3 Antigens P k & P are on different cells. Antigen P1 is only on RBC. P k Ag is the precursor of P Ag. The gene of P k is on chromosome 22. It produts Galactosil Transferase. The gene of P is on chromosome 3.

4 Major Phenotypes: P1,P2 Some of person who has P2 Ag nuturaly has Anti P1 Anti PBiphasic Donath LandstainerPCH (Paroxysmal Cold Hemoglobinuria)
