L-Leucine alleviates Diamond-Blackfan anemia.
D iamond-Blackfan anemia (DBA) is a rare genetic disease resulting from sporadic mutations and occasional autosomal-dominant inheritance. Almost uniformly, patients manifest in the newborn period with a macrocytic anemia, occasional multilineage cytopenias, variable developmental abnormalities, and a propensity for cancer.3,4 Underlying mutations in 9 genes encoding ribosomal proteins (RPs) hav...
متن کاملDietary L-leucine improves the anemia in a mouse model for Diamond-Blackfan anemia.
Diamond-Blackfan anemia (DBA) is a congenital erythroid hypoplasia caused by a functional haploinsufficiency of genes encoding for ribosomal proteins. Recently, a case study reported a patient who became transfusion-independent in response to treatment with the amino acid L-leucine. Therefore, we have validated the therapeutic effect of L-leucine using our recently generated mouse model for RPS...
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,...
متن کاملIncidence of neoplasia in Diamond Blackfan anemia: a report from the Diamond Blackfan Anemia Registry.
Diamond Blackfan anemia (DBA) is an inherited bone marrow failure syndrome characterized by red cell aplasia and congenital anomalies. A predisposition to cancer has been suggested but not quantified by case reports. The DBA Registry of North America (DBAR) is the largest established DBA patient cohort, with prospective follow-up since 1991. This report presents the first quantitative assessmen...
