FLT3 | N701K | missense | gain of function - predicted | FLT3 N701K lies within the protein kinase domain of the Flt3 protein (UniProt.org). N701K results in transformation activity and has been associated with resistance to some FLT3 inhibitors in the context of FLT3-ITD in cultured cells (PMID: 33780043), and therefore, is predicted to lead to a gain of Flt3 protein function. | Y |
