Frequency of FLT3 ITD and FLT3 TKD Mutations in Multiple Myeloma Patients (A Case Control Study)
Journal Title: International Journal of Medical Laboratory - Year 2015, Vol 2, Issue 1
Abstract
Background and Aims: Multiple myeloma is a malignant proliferation of plasma cells derived from a single clone. The tumor, its products and the host response lead to organ damages. Some factors that are responsible in its pathogenesis are recognized. As FMS like Tyrosine Kinase 3 receptor (FLT3) mutation has been proved as a determining factor in leukemic patients the goal of this study was to find association of FLT3 internal tandem duplication (ITD) and FLT3 tyrosine kinase domain (TKD), mutations with multiple myeloma. Materials and Methods: This case-control study was conducted on 60 paraffin-embedded bone marrow biopsies (30 multiple myeloma and 30 normal bone marrow specimens) in the pathology departments of Ghaem and Imam Reza hospitals in Mashhad. After sections preparation, DNA was extracted and two PCR reactions were set up for detection of FLT3/ ITD and FLT3/TKD mutations. Results: The Mean age of samples was 64±10 years. No FLT3 mutations were detected in multiple myeloma patients. Conclusions: Our findings showed that FLT3 mutations occurrence seem unusual in multiple myeloma.
