| Identified Mutation |
(CAG)n EXPANSION; The cause of spinal cerebellar ataxia 1 (SCA1; 164400) is an expansion of a (CAG)n repeat in the gene encoding ataxin-1 located on 6p (Orr et al., 1993; Banfi et al., 1994). Most unexpanded alleles have an interrupted repeat configuration, whereas a contiguous repeat (CAG)n is found in expanded alleles. The repeat instability in SCA1 is probably more complex than a simple variation in repeat number; the loss of an interruption predisposes the SCA1 (CAG)n repeat to expansion.

| Remarks |
Ataxia; dysarthria; amyotrophy; dysphagia; analysis of ATXN1 (ATX1) alleles showed normal allele with 32 CAG repeats and expanded allele with 60 repeats |
