The genotype distributions of studied SNPs in both patients and controls complied with H-W equilibrium (p > 0.05). Statistical power of the present study, indicating the difference in the C1QB rs291982*G allele frequency between the patients and healthy controls for the odds ratio (OR) 2.5 reached 100%, for OR = 2.0 99.9%, while for OR = 1.2 was 38.8%.
