FLT3 mutations are among the most common mutations in AML and occur as either in-frame duplications within the juxtamembrane region (FLT3-ITD, internal tandem duplication) or as point mutations within the tyrosine kinase domain (FLT3-TKD) at a frequency of around 25% and 7% of AML cases, respectively [1]. Here, FLT3 is linked to acute myeloid leukemia.
