In our prospective study, hyper-variable regions (CDRI and III) of IgH, TCRD (Vδ2-Dδ3 and Dδ2-Dδ3), TCRG (Vγ, VγI, and VγII), and IgK (Vκ-Kde) were studied in 126 cases with diagnosis of B-precursor ALL.
A large series of 202 childhood precursor-B cell acute lymphoblastic leukemia (ALL) patients was analyzed by Southern blotting (SB) for cross-lineage rearrangements and/or deletions in the T cell receptor TCRB, TCRG and TCRD loci.
We have analysed the structure of the T-cell receptor gamma chain (TCRG) genes in a panel of biopsies taken from 24 patients with acute lymphoblastic leukemia (ALL) (13 cALL, one pre-B ALL, two null ALL and eight T-ALL) at presentation and at clinical relapse.
