Abstract
BACKGROUND: Renalase is a novel enzyme that degrades circulating catecholamines. We aimed to investigate the role of rs2576178 and rs10887800 polymorphisms of the renalase gene in preeclampsia (PE) patients METHODS: This case-control study consisted of 110 women with PE and 102 normotensive controls. PCR-RFLP method was used for determination of renalase gene polymorphisms. RESULTS: Allele frequency and genotype distribution of rs10887800 polymorphism were found statistically significantly higher in women with PE (p<0.05). Also G allele and GG genotype of rs10887800 polymorphism were found higher in women with severe PE than that of mild PE (p<0.05). There was no significant difference for rs2576178 polymorphism in terms of allele frequency and genotype distribution (p>0.05). In PE patients, systolic blood pressure (SBP) means according to rs10887800 genotypes were found statistically significantly higher (GG vs AA; p=0.001) and (GG vs GA; p=0.001). Similarly, diastolic blood pressure (DBP) means were found statistically significantly higher in PE patients (GG vs GA: p=0.001); (GG vs AA: p=0.004). For rs2576178 polymorphism, SBP means were found as (GG vs AA; p=0.012, GG vs GA; p>0.05) in PE patients. DBP means were not significant according to rs2576178 genotypes in PE patients (p>0.05). CONCLUSIONS: The findings of the present study suggest that blood pressure may be increased by GG genotype and G allele of rs10887800 polymorphism and the polymorphism may increase the susceptibility to PE.
