WebSickle cell disease is caused by inheriting two copies (one from each parent) of an altered HBB gene, which causes the production of an abnormal form of beta (β)-globin, such as hemoglobin S (HbS). Scientists have identified hundreds of variations in the HBB gene that cause abnormal beta-globin to form and cause disease. WebThe sickle hemoglobin (HbS) occurs as a single nucleotide mutation (GAG/GTG) in the sixth codon of the β-globin gene. This missense mutation results in the substitution of valine for the glutamic acid at the sixth residue of the β-globin chain. This inherited gene occurs in an autosomal dominant fashion.
