KIF23 and congenital dyserythropoietic anemia: CDA‐III is the rarest subtype of dyserythropoietic anemia, usually inherited as an autosomal dominant disorder due to mutations in the KIF23 gene that codes for Mitotic Kinesin‐Like Protein 1 (MKLP1), a centralspindlin component important for cytokinesis [1, 2, 3].
