Which form of sickle cell disease is the HbS mutation associated with?

The HbS (c.20A>T) mutation is the most severe mutation associated with sickle cell disease. If two copies of HbS are inherited, the most severe form of the disease (sickle cell anemia) will occur. If only one copy of HbS and one copy of a different mutation (HbC or HbE) is inherited, the disease symptoms are [...]

What are the types of sickle cell disease?

The most severe form of sickle cell disease is HbSS or sickle cell anemia. Other forms of sickle cell diseases include HbSC and HbSE diseases, which generally have less severe symptoms than HbSS disease. Sickle cell mutations can also be inherited with beta thalassemia mutations, resulting in sickle/beta thalassemia disorders of varying severity.
