 TEL-AML1 fusions are the most common chromosome translocations in childhood leukemia and often, if not always, occur in utero.     ///    "We now report data on sequencing and mapping of TEL-AML1 from an additional 11 patients and, using Monte Carlo statistical methods, have analyzed the intronic distribution of the 24 TEL-AML1 fusion junctions sequenced to date. "    ///    Microclustering of TEL-AML1 translocation breakpoints in childhood acute lymphoblastic leukemia..     ///    We previously reported the genomic sequencing of nine TEL-AML1 translocations and showed unique structural features of a breakpoint cluster region in TEL intron 5.     ///    TEL-AML1 breakpoints may be distributed into microclusters because of specific DNA sequence or chromatin features in susceptible cells.
