These data were generated to investigate the association and functional analysis of angiotensin-converting enzyme 2 genetic variants with the pathogenesis of pre-eclampsia(PE). This study conducted a case-control study involving 327 PE patients and 591 healthy pregnant women to explore the associations between candidate variants in the ACE2 gene  variants and the pathogenesis of PE.This study collected clinical samples and data, and used logistic regression, false positive report rate, multi factor dimension reduction, functional analysis and other analysis methods to process the research data. Potential functional ACE2 gene variants (rs2106809 A>G, rs6632677 G>C, and rs2074192 C>T) were selected and genotyped using kompetitive allele-specific PCR. The strength of the associations between the studied genetic variants and the risk of PE were evaluated using odds ratios (ORs) and corresponding 95% confidence intervals (CIs). Finally,it showed that the rs2106809 A>Gis significantly associated with the risk of PE via individual locus effects and/or complex gene-gene and gene-environment interactions.
