Overview

NCI Definition: A myelodysplastic syndrome characterized by an anemia in which 15% or more of the erythroid precursors are ring sideroblasts. The ring sideroblast is an erythroid precursor in which one third or more of the nucleus is encircled by granules which are positive for iron stain. (WHO, 2001) [1]

Refractory anemia with ring sideroblastss most frequently harbor alterations in SF3B1, TET2, DNMT3A, ASXL1, and TP53 [2].

Most Commonly Altered Genes in Refractory anemia with ring sideroblasts

SF3B1 Mutation, SF3B1 K700E, SF3B1 Exon 15 Mutation, SF3B1 Codon 700 Missense, and SF3B1 Exon 14 Mutation are the most common alterations in refractory anemia with ring sideroblasts [2].
