Genome-wide association meta-analyses have identified variants in several genes, including SRP14, HOXB9, IFNG, GSTM1, WNT4, ICAM1, CYP17A1, PPARG, IL6, TGFB1, FSHR, TP53, TRA2A, VEZT/FGD9, and GREB1, demonstrating significant differences in expression potentially linked to endometriosis. Here, IL6 is linked to endometriosis.
