he P1 blood group antigen is a glycosphingo-

Tlipidl which is dominantly inherited. On the basis

of the current structural data, there are two sets of

alleles, one which adds the P1 -specific sugar and the

other which does not. Therefore, two phenotypes,

Pl positive and P1 negative (or the P2 phenotype)

are possible. About 20 percent of the white population

is PI negative, and the serum of those individuals

may contain anti-P1 antibodies.
