Interaction between ABO and Haptoglobin in a White Australian Population

Abstract
Blood samples from over 2,200 blood donors resident in the State of Victoria were investigated for the association between the ABO and haptoglobin (HP) blood systems reported by others. No association between the phenotypes of the 2 systems was found but the distribution of the HP*1 allele varied among ABO groups, and the difference between those who were group 0 and the other ABO groups combined was significant (p < 0.05). Overall, the findings were similar, but not as pronounced, as those reported in the Hutterites.
