KIT, also known as proto-oncogene c-Kit or tyrosine-protein kinase Kit or CD117, is a growth factor receptor of the tyrosine kinase subclass III family, normally expressed in a variety of tissue types. Signaling through CD117 plays a role in cell survival, proliferation, and differentiation. Altered forms of this receptor may be associated with many types of cancers including hematopoietic malignancies, gastrointestinal stromal tumors, and various carcinomas and sarcomas. KIT G565V lies within the cytoplasmic domain of the Kit protein; this variant has been documented in the scientific literature (in melanoma). While its effect on Kit protein function is unknown, it is reported in ClinVar as likely benign germline variant (https://preview.ncbi.nlm.nih.gov/clinvar/variation/41600/).
