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]

The c.950A>G (p.H317R) alteration is located in exon 4 (coding exon 4) of the GNA13 gene. This alteration results from a A to G substitution at nucleotide position 950, causing the histidine (H) at amino acid position 317 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
