Abstract

Objective: NODAL has been implicated in timing of parturition and immune regulation. We investigated the relationship between NODAL polymorphisms, infection/inflammation, and preterm birth.

Study Design: For this secondary analysis, 613 women (189 preterm and 424 term) from the Montreal Prematurity Study were genotyped for NODAL polymorphisms and assessed for bacterial vaginosis and placental inflammation.

Result: NODAL polymorphisms were not associated with preterm birth. However, the rs2231947(C>T) variant allele was associated with increased risk for preterm birth among women with bacterial vaginosis (odds ratio: 2.76, 95% confidence interval: 1.12-6.85). Among women without placental inflammation, the rs1904589(A>G) variant allele was associated with increased risk of preterm birth (odds ratio: 1.31, 95% confidence interval: 1.02-1.70). Among women with placental inflammation, the rs10999338(C>T) variant allele was associated with reduced risk of preterm birth (odds ratio: 0.50, 95% confidence interval: 0.29-0.87).

Conclusion: The effect of NODAL polymorphisms on preterm birth depends on maternal infection/inflammation status.
