Interaction of parental KIR and fetal HLA-C genotypes with the risk of preeclampsia.

Objective: The aim of this study is to investigate whether certain combination of maternal killer cell immunoglobulin-like receptors (KIR) and fetal human leukocyte antigen-C (HLA-C) is risk for preeclampsia in the Chinese Han population.

Methods: A case-control study was conducted in 47 pregnant women with preeclampsia and 54 normal pregnant women. Twelve KIR genes were genotyped by PCR-sequence-specific primer in mothers.
