Abstract:
OBJECTIVE:To assess the association of apolipoprotein (apo) C1 (APOC1) gene rs4420638A/G and -317H1/H2 polymorphisms with the risk of pre-eclampsia (PE) and the influence of their genotypes on the clinical and metabolic indexes among Chinese women.
METHODS:In total 289 PE patients and 824 women with uncomplicated pregnancies were included. The rs4420638A/G genotype was determined by a Taqman real-time PCR allelic discrimination assay. The -317H1/H2 genotype was measured through PCR and restriction fragment length polymorphism analysis. Serum lipid and apo levels were measured by an enzymatic kit and a PEG-enhanced immunoturbidimetric assay.
RESULTS:Allelic and genotypic frequencies of the APOC1 gene rs4420638A/G and -317H1/H2 were not significantly different between the two groups (all P> 0.05). However, patients carrying the G allele of the rs4420638A/G locus had higher serum levels of triglyceride, non-HDL-C and apoB, and a higher apoB/apoA1 ratio compared with those with an AA genotype (all P< 0.05). Patients carrying the H2 allele of the -317H1/H2 polymorphism had smaller delivery gestational weeks compared with those with the H1H1 genotype (P< 0.05).
CONCLUSION:Polymorphisms of the APOC1 gene rs4420638 and -317H1/H2 sites may be associated with abnormal lipoprotein metabolism among Chinese patients with PE, though no association was found between variants of the APOC1 gene and the risk of PE among them.
