Variant | act mut |
Impact List | unknown |
Protein Effect | unknown |
Gene Variant Descriptions | NRAS act mut indicates that the variant results in activation of NRAS downstream signaling. The mechanism causing the activation can include either loss of GTP hydrolysis activity (loss of function) or increased nucleotide exchange rate (gain of function). |

CDKN2A mut NRAS act mut | acute lymphoblastic leukemia | resistant | Trametinib | Preclinical | Actionable | In a preclinical study, human acute lymphoblastic leukemia cells harboring NRAS and CDKN2A mutations were insensitive to Mekinist (trametinib) in culture (PMID: 26343583). | 26343583 |
FGFR3 rearrange NRAS act mut | multiple myeloma | no benefit | Futibatinib | Preclinical - Cell culture | Actionable | In a preclinical study, a multiple myeloma cell line harboring an FGFR3 rearrangement and an NRAS activating mutation was not sensitive to treatment with Lytgobi (futibatinib) in culture (PMID: 32973082). | 32973082 |
