B lymphoblastic leukaemia/lymphoma (B-ALL) with t(17;19)(q22;p13), resulting in the TCF3::HLF gene fusion, is newly recognized as a distinct entity in the WHO 5th edition classification. TCF3 rearrangements are identified in approximately 5–11% of B-ALL cases, with several fusion partners reported, including PBX1, HLF, and ZNF384. B-ALL with TCF3::PBX1 fusion is also classified as a separate entity in the latest WHO edition<ref>WHO Classification of Tumours Editorial Board, eds, WHO Classification of Tumours, Haematolymphoid Tumours, 5th edition, IARC Press:Lyon, 2024. Online at WHO Classification of Tumours</ref>.

''DUX4'' has many homologous genes; an alternate translocation in a minority of cases is t(10;19), but this is usually indistinguishable from t(4;19) by short-read sequencing (add references).

The most common ''ALK'' fusion is ''EML4::ALK'', with breakpoints in intron 19 of ''ALK''. At the transcript level, a variable (5’) partner gene is fused to 3’ ''ALK'' at exon 20. Rarely, ''ALK'' fusions contain exon 19 due to breakpoints in intron 18.

* This ALL subtype is classified based on the presence of a t(17;19)(q22;p13), which results in fusion of the 5’ portion of ''TCF3'' at “19p13” and the 3’ portion of ''HLF'' at “17q22”.
