Abstract

We investigated a family with a new type of autosomal dominant cerebellar ataxia (ADCA) in which pure cerebellar ataxia is often accompanied with epilepsy. No CAG repeat expansions were detected at the spinocerebellar ataxia (SCA) type 1, 2, 3, 6, or 7 locus, and SCAs 4 and 5 were excluded by linkage analysis. We found linkage between the disease locus and D22S274 (Zmax = 3.86 at Θ = 0.00) and two other makers in 22q13-qter. Haplotype analysis of the crossover events and the multipoint linkage mapping localized the disease locus to an 8.8-cM region between D22Sl177 and D22S1160.
