The decreased transcription of a crucial erythropoietic factor, MYB (v-myb avian myeloblastosis viral oncogene homolog), has been reported in erythroid progenitors from DBA patients (Gazda et al., 2006a) and in Rpl11-deficient zebrafish (Danilova et al., 2011). This evidence concerns the gene RPL11 and Diamond-Blackfan anemia.
