Molecular variant of the NPM-ALK rearrangement of Ki-1 lymphoma involving a cryptic ALK splice site..     ///    "In the course of a survey of 15 cases of Ki-1 ALCL, we identified a single case with a slightly smaller NPM-ALK RT-PCR product, among 12 cases positive for this fusion RNA. "    ///    "Sequencing of this novel NPM-ALK RT-PCR product showed an in-frame junction of NPM to ALK, 30 bases distal to the usual ALK junction site, but at the usual NPM Junction site. "
