It commonly presents with congenital bony malformations (50% of the cases) and growth retardation (30% of cases).[3] The median age of presentation and diagnosis is 2 months of age.[2][3] Children usually first present with lethargy and pallor. [statpearls.com]
Presentation[1] The severity of symptoms is variable but is often severe and life-threatening. Usually it presents in the first few months of life when a young child develops a severely hypoplastic macrocytic anaemia. [patient.info]

Malformations are seen more frequently with DBA6 RPL5 and DBA7 RPL11 mutations.[5] The genetic abnormalities underpinning the combination of DBA with Treacher Collins syndrome (TCS)/mandibulofacial dysostosis (MFD) phenotypes are heterogeneous, including [en.wikipedia.org]

"As in human patients, blood development in our fish mutant was blocked at the pro-erythroblast stage," explains Zon. "But if we took out p53 and blocked cell death, red blood cells would appear. [medicalxpress.com]

Workup
Laboratory workup is significant for elevated MCV and erythrocyte adenosine deaminase (eADA). [statpearls.com]
It is therefore essential that DBA be considered in the workup of any infant presenting with anemia. We present the first known recorded case of DBA in South Africa. [jmedicalcasereports.biomedcentral.com]
Treatment
Besides the patients who are on steroid treatment are also prone to hepatic iron laoding. [library.ehaweb.org]

Prognosis
Prognosis The prognosis is generally good. However, complications of treatment and a higher incidence of cancer may reduce life expectancy. Disease severity depends on the quality and response to treatment. [orpha.net]

Prognosis is relatively good, but complications related to treatment may alter the patient's quality of life.[2] Severe complications as a result of treatment or the development of cancer may reduce life expectancy.[2] Disease severity is determined [statpearls.com]
Etiology
[…] chronic circulation clinical clot coagulation condition congenital congestive heart failure coronary arteries cyanosis death defect diagnosis digitalis dilatation disorder doses ductus dyspnea edema electrocardiogram endocarditis enlarged erythrocytes etiology [books.google.es]
Detailed Description: Diamond Blackfan anemia (DBA) is a constitutional pure red cell aplasia of unknown etiology. There is laboratory evidence for an immune mechanism and most patients respond to corticosteroids. [clinicaltrials.gov]
Etiology At present, disease-causing mutations are identified in 40-45% of patients. All involved genes code for ribosomal proteins (RPs) from either the small (RPS7, RPS17, RPS19, RPS24) or the large (RPL5, RPL11, RPL35a) ribosomal subunit. [orpha.net]
No extrinsic etiologic mechanisms were identified. Evidence of anemia was long-standing and varied in severity. [amjmed.com]
Iron deficiency anemia is the most common type of anemia worldwide in all the age groups.[1] However, here we talk about a rare type of anemia with genetic etiology. [statpearls.com]
Epidemiology
Summary Epidemiology Annual incidence in the general population of Europe is estimated at around 1/150,000. Both sexes are equally affected and no ethnic predisposition has been identified. [orpha.net]

Prevention
Patients with DBA should be screened for iron loading as early as possible and chelation treatment should be initiated to prevent the related morbidity and mortalities. Session topic: 12. Bone marrow failure syndromes incl. [library.ehaweb.org]
MRI can be used as a non-invasive tool to recognize pituitary IOL and identification of proper chelation therapy for the prevention of irreversible pituitary tissue damage. [abstracts.eurospe.org]
Treatment may include iron chelation drugs that remove iron from the blood to prevent complications. [stanfordchildrens.org]
How can Diamond-Blackfan anemia be prevented? As with most genetic diseases, there are no known methods to prevent the disease. [cancertherapyadvisor.com]
It is advised to carefully taper low maintenance doses to prevent overshooting the individual minimal effective dose. [onlinelibrary.wiley.com]
