FISH

Myeloma FISH Panel

Methodology: FISH

Clinical Significance:
Several recurrent and prognostic chromosome alterations have been identified in myeloma and their identification is useful in the management of these patients. These include translocations involving the FGFR3, MAF, MAFB and CCND1 genes with the IGH gene, loss of 17p13.1(P53), loss of 13q14.3, rearrangement of MYC, and hyperdiploidy. The t(14;16), t(4;14), and t(14;20) translocations involving the MAF, FGFR3, and MAFB genes, respectively, each independently identify poor prognostic groups. Deletion of 13q14.3, rearrangement of MYC, or 17p13.1(P53) are two additional poor prognostic indicators in myeloma. Hyperdiploidy is associated with a favorable prognosis and the t(11;14) portends an intermediate prognosis.
