Abstract Evidence has shown that pre‐eclampsia (PE) is associated with an increased level of catecholamines. Renalase is a catecholamine‐metabolizing enzyme, which contributes to the occurrence of hypertension. In the current study, we aimed to assess the relation between two renalase gene ( RNLS ) polymorphisms, including rs2576178 at the 5′‐flanking region and rs10887800 at intron 6, near the exon/intron border and PE susceptibility. In this case‐control study, 179 women with PE and 202 normotensive pregnant women were genotyped for RNLS rs2576178 and rs10887800 polymorphisms by the polymerase chain reaction‐restriction fragment length polymorphism method. There was no association between RNLS rs10887800 and rs2576178 polymorphisms and PE, neither in the dominant nor in the recessive model. Although there was no association between RNLS rs10887800 polymorphism and mild PE, this polymorphism was associated with 2.2‐fold higher risk of severe PE in the recessive model (odds ratio [OR], 2.2; 95% confidence interval [CI], 1.2‐4.4; P = 0.01) but not in the dominant model. The RNLS rs2576178 and rs10887800 polymorphisms were not associated with PE severity. The RNLS rs10887800 and rs2576178 GG/GG combined genotypes were associated with 8.4‐ and 16.7‐fold higher risk of PE and severe PE, respectively (OR, 8.4; 95% CI, 1‐71.1; P = 0.048 and OR, 16.7; 95% CI, 1.6‐167; P = 0.018). Also, the G‐G haplotype was associated with 1.7‐fold risk of PE and mild PE (OR, 1.7; 95% CI, 1.1‐2.4; P = 0.009 and OR, 1.7; 95% CI, 1.1‐2.5; P = 0.02). The RNLS rs10887800 polymorphism was associated with severe PE. The RNLS rs10887800 and rs2576178 GG/GG combined genotypes and G‐G haplotype were associated with higher risk of PE.
