Meta-analysis of two Chinese populations identifies an autoimmune disease risk allele in 22q11.21 as associated with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a heterogeneous disease with a diverse spectrum of clinical symptoms, ranging from skin rash to end-organ damage. 22q11.21 has been identified as a susceptibility region for several autoimmune diseases, including SLE. However, detailed information for SLE association and the underlying functional mechanism(s) is still lacking. Through meta-analysis of two genome-wide association studies (GWAS) on Han Chinese populations, comprising a total of 1,659 cases and 3,398 controls matched geographically, we closely examined the 22q11.21 region, especially on the r...
