Genes affected

CACNG5 (HGNC:1409): (calcium voltage-gated channel auxiliary subunit gamma 5) The protein encoded by this gene is a type II transmembrane AMPA receptor regulatory protein (TARP). TARPs regulate both trafficking and channel gating of the AMPA receptors. This gene is part of a functionally diverse eight-member protein subfamily of the PMP-22/EMP/MP20 family and is located in a cluster with two family members, a type I TARP and a calcium channel gamma subunit. This gene is a susceptibility locus for schizophrenia and bipolar disorder. [provided by RefSeq, Dec 2010]

The c.808A>G (p.M270V) alteration is located in exon 5 (coding exon 5) of the CACNG5 gene. This alteration results from a A to G substitution at nucleotide position 808, causing the methionine (M) at amino acid position 270 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
