Diamond-Blackfan anemia: erythropoiesis lost in translation

Blood. 2007 Apr 15;109(8):3152-4. doi: 10.1182/blood-2006-09-001222. Epub 2006 Dec 12.

Abstract

Diamond-Blackfan anemia (DBA) is a congenital erythroid aplasia that usually presents as macrocytic anemia during infancy. Linkage analysis suggests that at least 4 genes are associated with DBA of which 2 have been identified so far. The known DBA genes encode the ribosomal proteins S19 and S24 accounting for 25% and 2% of the patients, respectively. Herein, we review possible links between ribosomal proteins and erythropoiesis that might explain DBA pathogenesis. Recent studies and emerging findings suggest that a malfunctioning translational machinery may be a cause of anemia in patients with DBA.
