Gene HRAS
Variant A146T
Impact List missense
Protein Effect gain of function
Gene Variant Descriptions HRAS A146T lies within the SAK motif of the Hras protein (PMID: 24224811). A146T does not affect Hras intrinsic GTPase activity, but results in increased nucleotide exchange rates, which leads to increase GTP-bound Hras, activation of downstream signaling, and senescence of cultured cells (PMID: 24224811, PMID: 21850009).

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. 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 on a longer phrase with spaces (i.e. "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 A146T head and neck squamous cell carcinoma predicted - sensitive Tipifarnib Preclinical - Pdx Actionable In a preclinical study, a head and neck squamous cell carcinoma patient-derived xenograft (PDX) model harboring HRAS A146T was sensitive to treatment with Zarnestra (tipifarnib), demonstrating inhibition of tumor growth, decreased cell proliferation, and reduced Erk activity (PMID: 32727882). 32727882
