Figure 4From: Two previously proposed P1/P2-differentiating and nine novel polymorphisms at the A4GALT (Pk) locus do not correlate with the presence of the P1 blood group antigenSchematic representation of the primers used to identify the polymorphisms at -551_-550insC and -160A>T, described to cause the P 2 phenotype. The figure also shows combinations and positions for the primers used to detect a linkage phase of SNPs in the reading frame with a polymorphism in the 3'-UTR.
