Article Synopsis
  • Congenital anemias are diverse disorders caused by abnormalities in red blood cells and can involve defects in enzymes, membranes, and hemoglobin, presenting with varying severity and symptoms.
  • The study utilized Quant 3' mRNA-Sequencing to analyze gene expression in patients with sickle cell disease, thalassemia, and a rare form of congenital sideroblastic anemia (CSA), revealing distinct gene expression patterns.
  • Results indicated that most congenital anemias showed upregulated genes related to metabolic processes and erythropoiesis, while the CSA patient exhibited a unique gene map, highlighting the clinical significance of these findings in understanding anemia mechanisms.

Hereditary spherocytosis (HS) is a membranopathy that impacts the vertical junctions between the cytoskeleton and the plasma membrane of erythrocytes. The gold standard method for diagnosing it is osmotic gradient ektacytometry (OGE). However, access to this technique is scarce.

Fanconi anemia (FA) is a rare inherited disorder that mainly affects the bone marrow. This condition causes decreased production of all types of blood cells. FA is caused by a defective repair of DNA interstrand crosslinks and to date, mutations in over 20 genes have been linked to the disease.

Hereditary pyropoikilocytosis (HPP) is characterised by severe hemolytic anemia due to membrane instability. We report the case of a 13-day-old boy with neonatal jaundice and severe hemolytic anemia. A peripheral smear examination showed severe anisopoikylocytosis.

Ubiquitin-fold modifier 1 (UFM1) is involved in neural and erythroid development, yet its biological roles in these processes are unknown. Here, we generated zebrafish models deficient in and that exhibited telomere shortening associated with developmental delay, impaired hematopoiesis and premature aging. We further report that HeLa cells lacking UFL1 have instability of telomeres replicated by leading-strand synthesis.
