We report our observations in an Australian family with spinocerebellar ataxia type 14 (SCA 14). We describe a novel mutation in exon 5 of the PRKCG gene, altering a highly conserved cysteine to a phenylalanine at codon 150, and record the detailed clinical observations in six affected family members.

  • ADCA, autosomal dominant cerebellar ataxia
  • PRKCG gene, protein kinase C gamma gene
  • SCA, spinocerebellar ataxia
  • VOR, vestibulo-ocular reflex
  • SCA 14
  • spinocerebellar ataxia
