BGLAP and ovarian cancer: We perform an epigenome-wide DNAme analysis in cervical smear samples from women who were subsequently diagnosed with ovarian cancer, and in matched controls (i.e. the Discovery Set), and establish/validate the WID-OC-index (Women’s risk IDentification for Ovarian Cancer index) which we then further validate in an independent set of cervical samples (i.e. External Validation Set).
