- Objective This study aimed to explore whether TYK2 polymorphisms are associated with susceptibility to autoimmune rheumatic diseases.
Methods We conducted a meta-analysis on the association between TYK2 polymorphisms and autoimmune rheumatic diseases.
Results Twelve studies with a total of 16,335 patients and 30,065 controls were included in the meta-analysis. Meta-analysis revealed an association between rheumatic diseases and the 2 allele of the TYK2 rs2304256 (OR=0.885, 95% CI=0.802-0.978, p=0.016). Furthermore, stratification by ethnicity identified a significant association between this polymorphism and rheumatic diseases in Caucasians (OR=0.822, 95% CI=0.706-0.889, p=9.5x10(-7)), but not in Asians (OR=1.127, 95% CI=0.835-1.522, p=0.434). Meta-analysis by rheumatic disease type revealed a significant association between the 2 allele of the TYK2 rs2304256 and SLE in Caucasians (OR=0.737, 95% CI=0.673-0.808, p˂1.0x10(-8)) but not in Asians (OR=1.211, 95% CI=0.813-1.804, p=0.347). Meta-analysis revealed that the rs12720356 polymorphism was associated with susceptibility to rheumatic diseases in Caucasians (OR=0.812, 95% CI=0.661-0.997, p=0.046) but not in Asians. Interestingly, the rs280519 polymorphism was significantly associated with susceptibility to SLE both in Caucasians and Asians. However, no associations were found between the rs12720270, rs280500, rs280523 and rs8108236 polymorphisms and susceptibility to rheumatic diseases.
Conclusions This meta-analysis demonstrates that the TYK2 rs2304256 and rs12720356 polymorphisms are associated with susceptibility to rheumatic diseases, rs2304256 polymorphism is associated with SLE in Caucasians, and rs280519 polymorphism is associated with SLE in Caucasians and Asians.
