| A very rare progressive and untreatable disease with manifestations of ataxia with sensory neuropathy. Prevalence is unknown, typically starts in middle-aged adults and presents with cerebellar ataxia, pyramidal signs, and peripheral sensory loss. The disease has been linked to chromosome 16q22.1 in kindreds from Utah (USA) and Germany but the mutation is yet unknown and does not appear to involve trinucleotide repeats. |
