ObjectiveTo assess the association of TLR4 (rs4986790 and rs4986791) and TNF- (rs1800629) genes polymorphisms and TLR4mRNA levels with preterm birth.MethodsHospital-based case-control study on women of Caucasoid morphological subtype ethnicity in Northern India. Inclusion criteria for cases: women aged between 18-40 years with preterm birth (<37 weeks gestation), and for controls: women who delivered a term neonate consecutive to an enrolled case. Three polymorphisms TLR4 (Asp299 Gly, Thr399 Ill) and TNF-a (-308G/A) and TLR4 mRNA levels were compared between cases and controls.ResultsFrom 2012-2015, 559 cases and 559 controls were recruited. TLR4 mRNA levels were found to be higher (P<0.001) in cases [(0.7 (0.04)] than in controls [(0.5 (0.04)]. No association was found between TLR4 Asp299 Gly, TLR4 Thr399 Ill and TNF- (-308G/A) with preterm birth.ConclusionIncreased TLR4 mRNA levels seem to be associated with preterm birth, and can be investigated further as a potential biomarker for identifying women at risk.
