ID4 and endometriosis: For example, SNPs in 11 different loci located in or near IL1A (interleukin 1 alpha), ETAA (ETAA1 activator of ATR kinase), RND3 (Rho family GTPase 3), NFE2L3 (nuclear factor, erythroid 2 like 3), WNT4 (Wnt family member 4), ID4 (inhibitor of DNA binding 4), CDKN2B-AS1 (cyclin-dependent kinase inhibitor 2B antisense RNA), VEZT (vezatin, adherens junctions transmembrane protein), GREB1 (growth regulating estrogen receptor binding 1), and FN1 (fibronectin 1) are correlated with the risk of endometriosis [17].
