Abstract From the Canadian patent

The sequence of the protein coding regions of the bc1-2 gene are provided as well as bacterial clones which produce the proteins. Assays are provided for detecting a class of B-cell neoplasms associated with a chromosome translocation between chromosomes 14 and 18. This translocation is involved in the majority of cases of human follicular lymphomas. One assay employs an antibody which is immunoreactive with a human protein which is over-expressed due to the chromosome translocation. Another assay involves measurement of the amount of mRNA which hybridizes to the gene proximal to this translocation break-point.
