A phenotype without spasticity in sacsin-related ataxia
Abstract
The authors describe two Japanese siblings with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) without spasticity, usually a core feature of this disorder. They had a novel homozygous missense mutation (T987C) of the SACS gene, which resulted in a phenylalanine-to-serine substitution at amino acid residue 304.
