Gene Variant Descriptions | FLT3 D835V lies within the protein kinase domain activation loop of the Flt3 protein (PMID: 11290608). D835V results in constitutive phosphorylation of Flt3 and activation of Stat5, Erk signaling, leading to transformation of cultured cells (PMID: 15256420), and has been demonstrated to promote secondary drug resistance in the context of FLT3 internal tandem duplication (FLT3-ITD) mutations (PMID: 22504184, PMID: 29187377). |
