Flt3 internal tandem duplication (ITD).
2A. The structure of normal Flt3. The ITD occurs in the juxta-membrane region (JM).
2B. A Cartoon of the FLT3/ITD. A 20-200 bp region from exon 11-12 (blue box) is duplicated and inserted in a head-to-tail fashion.
2C. PCR of AML samples. Amplification of wild type Flt3 yields a 320 bp PCR amplimer. The higher bands in sample 11, 12, and 14 are Flt3/ITDs.
