Genes affected

CDIN1 (HGNC:26929): (CDAN1 interacting nuclease 1) This gene encodes a protein with two predicted helix-turn-helix domains. Mutations in this gene were found in families with congenital dyserythropoietic anemia type Ib. Alternative splicing results in multiple transcript variants encoding different isoforms.
