Aside from sideroblastic anemia, variants in the PUS1 gene, which plays an essential role in tRNA function and in stabilizing the secondary and tertiary structure of many RNAs, and in the SLC25A38 gene, which is required during erythropoiesis and is essential for the biosynthesis of heme, were associated with a DBA-like phenotype. This evidence concerns the gene SLC25A38 and sideroblastic anemia.
