GATA1 and Diamond-Blackfan anemia: DBA-associated mutations extend beyond ribosomal protein genes to include pathological variants of the X-linked transcription factor GATA1 (Sankaran et al., 2012) and the escortin TSR2 (Gripp et al., 2014) that transfers eS26 (also mutated in DBA) to its binding site on the 90S pre-ribosome in the nucleolus (Schutz et al., 2014).
