Please see PML::RARA MRD monitoring for follow up samples.

The PML::RARA rearrangement is present approximately in 98% of acute promyelocytic leukaemia (APL) cases and defines a diagnosis of APL regardless of blast percentage. APL is considered to have a favourable prognosis when treated with all-trans-retinoic acid in combination with arsenic trioxide.

PML-RARA fusion gene analysis is carried out as part of the AML testing panel, which also includes CBFB::MYH11, BCR::ABL1, RUNX1::RUNX1T1, KMT2A fusion gene, FLT3 (ITD and D835 point mutation) and NPM1 gene mutation analysis.
