Introduction. Sickle cell disease (SCD) is a collection of disorders characterized by the inheritance of a single base substitution (replacement of hydrophilic glutamic acid by hydrophobic valine) in the first exon of the β-globin gene (HBB).

Aug 22, 2022 · 1.1. Case Description. A 23-year-old male had severe HbSS disease diagnosed at birth with an extensive history of complications. His sickle cell anemia required chronic monthly RBC transfusions and multiple RBC exchange transfusions (approximately 100 transfusions over his lifetime), resulting in hemochromatosis necessitating oral iron chelation therapy. BCL11A is a transcription factor that represses γ-globin expression and fetal hemoglobin in erythroid cells. We performed electroporation of CD34+ hematopoietic stem and progenitor cells obtained from healthy donors, with CRISPR-Cas9 targeting the BCL11A erythroid-specific enhancer.In individuals with Sickle Cell Anemia, the altered hemoglobin, known as hemoglobin S, causes red blood cells to take on a characteristic sickle shape. This abnormal shape hinders the cells' flexibility, leading to blockages in blood vessels, reduced oxygen delivery to tissues, and a range of associated health issues.Sickle cell disease (SCD) is the most common monogenic hematologic disorder and is essentially congenital hemolytic anemia caused by an inherited point mutation in the β-globin on chromosome 11. ...

The proof-of-principle experiments have proven the possibility of SCD mutation correction and fetal hemoglobin (HbF) induction in SCD derived HSCs and iPSCs, and subsequent normal red blood cell derivation for transfusion purposes. Sickle cell disease (SCD) is an autosomal recessive disease in which homozygosity for a single point mutation in the gene encoding the β-globin chain produces hemoglobin S molecules that polymerize within the erythrocyte during deoxygenation; the result is sustained hemolytic anemia and vaso-occlusive events.
