Gene Variant Descriptions | FLT3 D835X indicates any Flt3 missense mutation that results in the replacement of the aspartic acid (D) at amino acid 835 by a different amino acid. FLT3 codon 835 mutations are hotspot mutations that often result in constitutive phosphorylation of Flt3 and activation of downstream signaling (PMID: 11290608, PMID: 15256420). |
