WebApr 29, 2024 · Most red blood cell antigens are synthesized by the red blood cells but some blood group antigens, such as those of the Lewis and Chido/Rogers systems are adsorbed onto the red cell surface membrane from the plasma. Some red cell antigens are specific only to red cells while others are found on other cells throughout the body. For a long time, the origin of RHD polymorphism was an evolutionary enigma. Before the advent of modern medicine, the carriers of the rarer allele (e.g. RhD-negative women in a population of RhD positives or RhD-positive men in a population of RhD negatives) were at a disadvantage as some of their children (RhD-positive children born to preimmunised RhD-negative mothers) were at a higher risk of fetal or newborn death or health impairment from hemolytic disease.
