Next‐generation sequencing ( NGS ) is rapidly changing the clinical care of patients with myelodysplastic syndrome ( MDS ). NGS can be used for various applications: (i) in the diagnostic process to discriminate between MDS and other diseases such as aplastic anaemia, myeloproliferative disorders and idiopathic cytopenias; (ii) for classification, for example, where the presence of SF 3B1 mutation is one criterion for the ring sideroblast anaemia subgroups in the World Health Organization 2016 classification; (iii) for identification of patients suitable for targeted therapy (e.g. IDH 1/2 inhibitors); (iv) for prognostication, for example, where specific mutations (e.g. TP 53 and RUNX 1 ) are associated with inferior prognosis, whereas others (e.g. SF 3B1 ) are associated with superior prognosis; and (v) to monitor patients for progression or treatment failure. Most commonly, targeted sequencing for genes (normally 50–100 genes) reported to be recurrently mutated in myeloid disease is used. At present, NGS is rarely incorporated into clinical guidelines although an increasing number of studies have demonstrated the benefit of using NGS in the clinical management of MDS patients.
