Chi-squared test with 95% confidence interval identified two genes in the set of studied genes, whose SNP allele and genotype frequency difference in women with miscarriage and control group is statistically significant—TLR9 (p < 0.0001 for both multiplicative and additive models of inheritance) (Tables 5 and 6) and IL-10 (p=0.0003 for multiplicative model of inheritance and p=0.001 for additive model of inheritance) (Tables 15 and 16). Here, TLR9 is linked to spontaneous abortion.
