摘要:: The simultaneous occurrence of two different translocations affecting both alleles of the IGH gene has rarely been reported in multiple myeloma. In such a case, two different oncogenes might become transcriptionally deregulated. To investigate this hypothesis, we have characterized the plasma cell leukemia cell line SK-MM2 and a primary myeloma both carrying simultaneous IGH-FGFR3/MMSET and IGH-CCND1 fusions as shown by multicolor fluorescence in situ hybridization. Remarkably, quantitative real-time polymerase chain reaction demonstrated that only one of the oncogene loci was transcriptionally upregulated in both instances. Moreover, the upregulated oncogenes differed between both samples. Thus, biallelic IGH translocations might exert different pathogenetic effects in plasma cell disorders.
