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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.152T>C (p.L51P) alteration is located in exon 4 (coding exon 3) of the ATCAY gene. This alteration results from a T to C substitution at nucleotide position 152, causing the leucine (L) at amino acid position 51 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
