FWIW, in trying to map normal blood types like O- or AB+ to the 47 (now 48 or 49) blood group systems, apparently that is only basically a value on the type 001 (ABO Group System) and type 004 (Rh group system). People could still have antigens that further bifurcate in the other 45+ blood group systems. So our ABO+/- system already doesn't have information on the other 45+ systems, and this new antigen wouldn't change that high level classification.
