Gene NRAS
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).
Associated Drug Resistance

NRAS mutant NRAS act mut

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

NRAS act mut lung non-small cell carcinoma predicted - resistant Osimertinib Case Reports/Case Series Actionable In a retrospective analysis, activating NRAS mutations were identified in 1 of 100 patients with non-small cell lung cancer at treatment discontinuation of Tagrisso (osimertinib) (PMID: 31839416). 31839416
NRAS act mut Advanced Solid Tumor no benefit Selumetinib Clinical Study - Cohort Actionable In a Phase II trial (MATCH), Koselugo (selumetinib) treatment resulted in a 15% (3/20) six-month progression-free survival rate, no objective responses, and did not lead to tumor regression in pediatric patients with advanced solid tumors including high grade glioma (n=8) and rhabdomyosarcoma (n=7) that harbored MAPK pathway alterations including activating NRAS, HRAS, or KRAS mutations, BRAF V600E, or inactivating NF1 mutations (J Clin Oncol 39, no. 15_suppl (May 20, 2021) 10008; NCT03213691, NCT03155620). detail...
NRAS act mut melanoma predicted - sensitive Binimetinib + Ribociclib Phase Ib/II Actionable In a Phase Ib/II trial, Kisqali (ribociclib) plus Mektovi (binimetinib) was well tolerated in NRAS-mutant melanoma patients and resulted in an overall response rate of 19.5% (8/41; all PR), disease control rate of 70.7% (29/41), median duration of response of 10.3mo, median progression-free survival of 3.7mo, and median overall survival of 11.3mo in phase II, and a response rate of 22.9% (16/70) in patients with an NRAS Q61 mutation, and 12.5% (1/8) with NRAS G12/G13 mutation (PMID: 35294522; NCT01781572). 35294522
NRAS act mut melanoma predicted - sensitive Binimetinib + KIN-2787 Preclinical - Cell line xenograft Actionable In a preclinical study, KIN-2787 and Mektovi (binimetinib) combination treatment inhibited growth of melanoma cell lines harboring NRAS mutations in culture, and resulted in improved tumor growth inhibition and Mapk pathway suppression in cell line xenograft models compared to either agent alone (J Clin Oncol 40, 2022 (suppl 16; abstr e15099)). detail...
NRAS act mut melanoma predicted - sensitive FCN-159 Phase I Actionable In a Phase I trial (FCN-159-001), FCN-159 treatment was well tolerated in melanoma patients harboring NRAS activating mutations and resulted in an objective response rate (ORR) of 19% (4/21, all partial responses), a clinical benefit rate (CBR) of 52.4% (11/21), and a median progression-free survival (mPFS) of 3.8 mo across all doses tested, and a CBR of 50% (3/6), mPFS of 3.8 mo at the RP2D dose of 12mg (PMID: 36113242; NCT03932253). 36113242
NRAS act mut multiple myeloma predicted - sensitive BMF-219 Preclinical - Cell culture Actionable In a preclinical study, BMF-219 inhibited growth of multiple myeloma cell lines harboring NRAS activating mutations in culture (Cancer Res 2022;82(12_Suppl):Abstract nr 2654). detail...
