Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_006572.6(GNA13):​c.1126C>G​(p.Leu376Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as other (no stars).

• Frequency: Genomes: not found (cov: 32)
• Consequence: GNA13 NM_006572.6 missense
• Clinical Significance: - - O:1
• Conservation: PhyloP100: 3.18

Genes affected

GNA13 (HGNC:4381): (G protein subunit alpha 13) Predicted to enable D5 dopamine receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Predicted to be involved in several processes, including Rho protein signal transduction; activation of phospholipase D activity; and multicellular organism aging. Predicted to act upstream of or within several processes, including branching involved in blood vessel morphogenesis; negative regulation of vascular associated smooth muscle cell migration; and negative regulation of vascular associated smooth muscle cell proliferation. Located in cytosol and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
