For the IL-10 rs1800871, rs1800872, and rs1800896 genotype frequencies in the multiple sclerosis and healthy population groups, a Hardy–Weinberg analysis was performed to compare the observed and expected frequencies of the IL-10 rs1800871, rs1800872, and rs1800896 using the χ2 test in the control group. The gene discussed is IL10; the disease is multiple sclerosis.
