Genes affected

CA10 (HGNC:1369): (carbonic anhydrase 10) This gene encodes a protein that belongs to the carbonic anhydrase family of zinc metalloenzymes, which catalyze the reversible hydration of carbon dioxide in various biological processes. The protein encoded by this gene is an acatalytic member of the alpha-carbonic anhydrase subgroup, and it is thought to play a role in the central nervous system, especially in brain development. Multiple transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

The c.734A>G (p.Y245C) alteration is located in exon 8 (coding exon 7) of the CA10 gene. This alteration results from a A to G substitution at nucleotide position 734, causing the tyrosine (Y) at amino acid position 245 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
