We report the case of a 28-year-old female followed for congenital dyserythropoiesis type I which required repeated transfusions. Alpha-2a interferon treatment was started because of post-transfusion chronic viral hepatitis type C. Following this treatment, haemoglobin level increased and reached normal value during the 24 weeks of interferon treatment. When interferon therapy was stopped, haemoglobin level returned to previous values, requiring more transfusions. Resumption of interferon therapy resulted again in a complete normalization of haemoglobin level. Erythrokinetic studies demonstrated a striking reduction of the ineffective erythropoiesis, and electron microscopy study a reduction in nuclear structure abnormalities. To our knowledge, this is the first report of the efficacy of interferon in congenital dyserythropoiesis.

A novel nonsense RPS26 mutation in a patient with Diamond-Blackfan anemia: a case report.
J Med Case Rep

Department of Medical Genetics, Adana Faculty of Medicine, Adana City Education and Research Hospital, University of Health Sciences, Adana, Turkey.
Article Synopsis
- Diamond-Blackfan anemia is a rare genetic disorder linked to mutations in ribosomal protein genes, and this report introduces a new variant in the RPS26 gene that hasn't been previously documented.
- A 16-month-old Turkish girl was diagnosed with the condition, showing symptoms like pallor and macrocytosis, with genetic testing revealing the novel c.221G>T (p.C74F) mutation in the RPS26 gene.
- This discovery highlights the complexity of Diamond-Blackfan anemia's genetic diversity and emphasizes the importance of genetic testing for accurate diagnosis and potential future treatments.
Long-term hematopoietic dysfunction in patients with large-scale mitochondrial DNA deletion syndromes.

Article Synopsis
- Pearson syndrome (PS) and Kearns-Sayre syndrome (KSS) are mitochondrial DNA deletion syndromes with PS causing severe childhood cytopenia and KSS having later onset without blood-related issues, both sharing a common mitochondrial DNA deletion.
- A study of 16 patients revealed that 75% had cytopenia, with many needing blood transfusions, and even after achieving transfusion independence, they showed persistent bone marrow (BM) dysfunction.
- The research highlights that BM dysfunction is a consistent finding in SLSMD syndromes, which raises concerns about potential clonal evolution and chromosome 7 abnormalities, underscoring the need for specialized hematological monitoring for these patients.
Non-syndromic congenital sideroblastic anaemia; phenotype, and genotype of 15 Indian patients.

Article Synopsis
- * The study involves identifying CSA patients using a targeted next-generation sequencing (t-NGS) panel, discovering mutations related to microcytic anaemia, and assessing their response to treatments such as pyridoxine and blood transfusions.
- * Researchers found various genetic variants among patients, primarily in European populations, and used PyMoL software to study how these mutations affect protein structure and function, aiming for a deeper understanding of CSA genetics.
Congenital dyserythropoietic anemias (CDAs) are rare hereditary disorders, of which type II CDA is the most common. Mutations in the gene located on chromosome 20 result in this autosomal recessive disorder. In this case report, we present a case of CDA II with unique biopsy findings being detected via genetic testing.

Article Synopsis
- Hereditary dyserythropoietic anemias (CDAs) are rare genetic disorders that disrupt normal blood cell development, leading to ineffective red blood cell production and low blood cell counts.
- The identification of new genes linked to CDAs through advanced genetic sequencing has improved diagnosis and helped scientists understand how these conditions work at a biological level.
- Current treatments focus on supportive care, but recent insights into genetic mechanisms may open up new therapeutic options for managing these anemias.
