METHODS FOR SCREENING AND TREATING LEUKEMIAS RESULTING FROM ALL-1 REGION CHROMOSOME ABNORMALITIES

摘要

Methods are provided for the diagnosis and treatment of human leukemias involving breakpoints on chromosome 11 in the ALL-1 locus. The ALL-1 breakpoint region, an approximately 8 kb region on chromosome 11, is also disclosed. The ALL-1 region is involved in translocations in acute lymphocytic, myelomonocytic, monocytic and myelogenous leukemias. Probes which identify chromosome aberrations involving the ALL-1 breakpoint region on chromosome 11 are also provided. cDNA sequences of the ALL-1 gene on chromosome 11, the AF-9 gene on chromosome 9, the AF-4 gene on chromosome 4, the AF-6 gene on chromosome 6 and the AF-17 gene on chromosome 17 and corresponding amino acid sequences are also provided. Probes are provided for detecting chromosome abnormalities involving these genes. Chimeric genes involved in translocations are disclosed. Monoclonal antibodies for diagnosis and treatment and antisense oligonucleotides for treatment of acute leukemias are also described.
