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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 21, 2023The c.361G>A (p.G121R) alteration is located in exon 3 (coding exon 3) of the CACNG5 gene. This alteration results from a G to A substitution at nucleotide position 361, causing the glycine (G) at amino acid position 121 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
