- Abstract
The results of studies on association between FCGR2A- R/H131 polymorphism and susceptibility to systemic lupus erythematosus (SLE) in the Asian population are controversial. To derive a more precise estimation on the genetic risk of FCGR2A- R/H131 variant for SLE in Asians, a meta-analysis was performed for genotypes R/R + R/H (dominant effect), R/R (recessive effect), and R allele in fixed/random effects models. Twenty studies involving 4,832 SLE patients and 6,190 controls were included. The meta-analysis showed that FCGR2A- R/H131 variant was associated with development of SLE in overall Asians both at allele or genotype level (R vs H, OR 1.201, 95 % CI 1.098-1.315; RR + RH vs HH, OR 1.369, 95 % CI 1.115-1.682; RR vs RH + HH, OR 1.305, 95 % CI 1.029-1.654). After stratification by ethnic, a significant association of R allele with susceptibility to SLE was observed in the Chinese population (R vs H, OR 1.104, 95 % CI 1.030-1.183). Evidence from subgroup analyses in non-Chinese populations (all Asians excluding Chinese population) also showed a significant association (R vs H, OR 1.354, 95 % CI 1.207-1.519; RR + RH vs HH, OR 1.705, 95 % CI 1.234-2.355). In addition, FCGR2A-R131 allele was associated with a 1.186-fold (95 % CI 1.043-1.349) greater risk for the occurrence of nephritis in the Asians population with SLE. After stratification by ethnic, this significant association was only consistently identified in non-Chinese populations (R vs H, OR 1.220, 95 % CI 1.002-1.486). In summary, FCGR2A- R/H131 polymorphism is associated with SLE and lupus nephritis in Asians.
