Resequencing analysis of the candidate tyrosine kinase and RAS pathway gene families in multiple myeloma.

ABSTRACT: Multiple myeloma (MM) is an incurable, B-cell malignancy characterized by the clonal proliferation and accumulation of malignant plasma cells in bone marrow. Despite recent advances in the understanding of genomic aberrations, a comprehensive catalogue of clinically actionable mutations in MM is just beginning to emerge. The tyrosine kinase (TK) and RAS oncogenes, which encode important regulators of various signaling pathways, are among the most frequently altered gene families in cancer. To clarify the role of TK and RAS genes in the pathogenesis of MM, we performed a systematic, targeted screening of mutations on prioritized RAS and TK genes, in CD138-sorted bone marrow specimens from 42 untreated patients. We identified a total of 24 mutations in the KRAS, PIK3CA, INSR, LTK, and MERTK
