| Gene Variant Descriptions | RET Y791F lies within the protein kinase domain of the Ret protein (UniProt.org). Y791F results in ligand-independent kinase activity and activation of Stat3 signaling and is transforming in cell culture (PMID: 17209045, PMID: 15753368), but does not respond to growth factor stimulation in culture (PMID: 17209045) and results in enteric nervous system development similar to wild-type in a transgenic mouse model (PMID: 32275061), and therefore, its effect on Ret protein function is unknown. |
