Gene HRAS
Variant act mut
Impact List unknown
Protein Effect unknown
Gene Variant Descriptions HRAS act mut indicates that the variant results in activation of HRAS 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

HRAS mutant HRAS 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.

HRAS act mut transitional cell carcinoma predicted - sensitive Tipifarnib Phase II Actionable In a Phase II trial, Zarnestra (tipifarnib) demonstrated safety and preliminary efficacy in patients with metastatic urothelial carcinoma harboring HRAS mutations (n=14) or STK11:rs2075606, 3 of 4 patients achieved progression-free survival at 6 months harbored HRAS activating mutations, and no response was observed in HRAS wild-type patients (J Clin Oncol 38: 2020 (suppl; abstr 5086); NCT02535650). detail...
HRAS act mut salivary gland carcinoma sensitive Tipifarnib Clinical Study Actionable In a clinical study, Zarnestra (tipifarnib) treatment resulted in an overall response rate of 8% (n=13) with one ongoing partial response with a duration of 14 months and stable disease as the best response in 58% (7/12) of evaluable patients with HRAS-mutant metastatic salivary gland carcinoma, and a median overall survival of 18 months, and a median progression-free survival of 7 months (PMID: 32557577). 32557577
HRAS 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 HRAS, KRAS, or NRAS mutations, BRAF V600E, or inactivating NF1 mutations (J Clin Oncol 39, no. 15_suppl (May 20, 2021) 10008; NCT03213691, NCT03155620). detail...
