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]

The c.119C>T (p.P40L) alteration is located in exon 3 (coding exon 2) of the ATCAY gene. This alteration results from a C to T substitution at nucleotide position 119, causing the proline (P) at amino acid position 40 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
