To date, mutations in 19 ribosomal genes (RPS7, RPS10, RPS15A, RPS17, RPS19, RPS24, RPS26, RPS27, RPS28, RPS29, RPL5, RPL11, RPL15, RPL18, RPL26, RPL27, RPL31, RPL35, RPL35A) and 3 non-ribosomal genes (GATA1, TSR2, EPO) have been implicated in DBA [9]. This evidence concerns the gene RPS27 and Diamond-Blackfan anemia.
