HBB (Hemoglobin subunit beta) variants and mutations

The associated protein is Hemoglobin subunit beta. Beta-globin, one of the two major protein chains in adult hemoglobin. Hemoglobin uses these chains to transport oxygen from the lungs to tissues, and HBB variants are associated with sickle-cell disease and beta-thalassemia. This CATVariant analysis covers 775 HBB variants and mutations. Disease context includes sickle cell disease; this analysis is associated with sickle cell disease. Available evidence includes missense variants, protein structure.
