| Gene Variant Descriptions | NRAS Q61R is a hotspot mutation that lies within a GTP-binding region of the Nras protein (UniProt.org). Q61R results in increased GTP-bound Nras, which leads to activation of Mapk signaling and cell transformation in culture (PMID: 16818621, PMID: 34117033), and is predicted to lead to a loss of GTPase activity based on the effect of HRAS Q61R (PMID: 3510078). |
