FLT3 and acute myeloid leukemia: This is consistent with research by Wells et al., (1996) where CD117 was present in 87% of cases of AML, and with the results of a cohort study by Sharawat et al., (2013), where CD135 and CD117 expressions >20% were observed in 82% and 90% of patients’ myeloblasts.Tarlock et al., (2017) reported that there was no significant associa-tion between CD135 expression and the WBC count.
