in spinocerebellar ataxia type I. Nature Genet. 4, 221-26. [gpnotebook.co.uk]

Prognosis The prognosis for a person with ataxia depends upon the type and nature of the disease. Ataxia as a result of trauma or infection may be a temporary condition, or leave some degree of permanent disability. [encyclopedia.com]

Etiology The disease has been linked to chromosome 16q22.1 in kindreds from Utah (USA) and Germany but the mutation is yet unknown and does not appear to involve trinucleotide repeats. [orpha.net]

Its etiology is mostly caused by mutations characterized by the presence of an expansive and unstable CAG trinucleotide repeat in the coding region of the tested gene. [tinnitusjournal.com]

Moreover, increased intracellular Ca 2 , which promotes transglutaminase activation, is of vital importance in the etiology of neurologic diseases. [emedicine.medscape.com]
