    Abstract

    Purpose: There is a growing association of human papillomavirus (HPV) with some cases of mucosal squamous cell carcinoma of the head and neck (HNSCC), particularly of the oropharynx. Persistent oral HPV infection is believed to increase the likelihood of malignancy, and it is possible that host genetic factors can determine susceptibility to persistent HPV infection. Polymorphisms in the two EV genes (EVER1 and EVER2, also known as transmembrane channel protein (TMC) 6 and 8) have been identified as strong candidate genes, since a small number of critical mutations in these genes have been shown to cause profound and florid skin HPV infections, and some of them have been linked to susceptibility to cervical cancer. Methods: We sought to determine whether there was a difference in the frequency of single nucleotide polymorphisms (SNPs) in EVER1 (rs2613516, rs12449858) and EVER2 (rs7205422, rs12452890) between HNSCC patients with HPV-positive and HPV-negative tumors, and healthy controls. We used logistic regression to analyze SNPs in 219 patients with histologically confirmed primary SCC of the oropharynx, oral cavity, hypopharynx, or larynx, and 321 healthy controls. Results: We did not find any associations with the EVER1/EVER2 SNPs and HPV status or being a HNSCC case or a control. Conclusions: The present data do not provide evidence for a role of genetic variations in EVER1 or EVER2 for HPV status of mucosal HNSCC or between HNSCC patients and controls.
