''FLT3'' mutations occur in about one-third of patients with AML [3]. In-frame duplications of 3 to >400 base pairs, also known as internal tandem duplications (ITDs), are the most common mutations in ''FLT3'' and they occur in up to 30% of adult patients with ''de novo'' AML [3,4,5,6]. About 70% of ''FLT3''-ITDs occur in the JMD and about 30% in the TKD [3]. The JMD inhibits activation of the receptor by steric hindrance, preventing the TKD from assuming an active conformation; presence of an ITD causes loss of this inhibitory effect, resulting in activation of the TKD.
