Summation

Translocations which put the FGFR3 gene under the control of the strong IGH promoter have been identified in 15% of multiple myelomas (Avet-Loiseau, 1998; Chesi, 1997; Chesi, 2001). This translocation, which occurs 70kb upstream of the FGFR3 gene, also involves the nearby multiple myeloma SET-domain containing (MMSET) gene (Lauring, 2008), and although the contribution of each of these genes to the development of cancer has not been fully elucidated, several studies have shown that t(4:14) myeloma cell lines are sensitive to FGFR3 inhibitors (Trudel, 2006; Qing, 2009). In ~5% of cases, the translocation is accompanied by activating mutations of FGFR3 (Onwuazor, 2003; Ronchetti, 2001). The t(4;14) translocation results in overexpression of FGFR3 and subsequent ligand independent or anomalous ligand-dependent signaling (Otsuki, 1999).
