Complex variant translocation t(1;2) with TPM3-ALK fusion due to cryptic ALK gene rearrangement in anaplastic large-cell lymphoma.

To the Editor: Anaplastic large-cell lymphoma (ALCL) is frequently associated with the recurrent translocation t(2;5)(p23;q35) that results in activation of the anaplastic lymphoma kinase ( ALK ) gene at 2p23 by fusion to the ubiquitously expressed gene encoding the nucleolar phosphoprotein
