| Gene Variant Descriptions | RET G691S lies within the cytoplasmic domain of the Ret protein (UniProt.org). G691S is a common polymorphism (PMID: 39671698, PMID: 26191299) that results in increased Ret phosphorylation and activation of downstream signaling pathways in response to Gdnf, and increased invasion in cultured cells (PMID: 16357163, PMID: 19561646), but in another study results in focus formation and proliferation similar to wild-type RET in cultured cells (PMID: 21810974), and therefore, its effect on Ret protein function is unknown. |
