Detects the MLL partial tandem duplication (PTD) between exons 2 and 8 in the MLL gene.
disease state indication(s)
Acute myeloid leukemia (AML)
MLL partial tandem duplication (PTD) is found in approximately 5-11% of cytogenetically normal acute myeloid leukemia (AML) and up to 90% of AML with trisomy 11. In patients with AML, MLL-PTD is an adverse prognostic indicator for overall survival [1-2].
