A previous genome-wide association study of polycystic ovary syndrome (PCOS) identified several susceptibility loci. TOX3 is the nearest gene to signal rs4784165. In the present study, all exons and exon-intron boundaries of TOX3 were amplified and sequenced in 200 Chinese women with PCOS. A 3-bp nucleotide deletion of CAG repeat and two known single nucleotide polymorphisms were identified. No plausible pathogenic mutations were detected. The results suggest that mutations in TOX3 are not common in Chinese Han women with PCOS.
