In this issue of Blood, Wlodarski and colleagues demonstrate that as many as 72% of adolescents diagnosed with myelodysplastic syndrome (MDS) and monosomy 7 harbor germline mutations in GATA2.1 Although pediatric MDS is a very rare diagnosis, occurring in 0.8 to 4 cases per million,2 Wlodarski et al screened >600 cases of primary or secondary MDS in children and adolescents who were enrolled in the European Working Group on MDS consortium over a period of 15 years. The overall frequency of germline GATA2 mutations in children with primary MDS was 7%, and 15% in those presenting with advanced disease. Notably, mutations in GATA2 were absent in patients with therapy-related MDS or acquired aplastic anemia.
