[PMID 16352685] In Asian (Japanese) populations, the presence of an rs3087243(G) allele represents a 1.3 fold increased risk of autoimmune thyroid disease, and for those with autoimmune thyroid disease, a 1.5 fold increased risk of type-1 diabetes. However, in individuals without autoimmune thyroid disease, no association was seen between this SNP and type-1 diabetes. The authors speculate that earlier studies may have reported associations between this SNP and type-1 diabetes that were actually primarily based on the association with autoimmune thyroid disease.
This same SNP, rs3087243, has also been implicated as a (minor) risk factor for developing rheumatoid arthritis (RA). A study of 2,000+ European RA patients led to a calculated odds ratio of 1.13 (CI: 1.03 - 1.24) for the rs3087243(G) risk allele. [PMID 16380915]
In a different study involving recipients of liver transplants, although also with Spanish patients, the rs3087243(G) allele was significantly associated with acute rejection (odds ratio 1.49, p(corr)=0.038). Patients who lacked this allele had the lowest risk of acute rejection development. Allograft survival data did not show statistical differences between genotypes.[PMID 18047932]
