Genes affected

SLC24A2 (HGNC:10976): (solute carrier family 24 member 2) This gene encodes a member of the calcium/cation antiporter superfamily of transport proteins. The encoded protein belongs to the SLC24 branch of exchangers, which can mediate the extrusion of one Ca2+ ion and one K+ ion in exchange for four Na+ ions. This family member is a retinal cone/brain exchanger that can mediate a light-induced decrease in free Ca2+ concentration. This protein may also play a neuroprotective role during ischemic brain injury. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

The c.595G>A (p.A199T) alteration is located in exon 1 (coding exon 1) of the SLC24A2 gene. This alteration results from a G to A substitution at nucleotide position 595, causing the alanine (A) at amino acid position 199 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
