Notes

IL23R gene SNP, part of a haplotype with rs11209026 associated with psoriasis. In a study of 216 North American patients with Graves' disease, the homozygous rs10889677(T;T) genotype was significantly associated with Graves' disease but not specifically with Graves ophthalmopathy; the odds ratio was 9.4 (p=0.02).
