In the Baamba population living in the Semliki Forest region in Western Uganda the sickle-cell heterozygote (AS) frequency is 40%, which means that the frequency of the sickle-cell gene is 0.255 and 6.5% of children born are SS homozygotes.
The most dangerous of the sickle cell diseases is known as sickle cell anemia. Sickle cell anemia is the most common homozygous recessive single gene disorder , meaning the affected individual must carry a mutation in both copies of the affected gene (one inherited from each parent) to experience the disease.
Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the context of a population. Genetics has given rise to a number of subfields, including molecular genetics , epigenetics , and population genetics .
The three major types of inherited genetic resistance (sickle-cell disease, thalassaemias, and glucose-6-phosphate dehydrogenase deficiency) were present in the Mediterranean world by the time of the Roman Empire, about 2000 years ago. [19] Molecular methods have confirmed the high prevalence of P. falciparum malaria in ancient Egypt. [20]
Julie Makani (born 1970) is a Tanzanian medical researcher. From 2014 she is Wellcome Trust Research Fellow and Associate Professor in the Department of Haematology and Blood Transfusion at the Muhimbili University of Health and Allied Sciences (MUHAS).
Betibeglogene autotemcel, sold under the brand name Zynteglo, is a gene therapy for the treatment for beta thalassemia. [1] [5] [2] It was developed by Bluebird Bio and was given breakthrough therapy designation by the US Food and Drug Administration in February 2015.
In November 1949, Pauling, Harvey Itano, S. J. Singer and Ibert Wells published "Sickle Cell Anemia, a Molecular Disease" [64] in the journal Science. It was the first proof of a human disease being caused by an abnormal protein, and sickle cell anemia became the first disease understood at the
In Sudan, sickle cell disease was first reported in 1926 by Archibald. [23] The disease is considered one of the major types of anemia, especially in Western Sudan where the sickle cell gene is frequent [24] Sickle cell disease is the major haemoglobinopathy seen in Khartoum, the capital of Sudan. This may be attributed to the migration of ...
