The known FLT3 gene mutation rate in adult AML patients is 20%-25% [22,25]; however, Liang et al. [24] reported a mutation rate in childhood AML patients of 11.3%, and Kondo et al. [22], Iwai et al. [25], and Krstovski et al. (26) reported rates of 5.3%-16.5%. This evidence concerns the gene FLT3 and acute myeloid leukemia.
