title: The chromosome 11 region flanking the t(11;14) breakpoint in human T-ALL is deleted in Wilms' tumor hybrids.
abstract: Human chromosomal band 11p13 has been implicated in T cell malignancies carrying t(11;14)(p13;q11) reciprocal translocations and has also been associated with Wilms' tumor and aniridia in a mechanism characterized by overlapping hemizygous constitutional deletions spanning this region. Using probes derived from the T cell receptor delta gene, we have cloned the chromosomal breakpoint in an acute T cell leukemia (T-ALL). Southern blotting analyses of mouse-human somatic cell hybrids from this human T-ALL sample and Chinese hamster-human somatic cell hybrids derived from Wilms' tumor lines have indicated that the 11p13 locus, tcl-2, juxtaposed to the TCR (T cell receptor) delta locus in T cell leukemia, is within the constitutional deletion of two Wilms' tumor-aniridia cases.
