We conducted a GWA meta-analysis of ∼7 million SNPs in 17,045 endometriosis cases and 191,596 controls, confirmed 9 out of 11 previously reported European risk loci, and identified five new genomic regions in or near CCDC170, SYNE1, FSHB, FN1 and 7p12.3 harbouring endometriosis risk loci. This evidence concerns the gene FN1 and endometriosis.
