Questions have emerged regarding whether or not genetic clusters support the idea of race as a valid construct to apply to medical research and treatment of disease, because there are many diseases that correspond with specific genetic markers and/or with specific populations, as seen with Tay-Sachs disease or sickle cell disease.
The Food and Drug Administration must decide by Friday whether to approve a new gene-editing therapy to treat sickle cell disease, a debilitating blood disorder that affects at least 100,000 ...
To balance this loss of sickle-cell genes, a mutation rate of 1:10.2 per gene per generation would be necessary. This is about 1000 times greater than mutation rates measured in Drosophila and other organisms and much higher than recorded for the sickle-cell locus in Africans. [70]
Genetics is the study of genes, genetic variation, and heredity in organisms. [1] [2] [3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance ...
Sickle cell-Hb Lepore Boston syndrome is a type of sickle cell disease (HbS) that differs from homozygous sickle cell disease where both parents carry sickle hemoglobin. In this variant one parent has the sickle cell hemoglobin the second parent has Hb Lepore Boston, the only one of the three variants described in association with HbS.

It can be prevented if one parent has normal genes, giving rise to screenings that empower carriers to select partners with normal hemoglobin. 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.
The FDA is expected to decide on the second gene therapy for sickle cell, made by Bluebird Bio, before the end of the year. Bluebird's treatment works differently. It aims to add functional copies ...
