摘要：
We identified two patients with atypical PML-RARalpha rearrangements, 53 and 13 base pairs longer than the typical bcrl transcript. Sequence analysis revealed a new PML breakpoint at the end of exon 7a in patient 1, and a PML exon 6 breakpoint in patient 2, with an insertion of 35 nucleotides of RARalpha intron 2. Patient I did not express RARalpha,-PML and patient 2 showed the RARalpha-PML transcript, which corresponded to the typical bcrl. These results emphasize on the relevance of the correct identification of atypical PML-RARalpha rearrangements because of the potential implications in leukemogenesis, in the response to treatment, and for the correct monitoring of minimal residual disease.
