Hematology. 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 ). Those who are heterozygous for the sickle cell allele produce ...
114,800 (2015) [8] Sickle cell disease ( SCD ), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
The US Food and Drug Administration approved two gene-based treatments for sickle cell disease Friday, including the first therapy that uses the gene-editing technique CRISPR, opening a new era of ...
(Reuters) -The U.S. Food and Drug Administration (FDA) on Friday approved two gene therapies for sickle cell disease, making one of them the first treatment in the United States based on the Nobel ...
The Sickle Cell Disease Association of America, Inc. originated in Racine, Wisconsin. Representatives from 15 different community-based sickle cell organizations came together at Wingspread, a community center, as guest of the Johnson Foundation. There was a common belief that there was a need for national attention to sickle cell disease.
The two gene therapies are the first approved in the U.S. for sickle cell disease. The FDA has previously OK’d 15 gene therapies for other conditions. In the U.S., an estimated 100,000 people ...

Now, 33, Stephenson was one of the first to receive sickle cell gene therapy in a clinical trial six years ago. Before the treatment, Stephenson lived her life on a razor's edge.
Sickle cell-beta thalassemia is caused by inheritance of a sickle cell allele from one parent and a beta thalassemia allele from the other. Mutations. A sickle allele is always the same mutation of the beta-globin gene (glutamic acid to valine at amino acid six). In contrast, beta-thalassemia alleles can be created by many different mutations ...
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.
