Abstract

We constructed a multiple myeloma (MM)-specific gene panel for targeted sequencing and investigated 72 untreated high-risk (del17p) MM patients. Mutations were identified in 78% of the patients. While the majority of studied genes were mutated at similar frequency to published literature, the prevalence of TP53 mutation was increased (28%) and no mutations were found in FAM46C. This study provides a comprehensive insight into the mutational landscape of del17p high-risk MM. Additionally, our work demonstrates the practical use of a customized sequencing panel, as an easy, cheap and fast approach to characterize the mutational profile of MM.

Keywords: DNA mutation; DRUG resistance; cancer genetics; genetic analysis; myeloma.

Mutation prevalence in untreated patients with newly diagnosed and untreated del17p multiple myeloma and fluorescence in situ hybridization (FISH) results. All patients had a confirmed del 17p. Grey shading indicates lack of FISH data; black and striped shading indicates, multiple mutations in the same gene and timepoint. No mutation above the chosen threshold was found in CRBN, CUL4A/B, DDB1, EGR1, FAM46C, IRF4, MECOM, NR3C1, PSMB5, PSMG2, PTPRD, RASA2, TIAM1, XBP1 or ZFHX3.
