Ring sideroblasts can develop as a result of a heme synthesis defect in erythroblasts (ALAS2 mutations), a defect in iron-sulfur cluster assembly, iron-sulfur protein precursor release from mitochondria (ABCB7 mutations), or by a defect in intracellular iron metabolism in erythroid cells (e.g.

The identification of other genes, such as adenosine triphosphate (ATP) binding cassette B7 (ABCB7) and glutaredoxin 5 (GLRX5), has strengthened the role of iron sulfur cluster biogenesis in sideroblast formation and revealed a complex interplay between pathways of mitochondrial iron utilization and cytosolic iron sensing by the iron-regulatory proteins (IRPs).

Reactive oxygen species generated under these conditions might degrade iron-sulfur clusters and lower heme levels in the organelle.

RNA interference of the putative Drosophila orthologue of human ABCB7, a mitochondrial transporter involved in cytoplasmic ISC protein maturation, restored Fer1HCH transcript levels of iron-treated mbn-dmfrn cells to those of control cells grown in normal medium.
