Recurrent somatic mutations in SF3B1 have been identified in patients with myelodysplastic syndromes (MDS) and are associated with ring sideroblasts (RS) and relatively favorable clinical outcomes. The 2016 World Health Organization classification categorizes patients with ≥ 5% RS and SF3B1 mutation as MDS-RS, in contrast to its prior MDS-RS classification (≥ 15% RS, no genotyping data).

AU - Tefferi, Ayalew. AU - Patnaik, Mrinal M. PY - 2018/1/1. Y1 - 2018/1/1 §Ring sideroblasts ≥ 15% were present in 142 (71.7%) of 198 sequenced patients with gene mutation data (see text for SF3B1 gene mutation incidence). RBC Transfusion Independence The proportion of patients who achieved RBC-TI ≥ 8 weeks was significantly higher in the lenalidomide group (26.9%) than in the placebo group (2.5%; Fisher exact P < .001; Table 2 ). 2016-01-01 · The accurate classification of 5q minus syndrome with a JAK2 V617F mutation is yet not determined, especially in patients with additional presence of ring sideroblasts. The case described above responded well to the treatment with lenalidomide, which is commonly seen in patients with isolated 5q minus deletion MDS but much less often in patients with other types of low grade MDS [9] , [13] .

2010; 116(2):180-2 (ISSN: 1528-0020) Median time from diagnosis to treatment was 12.4 months (range 2.1-47.4). Median number of prior therapies was 1 (range 0-3). Three patients received lenalidomide frontline therapy. Overall, 3/7 patients (43%) responded to lenalidomide therapy. Four patients were red cell transfusion dependent at the time of lenalidomide initiation. 1 DISEASE OVERVIEW. Ring sideroblasts (RS) are erythroid precursors in which after Prussian blue staining (Perls reaction) there are a minimum of five siderotic granules covering at least a third of the nuclear circumference (Figure 1).

Normally, sideroblasts are present in the bone marrow, and enter the circulation after maturing into a normal erythrocyte. The presence of sideroblasts per se does not define sideroblastic anemia. Only the finding of ring (or ringed) sideroblasts characterizes sideroblastic anemia.
