Myelodysplastic syndrome with ring sideroblasts
MONDO:0019157Acquired idiopathic sideroblastic anemia is one of a group of disorders known as the myelodysplastic syndromes (MDS) characterized by ineffective haemopoiesis affecting one or more blood cell lineages (myeloid, erythroid or megakaryocytic) leading to peripheral blood cytopenias and an increased risk of developing leukemia. Acquired idiopathic sideroblastic anemia is now more commonly referred to as refractory anemia with ringed sideroblasts or the acronym RARS.
Also known as: AISA, MDS with ring sideroblasts, MDS-RS, Pure sideroblastic Anaemia, Pure sideroblastic Anemia, RARS, acquired idiopathic sideroblastic anaemia, acquired idiopathic sideroblastic anemia

Blood bank aims to predict leukemia risk in MDS patients
Knowledge-focused Recruiting nowThis study gathers blood and bone marrow samples from 150 adults with myelodysplastic syndrome (MDS), a blood disorder that can turn into acute leukemia. Researchers want to find biological markers that help predict which patients are likely to progress to leukemia. The goal is t…
