Pearson syndrome in a Diamond-Blackfan anemia cohort.
In this issue of Blood, Gagne et al describe a cohort of 362 patients clinically classified as having Diamond-Blackfan anemia (DBA), in which 175 (48%) were found to have mutations and deletions in ribosomal protein genes or GATA1, and 8 of the remaining patients (2.2% overall) had mitochondrial gene deletions consistent with Pearson marrow-pancreas syndrome (PS). The authors propose that all p...
متن کاملPearson marrow pancreas syndrome in patients suspected to have Diamond-Blackfan anemia.
Pearson marrow pancreas syndrome (PS) is a multisystem disorder caused by mitochondrial DNA (mtDNA) deletions. Diamond-Blackfan anemia (DBA) is a congenital hypoproliferative anemia in which mutations in ribosomal protein genes and GATA1 have been implicated. Both syndromes share several features including early onset of severe anemia, variable nonhematologic manifestations, sporadic genetic oc...

متن کاملDiamond Blackfan anemia.
Mutations affecting genes encoding ribosomal proteins cause Diamond Blackfan anemia (DBA), a rare congenital syndrome associated with physical anomalies, short stature, red cell aplasia, and an increased risk of malignancy. p53 activation has been identified as a key component in the pathophysiology of DBA after cellular and molecular studies of knockdown cellular and animal models of DBA and o...
متن کاملDiamond-Blackfan anemia.
Diamond-Blackfan anemia (DBA) is a rare, congenital, hypoplastic anemia that usually presents in early infancy. Congenital anomalies, particularly of the head and upper limbs, are present in about a quarter of reported patients. The disease is characterized by a moderate-to-severe macrocytic anemia, occasional neutropenia or thrombocytosis, a normocellular bone marrow with erythroid hypoplasia,...
