| Gene Variant Descriptions | RET L881V lies within the protein kinase domain of the Ret protein (UniProt.org). L881V has been demonstrated to confer resistance to some RET inhibitors in the context of KIF5B-RET in cultured cells (PMID: 31118272), but has not been biochemically characterized and therefore, its effect on Ret protein function is unknown (PubMed, Aug 2025). |
