The metanalysis of 11 GWAS of endometriosis has been performed in 2017 [41] and made it possible (through the mechanical increase in sample size: 191,596 controls and 17,045 endometriosis cases) to enrich the list of genes with five additional loci (FN1, CCDC170, ESR1, SYNE1 and FSHB), leading in 2017 to a list of 19 SNPs associated with the risk of endometriosis at the genome wide level (i.e. a p value below 5 × 10−8). The gene discussed is CCDC170; the disease is endometriosis.
