title: Nested PCR approach for detection and typing of epidermodysplasia verruciformis-associated human papillomavirus types in cutaneous cancers from renal transplant recipients.
abstract: The epidermodysplasia verruciformis (EV)-associated human papillomaviruses (HPVs) constitute a group of HPV genotypes isolated mostly from the cutaneous lesions of patients with the genetic disorder of EV. Broad-spectrum detection of EV HPVs in cutaneous lesions of non-EV patients was previously difficult because no EV HPV consensus PCR was available. We describe a nested PCR that enables the detection of all known EV HPV types at relatively low-copy-number levels. The deduced sequences of a 92-amino-acid stretch of the L1 open reading frames of all types are shown for convenient typing. The technique proved very valuable in viral studies of skin cancers from renal transplant recipients. A high prevalence (81%) of EV HPV types was found in skin cancer biopsies. A wide spectrum of EV HPV types that differed from HPV-5 and -8 was found to be involved. The technique also proved useful in detecting potentially novel EV HPV types in skin cancers. The relationship of these new types to known HPV types is demonstrated by phylogenetic tree analysis.
