New variants that could be involved in the pathogenesis of these diseases have been identified.Ĭitation: del Rey M, Benito R, Fontanillo C, Campos-Laborie FJ, Janusz K, Velasco-Hernández T, et al. The deregulation of genes involved in iron and mitochondrial metabolism provides new insights in our knowledge of MDS-RS. Moreover, significant differences were observed between patients with SF3B1 mutations and patients without the mutations. Thus mitochondrial transporters SLC25 ( SLC25A37 and SLC25A38) and ALAD genes were over-expressed in RARS. Gene expression analysis revealed that iron metabolism and mitochondrial function had the highest number of genes deregulated in RARS patients compared to controls and the refractory cytopenias with unilineage dysplasia (RCUD). A total of 231 low-risk MDS patients and 81 controls were studied. In order to gain insight in the molecular basis of MDS-RS, an integrative study of the expression and mutational status of genes related to iron and mitochondrial metabolism was carried out. However, the mechanisms responsible for iron accumulation that characterize the Myelodysplastic Syndrome with ring sideroblasts (MDS-RS) are not completely understood. The presence of SF3B1 gene mutations is a hallmark of refractory anemia with ring sideroblasts (RARS). ![]()
