| 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). |
