A novel mutation of ribosomal protein S10 gene in a Japanese patient with diamond-Blackfan anemia.

Diamond-Blackfan anemia (DBA) is an inherited bone marrow disease. The condition is characterized by anemia that usually presents during infancy or early childhood and congenital malformation. Several reports show that DBA is associated with mutations in the ribosomal protein (RP) genes, RPS19, RPS24, RPS17, RPL35A, RPL5, RPL11, and RPS7. Recently, 5 and 12 patients with mutations in RPS10 and RPS26, respectively, were identified in a cohort of 117 DBA probands. Therefore, we screened the DBA patients who were negative for mutations in these DBA genes for mutations in RPS10 and RPS26. The present case report describes the identification of the first Japanese DBA patient with a novel mutation in RPS10.
