Clinical Significance
Mendelian inheritance allows S hemoglobin to manifest itself in two manners: (1) as a homozygous condition(S/S) known as sickle cell disease, and (2) as a heterozygous condition where the sickle hemoglobin is present with other hemoglobin, such as hemoglobin A, hemoglobin C, Hemoglobin D, etc. Solubility tests differentiate between sickling and non-sickling hemoglobin but do not distinguish the hemoglobin type.
