The present study investigated the disruption of E1, E2 genes in a total of eighty four HPV16\u2010positive precancerous and cervical cancer specimens derived from Greek women (seventeen paraffin\u2010embedded cervical biopsies and sixty seven Thin Prep samples). Complete E2 and E1 genes were amplified using three and nine overlapping primer sets respectively, in order to define the sites of disruption. Extensive mapping analysis revealed that disruption\/deletion events within E2 gene occurred in high grade and cervical cancer samples (x<jats:sup>2<\/jats:sup> test, <jats:italic>P\u2009<\/jats:italic>&lt;\u20090.01), while no evidence of E2 gene disruption was documented among low grade cervical intraepithelial neoplasias. In addition, disruptions within the E1 gene occur both in high and low grade cervical intraepithelial neoplasia. This leads to the assumption that in low grade cervical intraepithelial neoplasias only E1 gene disruption was involved (Fisher's exact test, <jats:italic>P\u2009<\/jats:italic>&lt;\u20090.05), while in high grade malignancies and cervical cancer cases deletions in both E1 and E2 genes occurred. Furthermore, the most prevalent site of disruption of E1 gene was located between nucleotides 1059 and 1323, while the most prevalent deleted region of the E2 gene was located between nucleotides 3172 and 3649 (E2 hinge region). Therefore, it is proposed that each population has its own profile of frequencies and sites of disruptions and extensive mapping analysis of E1 and E2 genes is mandatory in order to determine suitable markers for HPV16 DNA integration analysis in distinct populations. <jats:bold><jats:italic>J.
