Laboratory assay overview
FISH testing with the TCF3-PBX1 dual fusion dual color probe allows detection of balanced and unbalanced translocations involving 1q23.3 (PBX1) and 19p13.3 (TCF3). This translocation has been observed in acute lymphoblastic leukemia with a precursor-B immunophenotype. Furthermore, a variant translocation, involving 17q22 (HLF) and 19p13.3 (TCF3) can be detected with this probe.
