GATA1 protein synthesis is reduced in Diamond-Blackfan anemia (DBA), a congenital red cell aplasia caused by reduced biosynthesis of ribosomes, and mutations in GATA1 can cause a DBA-like phenotype (Ludwig et al., 2014; Vlachos et al., 2014; Paolini et al., 2016). Here, GATA1 is linked to Diamond-Blackfan anemia.
