Paediatric Acute Leukaemia Translocations (Accredited)


The WHO classification of haematopoietic tumours uses genetic markers to aid in the classification of Precursor Lymphoid Neoplasms. The identification of the t(12;21) (TEL::AML1 or ETV6::RUNX1), t(4;11) (KMT2A::AFF1 or MLL::AF4) and t(1;19) (E2A::PBX1 or TCF3::PBX1) are useful diagnostic tools and also have prognostic significance that allow for therapeutic stratification.


In this programme participants are provided with lyophilised cell-lines for t(12;21) (TEL::AML1 or ETV6::RUNX1), t(4;11) (KMT2A::AFF1 or MLL::AF4) and t(1;19) (E2A::PBX1 or TCF3::PBX1) analysis. Participants are asked to submit qualitative results, together with details of the methodology. All samples mimic diagnostic specimens and are therefore not suitable for MRD analysis; this may be subject to change dependent on participants’ feedback. Instructions for storage, reconstitution and use of the lyophilised samples are included with the samples. Three send-outs are issued per annum, with each send-out consisting of two samples.


Trials for this programme are live/open for a minimum of 4 weeks.

Please Note: Trials issued/closing in August or December are extended by 1 week.

An automated email is sent 2 days prior to the trial closing, to any participant that has not returned results, warning them of the trial closure date. 


Fusion Gene Nomenclature - Latest Update 

Following the recent publication of the HUGO Gene Nomenclature committee (HGNC) consensus statement regarding fusion gene nomenclature (Bruford et al. 2021), UK NEQAS LI are working to implement use of the double colon (::) for the description of fusion genes (e.g. BCR::ABL1). Historical nomenclature (e.g. BCR-ABL1) may persist in some areas of our website and documentation for an interim period due to IT constraints.

Pre-issue and post-closure testing of samples for this programme is subcontracted, although the final decision about sample suitability lies with the EQA provider; no other activities in relation to this EQA programme are subcontracted.
