Mutation detailsPhenylalanine codon 227 (TTT) in exon 2 was deleted (p.F227del). The mutation, in the second transmembrane domain of the encoded protein, is the equivalent of the same human mutation associated with spinocerebellar ataxia type 22 (SCA22). It causes degeneration of several cellular compartments and trafficking defects, which affects neural electrophysiology and leads to motor coordination and balance deficits. (J:363793)
