HBD (Hemoglobin subunit delta) variants and mutations

The associated protein is Hemoglobin subunit delta. Delta-globin, a minor hemoglobin chain that contributes to the small adult hemoglobin A2 fraction. Like other globins, it participates in the hemoglobin complex that carries oxygen through the bloodstream. This CATVariant analysis covers 475 HBD variants and mutations. Disease context includes delta-beta-thalassemia; this analysis is associated with delta-beta-thalassemia. Available evidence includes missense variants, protein structure.
