Sickle-cell disease, or SCD, is a hereditary (genetic) aberrancy among Africans and people of African descent. About one in 500 Afro-Americans have the condition. Normal hemoglobin, which is essential for oxygen transport via the red blood cells, is coded for by 2 hemoglobin-A genes, so normals are AA.
