Distribution of haptoglobin genotypes

GenotypeTotal (n=109)Pre-eclampsia (n=25)PE + HELLP (n=84)Controls (n=166)
Percentages are given in parentheses.
Genotypes: Hp1-1: both alleles encoding for α1. Hp1-2: one allele encoding for α1 and the other for α2. Hp2-2: both alleles encoding for α2. Hp0-0: no amplification of one of the alleles.
