rs1800871(C) carriers are associated with a reduced endometriosis risk by approximately 2x compared with the common rs1800871(T;T) genotype in a study of 196 Chinese patients. rs2222202 (C/T) (p=0.03) and rs1800871 (C/T) (p=0.05) showed significant allelic associations with pediatric onset Crohn's disease. rs1800871(T) carriers were 3x more likely to have their pregnancies terminate early (<10 weeks) than (C) carriers, based on a study of ~500 pregnancies. In a study of 1,757 cases of Alzheimer's disease and 6,295 controls, an interaction was replicated between IL6 genotype rs2069837(A;A) and IL10 genotype rs1800871(C;C). The synergy factor (SF) was 1.63 (CI: 1.10-2.41, p = 0.01), controlling for age, gender and ApoE4 genotype. 23andMe reports that each G allele at rs1800871 is associated with 0.6x lower odds of Behçet's disease.

Although rare for caucasians, normal for the asian population studied. The common TT genotype. increases a risk for endometriosis. Both the CT and the CC genotypes had a reduced risk for endometriosis by approximately 50% compared with the TT genotype.
