FISH FOR T(1;19) OR TCF3/PBX1

Description

FISH (Fluorescence In Situ Hybridization) is a molecular cytogenetic technique used to detect specific chromosomal abnormalities, including the t(1;19) translocation, which results in the TCF3-PBX1 gene fusion. This translocation is frequently observed in B-cell acute lymphoblastic leukemia (B-ALL).
