RARα (RARA) Breakapart

Catalogue Numbers
LPH 065 (10 tests)
LPH 065-S (5 tests)

Acute Promyelocytic Leukaemia (APL) is associated with chromosomal rearrangements involving the retinoic acid receptor α (RARA) gene, on chromosome 17q21.1-q21.2, and various partner genes situated on different chromosomes2.

In the vast majority of APL cases, the RARA gene fuses with the Promyelocytic Leukaemia (PML) gene located on chromosome 15q24, as a result of a t(15;17) translocation, but RARA fusions with Promyelocytic Leukemia Zinc Finger (PLZF (now known as ZBTB16), 11q23.2), Nucleophosmin (NPM1, 5q35.1), Nuclear Mitotic Apparatus protein 1 (NUMA1, 11q13.4), Myeloid/lymphoid or Mixed Lineage Leukaemia (MLL (KMT2A), 11q23.3) and FIP1-like-1 (FIP1L1, 4q12) genes have also been described1,2,3. The RARAα (RARA) Breakapart probe will detect rearrangements of the RARA gene, irrespective of partner genes or chromosomes involved.
