TRAJ7 and Sezary syndrome: Based on our recent finding of a novel chromosomal translocation t(14;14)(q11;q32) that was involved in a gene rearrangement from TRAJ7 to PPP2R5C in a patient with Sézary syndrome (data unpublished), in the present study, we further characterized the expression and distribution of five different transcript variants of the PPP2R5C gene in leukemia.
