FOIA Primary role for adherent leukocytes in sickle cell vascular occlusion: a new paradigm. As noted, complete elimination of the mutant gene is not required for clinical improvement to be seen because diminution of hemoglobin S gene expression to 50% has been demonstrated to be sufficient to allow a phenotype similar to sickle trait.90. 2022 Jul 11. Since then, the treatment of sickle cell has taken to new heights by introducing several new agents (voxelotor, crinzalizumab, L-glutamine), and most recently, gene therapy. In an open-label pilot clinical trial of the drug, all patients achieved normalization of nicotinamide adenine dinucleotide redox potential and a decrease in permanently sickled cells in peripheral blood.104 Only 7 adult patients participated in the trial, and no clinical benefit was seen. In 1949, independent reports from Dr. James V Neel and Col. E. A. Beet described the patterns of inheritance in patients with SCD. Patients of Arab-Indian haplotype generally manifest high hemoglobin F levels (approximately 20%) and have a mild clinical phenotype of sickle cell disease.72,73 Likewise, patients who are compound heterozygotes for hereditary persistence of fetal hemoglobin (up to 30% hemoglobin F) have few if any manifestations of the disorder.74 Therefore, the assumption seemed reasonable that inducing hemoglobin F in individuals in which it had been turned off might accrue considerable benefit to patients with sickle cell disease.

Also discussed is stem cell transplantation that, to date, is the only curative approach for this disease, as well as the current status of gene therapy. Despite concerns about off-target activity of CRISPR/Cas9 or similar nuclease or vector insertional error, no adverse effects were related to the lentiviral transduction of the stem cells, perhaps because lentiviruses tend to insert themselves randomly with a bias toward integration into areas of already expressed genes, thereby minimizing transactivation of nearby genes. Also, a clear relationship must be established between transplantation outcomes and improved quality of life, a relationship that to date has not been seen consistently or definitively. Good Essays.
