TCF4 and endometriosis: Figure 2 shows an interatomic network involving fifteen regulatory proteins (SP1, FOXA1, FOXA2, P300, CFOS, GATA2, CTCF, RAD21, SMC3, CEBPB, HDAC2, MAFF, MAFK, RXRA, TCF4) whose potential binding sites were predicted in silico at the SNPs associated with endometriosis phenotypes and proxy SNPs (obtained using the STRING tool).
