Further Investigation in Europeans of Susceptibility Variants for Polycystic Ovary Syndrome Discovered in Genome-Wide Association Studies of Chinese Individuals

At least four of the PCOS susceptibility loci identified in the Chinese GWAS are associated with PCOS in Europeans. The overall genetic burden for PCOS, as demonstrated by the risk score, is also associated with the diagnosis of PCOS in Europeans. The PCOS susceptibility loci identified in the Chinese GWAS are thus likely to play an important role in the etiology of PCOS across ethnicities.
