The only other one I know anything about is the Bombay Phenotype, which is when you have blood cells that have no antigens on them at all. Even O- has the base receptors that all blood cells have (H antigen) but if you have Bombay Phenotype then you don't have those either. Idk what medical issues this causes but it definitely makes it extremely hard if not impossible to get blood if you need it because you would have to get blood from someone else with that rare mutation: there is no other alternative.
