| Gene Variant Descriptions | NRAS G12A is hotspot mutation that lies within a GTP-binding region of the Nras protein (UniProt.org). G12A results in increased Erk1/2 and Stat5 phosphorylation and transformation in culture (PMID: 35211470), and can be predicted to confer a loss of function to the Nras protein based on the effects of HRAS G12A and KRAS G12A, which results in decreased GTPase activity, loss of response to GTPase-activating proteins, and transformation of cultured cells (PMID: 6092966, PMID: 26037647). |
