|Gene Variant Descriptions||HRAS R135A does not lie within any known functional domains of the Hras protein (UniProt.org). R135A results in impaired GTP-HRAS downstream signaling when combined with R128A (PMID: 18273062), and is associated with resistance to NS1 (PMID: 27820802), but has not been fully biochemically characterized and therefore, its effect on Hras protein function is unknown.|

|HRAS G12V HRAS R135A||Advanced Solid Tumor||resistant||NS1||Preclinical||Actionable||In a preclinical study, introducing HRAS R135A mutation in transformed cells expressing HRAS G12V resulted in reduced binding of Hras to NS1, leading to resistance to Mapk pathway inhibition in cell culture (PMID: 27820802).||27820802|
