High prevalence of a form of autosomal recessive spastic ataxia with early onset was originally described among French Canadians in the Charlevoix-Saguenay region, in northeastern Quebec. Since the responsible gene (SACS) was identified, mutations in the SACS gene have been described in Tunisia, Italy, Turkey, and Japan. The mutation sites found outside Quebec are different from the ones in Quebec. All patients outside Quebec, except one Italian patient, have been reported to have homozygous mutations. The authors report here identical twin sisters with novel compound heterozygous mutations (c.[2951_2952delAG]+[3922delT]) in the SACS gene.
