| Gene Variant Descriptions | NRAS G12S is a hotspot mutation that lies within a GTP-binding region of the Nras protein (UniProt.org). G12S results in increased Erk phosphorylation and cell proliferation (PMID: 17823240), increased Stat5 phosphorylation in culture (PMID: 35211470), is transforming in one study (PMID: 17823240), but is not transforming in another study (PMID: 35211470), and therefore, its effect on Nras protein function is unknown. |
