Important examples of genes with concurrent findings in both studies are the HOXA gene cluster, members of the GATA family of TFs (GATA2, GATA4 and GATA6), and TBX3, which encode transcription factors (TFs) that specify cellular identities in development, NR5A1, coding for a TF that plays a role in endometriosis by deregulating steroid signaling [73, 74], and DAPK1, encoding a protein kinase that regulates cell survival and apoptosis [75]. The gene discussed is GATA4; the disease is endometriosis.
