WebSickle hemoglobin (HbS) is caused by a mutation in the β globin gene which affects the stability and solubility of the β chain. When HbS is deoxygenated (e.g. during inflammation, infection, dehydration or hypoxia) it polymerizes and distorts the red cell, eventually resulting in the characteristic sickle shape. WebHemoglobin variants occur when there are genetic changes in specific genes, or globins, that cause changes or alterations in the amino acid. They could affect the structure, behavior, the production rate, and/or the stability of that specific gene. Usually there are four genes that code for alpha globin and two genes that code for beta globin.

"WebA human gene called the β-globin gene encodes a polypeptide that functions as a subunit of the protein known as hemoglobin. Hemoglobin carries oxygen within red blood cells. In human populations, the β-globin gene can be found as the more common allele called the HbA allele, but it can also be found as theHbS allele. " - Hemoglobin gene mutation

Hemoglobin Mutations Cause Sickle Cell Disease

WebOne of the haplotypes included a cytosine-to-thymine point mutation 196 nucleotides upstream from the A-gamma-globin gene (142200.0027). The gamma-A mutation at position -196 is associated with high levels of production of fetal hemoglobin. The beta-39 nonsense mutation may have gotten onto the -196 chromosome through crossing-over. WebThalassemia is the most common inherited blood disorder in Southeast Asia, which is caused by reduced or absent synthesis of the globin chains of hemoglobin leading to imbalance of the globin chains. α-Thalassemia is one of the major thalassemia types and is caused by mutation in either α 1-globin gene (HBA1) or α 2-globin gene (HBA2) on …

WebHemoglobin is a protein that carries oxygen throughout the body. A mutation in the HBB gene causes hemoglobin to clump together and change the shape of red blood cells. This can lead to anemia and blocked blood flow for people with SCD. SCD can only be inherited if each parent passes down a mutated HBB gene. This means it is a recessive trait.
