In the original version of this Article the genetic locus 8p23.1 was incorrectly referred to as 8p32.1 throughout. For example, in the Abstract, the sentence beginning ‘Three loci reach genome-wide significance in the case-control meta-analysis…' originally read ‘Three loci reach genome-wide significance in the case-control meta-analysis, two novel loci mapping to chr 8p32.1 and chr 11p14.1, and a chr 9q22.32 locus previously found in Chinese PCOS'. Each occurrence of this error has now been corrected in both the PDF and HTML versions of the Article.
