Genes affected
ATCAY (HGNC:779): (ATCAY kinesin light chain interacting caytaxin) This gene encodes a neuron-restricted protein that contains a CRAL-TRIO motif common to proteins that bind small lipophilic molecules. Mutations in this gene are associated with cerebellar ataxia, Cayman type. [provided by RefSeq, Jul 2008]
