Spinocerebellar ataxia (SCA) types 13 and 25 are two genetic entities among the
autosomal dominant cerebellar ataxias, initially mapped in two French families to
chromosomes 19q and 2p, respectively. The SCA13 locus was confirmed by the
identification of a second kindred of Filipino ancestry. SCA13 patients have
cerebellar ataxia of adult onset, or of early onset when associated with mental
impairment. SCA25 patients present with cerebellar ataxia with sensory neuropathy
and frequent gastrointestinal features. While the gene responsible for SCA25 is
still unknown, missense mutations affecting the potassium channel KCNC3 function
have been identified.
