Hope for Rare Anemia Patients: Czech Scientists Create “Perfect” Mouse Model to Test New Drugs

January 19, 2026

Czech researchers have made a significant breakthrough in the study of Diamond-Blackfan Anaemia (DBA), a rare genetic disease that causes severe anemia and congenital malformations in children. Scientists from the Czech Centre for Phenogenomics (Institute of Molecular Genetics of the Czech Academy of Sciences) and the First Faculty of Medicine at Charles University (BIOCEV) developed a unique mouse model that accurately reproduces the disease. This achievement could help researchers develop safer and more effective treatments.

DBA occurs when the body cannot properly assemble ribosomes, the cellular structures responsible for producing proteins. As a result, the body stops producing enough red blood cells, leading to severe anemia. Patients often also suffer from developmental defects, including heart and organ malformations or growth problems. Until now, research was limited because earlier attempts to create animal models failed, mice with the defect died before birth, preventing further study and testing of potential therapies.
