Characterization of a novel genital human papillomavirus by overlapping PCR: candHPV86 identified in cervicovaginal cells of a woman with cervical neoplasia

A novel human papillomavirus (HPV), candHPV86, was cloned and characterized from cervicovaginal cells obtained from a 37-year-old Hispanic woman with cervical intraepithelial neoplasia grade 1 (CIN1) using an overlapping PCR technique. Primers were designed by phylogenetic alignment of closely related HPV genomes using the L1 fragment sequence amplified by GP5+/6+. The 7983 bp complete nucleotide sequence of the HPV genome was determined by sequence walking. A basic local alignment sequence tool (BLAST) homology search using the L1 open reading frame demonstrated that this HPV was most closely related to HPVHAN2294 (GenBank, AJ400628; 86% homology) and HPV84 (84% homology). candHPV86 was placed in the HPV genome homology group A3 by phylogenetic analyses. The overlapping PCR technique is applicable for characterizing the complete spectrum and variation of HPVs in a population.
