To the Editor:

Multiple myeloma (MM) is a hematologic neoplasm characterized by a clonal expansion of malignant plasma cells (PCs) in the bone marrow, showing clinical, genetic, and epigenetic heterogeneity. Chromosomal translocations are one of the hallmarks of MM, and mainly involve the immunoglobulin heavy chain locus (IGH). These translocations usually result in the placement of various oncogenes under the control of IGH, leading to the up-regulation of genes that provide a selective growth advantage to MM cells.1 Five recurrent IGH translocations have been described in MM; however, in many cases, the second gene involved is not defined in routine clinical analyses. Besides, recent studies have reported novel recurrent fusion partners and novel non-IGH fusions beyond well-known translocations.2, 3 Nevertheless, these approaches did not consider the normal counterpart of B-cells, which may provide new insights regarding the role of fusion transcripts (FT) in MM. Furthermore, MM is also associated with deregulation of long noncoding RNAs (lncRNA), a group of genes with increasing relevance in cancer.4 Various studies suggest the involvement of lncRNAs in chromosomal translocations; however, this has not been assessed in MM.
