The exhaustive study of Painter and coworkers [44] identified 13 loci associated together with endometriosis and endometrial cancer, with p < 10−4 (PTPRD, PDZRN3-CNTN3, SKAP1, KITLG-DUSP6, TFAP2D, KLF3-TLR10, LMO7-KCTD12, PARP11-CCND2, ZNF536-TSHZ3, THEM215-APTX, CEP112, WNT4-ZBTB40, PRIM2). This evidence concerns the gene ZBTB40 and endometriosis.
