Association between human leukocyte antigen polymorphism and human papillomavirus 16-positive vulval intraepithelial neoplasia in British women.

Polymorphisms in human leukocyte antigen (HLA) genes have been implicated in the risk for developing human papillomavirus (HPV)-associated cervical neoplasia. By comparison with local cadaver controls typed for HLA class I (n = 946) and II (n = 144) antigens, HPV-16-positive high grade vulval intraepithelial neoplasia patients (n = 42) showed significantly different frequencies of HLA-A2 [odds ratio (OR), 2.1; confidence interval (CI), 1.

Human papillomavirus type 16 E6 variants in cervical carcinoma: relationship to host genetic factors and clinical parameters.

Infection with human papillomavirus type 16 (HPV-16) confers a high risk for the development of cervical neoplasia. Variants of this virus may interact differentially with host genetic factors, possibly altering the disease course. Thus, HPV-16 E6 variants may differ in their ability to degrade p53 whereas the polymorphic p53 alleles may provide more or less susceptible substrates for the viral oncogene product.
