The adjustment of genotype profiles in TLR2 rs3804099, simultaneously by anemia and bleeding in ongoing pregnancy, and a threatened miscarriage or PTL, identified in previous pregnancies, also showed a relationship between TC heterozygotes and PTL in the over-dominant model (OR 0.51, 95% CI 0.30–0.88, p = 0.014, see Table 4). Here, TLR2 is linked to anemia (phenotype).
