Novel deletion of RPL15 identified by array-comparative genomic hybridization in Diamond-Blackfan anemia.

ABSTRACT: Diamond-Blackfan anemia (DBA) is an inherited red blood cell aplasia that usually presents during the first year of life. The main features of the disease are normochromic and macrocytic anemia, reticulocytopenia, and nearly absent erythroid progenitors in the bone marrow. The patients also present with growth retardation and craniofacial, upper limb, heart and urinary system congenital malformations in ~30-50 % of cases. The disease has been associated with point mutations and large deletions in ten ribosomal protein (RP) genes RPS19, RPS24, RPS17, RPL35A, RPL5, RPL11, RPS7, RPS10, RPS26, and RPL26 and GATA1 in about 60-65 % of patients. Here, we report a novel large deletion in RPL15, a gene not previously implicated to be causative in DBA. Like RPL26, RPL15 presents the distinctive feat
