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.97G>A (p.G33R) alteration is located in exon 3 (coding exon 2) of the ATCAY gene. This alteration results from a G to A substitution at nucleotide position 97, causing the glycine (G) at amino acid position 33 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
