Polymorphismi

Genetic variation in B3GALNT1 is responsible for the blood group P1PK system [MIMi:111400]. Different combinations or absence of the P1PK antigens define 5 different phenotypes: P1, P2, P1(k), P2(k), and P. The P1(k) and P2(k) phenotypes are rare and characterized by lack of the P antigen.
B3GALNT1 activity is responsible for the globoside blood group system (GLOB), which is defined by the P antigen [MIMi:615021].
