General additional information

ETV6::RUNX1 fusion gene testing is performed on all patients <70 years old diagnosed with ALL based on immunophenotyping results via a reflex testing strategy. 

Please see ETV6::RUNX1 MRD monitoring for follow up samples.

The ETV6::RUNX1 fusion oncogene arises as a result of the t(12;21)(p13;q22) cryptic translocation. It is observed in approximately 25% of paediatric B-ALL and is associated with a more favourable prognosis.

ETV6::RUNX1 fusion gene analysis is carried out as part of the Acute Lymphoblastic Leukaemia testing panel, which also includes BCR::ABL1, TCF3::PBX1 and KMT2A fusion gene analysis.
