Comments: The substitution of Glutamic Acid (Glu) with Lysine (Lys) at the sixth position of the beta-globin chain induces an electrostatic interaction between positively charged β6-Lys groups and negatively charged adjacent molecules, leading to the decreased solubility of HbC in red cells. Due to this, crystal formation occurs, leading to increased blood viscosity and decreased red blood cell life span. Hemoglobin C trait (HbAC) is clinically silent. Hemoglobin C disease (HbCC) is also a mild disorder, and, while most people do not have any symptoms, others may experience mild hemolytic anemia, splenomegaly, and jaundice. Co-inheritance with HbS (HbCS) may cause severe complications, including vaso-occlusion crisis.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
