Although CECR1 mutations are known as DADA2 deficiency, which causes a wide range of phenotypes such as intermittent fevers, stroke, and polyarteritis nodosa, it is not yet known by which mechanism it causes DBA-like phenotype (Sasa et al., 2015; Ulirsch et al., 2018). This evidence concerns the gene ADA2 and Diamond-Blackfan anemia.
