Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. The most common type is known as sickle cell anemia. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells.
So far, the two gene therapies for sickle cell have only been approved in wealthier countries: both of them in the U.S., and one in Britain and Bahrain as well.
A study aimed at detecting the genes that could give rise to offspring with sickle cell disease. Patients diagnosed with beta thalassemia have MCH ≤ 26 pg and an RDW < 19. Of 10,148 patients, 1,739 patients had a hemoglobin phenotype and RDW consistent with beta thalassemia.
Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous).
LONDON (AP) — Britain’s medicines regulator has authorized the world’s first gene therapy treatment for sickle cell disease, in a move that could offer relief to thousands of people with the...
Sickle cell – The gene for HbS associated with sickle-cell is today distributed widely throughout sub-Saharan Africa, the Middle East, and parts of the Indian subcontinent, where carrier frequencies range from 5–40% or more of the population.
So far, the two gene therapies for sickle cell have only been approved in wealthier countries: both in the U.S., and one in Britain and Bahrain as well.
Sickle cell is the most common disease to receive approval for gene therapy treatment, following decades of development and years of approvals for therapy for people with rarer conditions.
Those who have minor degrees of thalassemia, in common with those who have sickle-cell trait, have some protection against malaria, explaining why sickle-cell trait and thalassemia are more common in regions of the world where the risk of malaria is higher.
The US Food and Drug Administration on Friday approved two gene-based treatments for sickle cell disease, including the first therapy that uses the gene-editing technique CRISPR, opening...
