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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.650A>G (p.Y217C) 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 650, causing the tyrosine (Y) at amino acid position 217 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
