The ENST00000715275.1(GNA12):n.60+17454G>T variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: ENST00000715275.1 is not a MANE Select or MANE Plus Clinical transcript for GNA12; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The gene GNA12 is a known oncogene (CancerMine: 1 oncogene citations). The variant allele was found at a cumulative frequency of 0.236 (AC=35,807) in the gnomAD database across 152,032 control chromosomes, including 4,974 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.322. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

GNA12 (HGNC:4380): (G protein subunit alpha 12) Enables G protein activity; protein phosphatase 2A binding activity; and protein phosphatase activator activity. Involved in Rho-activating G protein-coupled receptor signaling pathway; regulation of TOR signaling; and regulation of proteasomal ubiquitin-dependent protein catabolic process. Located in several cellular components, including cytosol; lateral plasma membrane; and neuronal cell body. [provided by Alliance of Genome Resources, Jun 2026]
