HBB protein is produced by the gene HBB which is located in the multigene locus of β-globin locus on chromosome 11, specifically on the short arm position 15.4. Expression of beta globin and the neighbouring globins in the β-globin locus is controlled by single locus control region (LCR), the most important regulatory element in the locus located upstream of the globin genes.

A single point mutation in this polypeptide chain, which is 147 amino acids long, results in the disease known as Sickle Cell Anemia. [18] Sickle-cell anemia is an autosomal recessive disorder that affects 1 in 500 African Americans, and is one of the most common blood disorders in the United States. [17]
Proliferative sickle retinopathy is the most severe ocular complication of sickle cell disease. Even though PSCR begins in the first decade of life, the condition remains asymptomatic and unnoticed until visual symptoms occur due to vitreous hemorrhage or retinal detachment.
The same gene variant, or group of gene variants, may produce different effects in different populations depending on differences in the gene variants, or groups of gene variants, they interact with. One example is the rate of progression to AIDS and death in HIV –infected patients.
Logo of the Human Genome Project. The Human Genome Project (HGP) was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying, mapping and sequencing all of the genes of the human genome from both a physical and a functional standpoint.
The film features the story of David Sanchez, a young man with sickle cell disease. [6] He is first featured in the hospital, sharing his experience as he gets a red blood cell transfusion. This treatment is currently one of the only available for people with sickle cell to help manage severe pain crises.
The work of MAP falls into three areas: Estimation of the spatial distribution of malaria prevalence and incidence and related topics, such as the spatial distribution of insecticide treated nets, antimalarial drugs, mosquito vectors, and human blood disorders; Disseminating data on malaria via the Repository for Open Access Data (ROAD-MAP) project
