WebNational Center for Biotechnology Information 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.
