Of the regions/genes found to be important, the association was primarily with HPV persistence for GTF2H4 and SULF1. IFNG and the epidermodysplasia verruciformis (EV)-associated genes (TMC6-EVER1 and TMC8-EVER2) were primarily associated with progression to CIN3/cancer. This evidence concerns the gene IFNG and epidermodysplasia verruciformis.
