摘要: The Philadelphia (Ph) chromosome, the product of t(9:22), is cytogenetic hallmark chronic myelogenous leukemia. c-abl oncogene on chromosome 9 translocated to Ph and linked a breakpoint cluster region (bcr), which part large bcr gene. This results in formation bcr-c-abl fusion gene, transcribed into an 8.5 kb chimeric mRNA encoding 210 kd protein. also found acute lymphoblastic leukemia (Ph+ ALL). Although new 190 protein has been identified, no breakpoints are observed (Ph+bcr- Here we show that Ph+bcr- ALL, 22 occur within same but more 5' bcr. Cloning cDNA demonstrates gene 7 mRNA, novel
