| Gene Variant Descriptions | KIT A502_Y503dup (also referred to as Y503_F504insAY) indicates the insertion of 2 duplicate amino acids, alanine (A)-502 through tyrosine (Y)-503, in the Ig-like C2-type domain 5 (exon 9) of the Kit protein (UniProt.org). A502_Y503dup results in constitutive phosphorylation of Kit and is transforming in cell culture (PMID: 15790786, PMID: 19865100). |
