Human papillomavirus type 2c is identical to human papillomavirus type 27

Abstract

Human papillomavirus type 27 (HPV-27) and HPV-2c are isolates of the same virus as judged by genomic sequence identity. In a 400-bp stretch of the long control region and the E6 and L1 genes no changes were found between HPV-27 and HPV-2c whereas 55 changes were found between HPV-27 and HPV-2a. This justifies the elevation of HPV-2c to type status and strongly suggests its identity with HPV-27. This reassessment makes HPV-27 one of the most abundant viruses associated with common warts.
