A number sign (#) is used with this entry because Diamond-Blackfan anemia-1 (DBA1) is caused by heterozygous mutation in the gene encoding ribosomal protein S19 (RPS19; 603474) on chromosome 19q13.
DESCRIPTION
Diamond-Blackfan anemia (DBA) is an inherited red blood cell aplasia that usually presents in the first year of life. The main features are normochromic macrocytic anemia, reticulocytopenia, and nearly absent erythroid progenitors in the bone marrow. Patients show growth retardation, and approximately 30 to 50% have craniofacial, upper limb, heart, and urinary system congenital malformations. The majority of patients have increased mean corpuscular volume, elevated erythrocyte adenosine deaminase activity, and persistence of hemoglobin F. However, some DBA patients do not exhibit these findings, and even in the same family, symptoms can vary between affected family members (summary by Landowski et al., 2013). - Genetic Heterogeneity of Diamond-Blackfan Anemia A locus for DBA (DBA2; 606129) has been mapped to chromosome 8p23-p22. Other forms of DBA include DBA3 (610629), caused by mutation in the RPS24 gene (602412) on 10q22; DBA4 (612527), caused by mutation in the RPS17 gene (180472) on 15q; DBA5 (612528), caused by mutation in the RPL35A gene (180468) on 3q29; DBA6 (612561), caused by mutation in the RPL5 gene (603634) on 1p22.1; DBA7 (612562), caused by mutation in the RPL11 gene (604175) on 1p36; DBA8 (612563), caused by mutation in the RPS7 gene (603658) on 2p25; DBA9 (613308), caused by mutation in the RPS10 gene (603632) on 6p; DBA10 (613309), caused by mutation in the RPS26 (603701) gene on 12q; DBA11 (614900), caused by mutation in the RPL26 gene (603704) on 17p13; DBA12 (615550), caused by mutation in the RPL15 gene (604174) on 3p24; DBA13 (615909), caused by mutation in the RPS29 gene (603633) on 14q; DBA14 (300946), caused by mutation in the TSR2 gene (300945) on Xp11.22; and DBA15 (606164), caused by mutation in the RPS28 gene (603685) on 19p13.2. Boria et al. (2010) reviewed the molecular basis of Diamond-Blackfan anemia, emphasizing that it is a disorder of defective ribosome synthesis. Gazda et al. (2012) completed a large-scale screen of 79 ribosomal protein genes in families with Diamond-Blackfan anemia and stated that of the 10 known DBA-associated genes, RPS19 accounts for approximately 25% of patients; RPS24, 2%; RPS17, 1%; RPL35A, 3.5%; RPL5, 6.6%; RPL11, 4.8%; RPS7, 1%; RPS10, 6.4%; RPS26, 2.6%; and RPL26, 1%. Gazda et al. (2012) stated that in total these mutations account for approximately 54% of all DBA patients.CLINICAL FEATURES
Diamond et al. (1961) observed triphalangeal thumbs in 1 of 30 patients with congenital erythroid hypoplastic anemia. Alter (1978) pointed out that triphalangeal thumbs occurred in 6 of 133 cases of congenital hypoplastic anemia. In all, 45 of the 133 cases (34%) had associated hand anomalies of some kind. Cathie (1950) described a similar facial appearance in 4 unrelated affected children with erythrogenesis imperfecta, including snub noses, thick upper lips, and widely separated eyes. A propensity for the development of leukemia has been reported (Krishnan et al., 1978; Wasser et al., 1978). Ball et al. (1996) analyzed retrospective data from 80 cases of DBA (33 male, 47 female) born in the U.K. in a 20-year period (1975-1994), representing an annual incidence of 5 per million live births. Ten children from 7 families had an apparently familial disorder. ... More on the omim web site
