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.277A>C (p.I93L) alteration is located in exon 1 (coding exon 1) of the GNA13 gene. This alteration results from a A to C substitution at nucleotide position 277, causing the isoleucine (I) at amino acid position 93 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
