Table 5 Frequencies for maternal alleles TLR2 (rs4696480) and TNFA-238

From: Ancestry informative markers and selected single nucleotide polymorphisms in immunoregulatory genes on preterm labor and preterm premature rupture of membranes: a case control study

  TLR2   TNFA-238
Mothers A T Mothers A G
Control (n = 201) 0.408ª 0.592 Control (n = 201) 0.065ª 0.935
PTL (n = 136) 0.423 0.577 PTL (n = 136) 0.044 0.956
PPROM (n = 63) 0.548b 0.452 PPROM (n = 64) 0.008b 0.992
  1. PTL preterm labor, PPROM preterm premature rupture of membranes. Data compared by Fisher’s exact test. In the comparison between groups, allelic frequencies followed by different letters (a, b) were statistically different. TLR2: Control x PPROM: p = 0.007; TNFA-238: Control x PPROM: p = 0.009
