HLA class II susceptibility to cervical cancer among Tunisian women.

The variability in host immunogenetic background, especially in human major histocompatibilty genes, has been shown to influence the susceptibility to human papillomavirus (HPV) infection and cervical neoplasia. Here, we conducted a case-control study in Tunisian women to examine the effect of genetic variation in HLA class II DRB1 and DQB1 genes on invasive cervical cancer (ICC) and squamous cell carcinoma (SCC). HLA genotyping was performed by PCR sequence-specific primers technique.
