  • Title: Locus of the alpha-chain of the T-cell receptor is split by chromosome translocation in T-cell leukemias.
    Author: Erikson J, Williams DL, Finan J, Nowell PC, Croce CM.
    Journal: Science; 1985 Aug 23; 229(4715):784-6. PubMed ID: 3875152.
    Abstract:
    Mouse lymphoma cells were hybridized with two human acute T-cell leukemias with a t(11;14) (p13;q11) translocation and the segregated hybrids were examined for the presence of the DNA segments coding for the constant (C) and the variable (V) regions of the alpha chain (C alpha and V alpha) of the T-cell receptor. The C alpha segment was translocated to the involved chromosome 11 (11p+) while the V alpha segment remained on the involved chromosome 14 (14q-). The data indicate that the locus for the alpha chain of the T-cell receptor is split by the chromosomal breakpoint between the V alpha and the C alpha gene segments, and that the V alpha segments are proximal to the C alpha segment within chromosome band 14q11.2.
