Table 7 Haplotype frequencies for the TNFA in maternal samples

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

Mothers GG AG GA
Control (n = 201) 0.838 0.097 0.065a
PTL (n = 136) 0.812 0.154 0.033b
PPROM (n = 64) 0.875 0.094 0.031
  1. PTL preterm labor, PPROM preterm premature rupture of membranes. Data compared by Fisher’s exact test. In the comparison between groups, haplotype frequencies followed by different letters (a, b) were statistically different. Control x PTL: p < 0.001
