Objective: Mannose-binding lectin (MBL) is a serum lectin that mediates phagocytosis and activates complement. We investigated the association of mbl-2 functional polymorphisms with human papillomavirus (HPV) infection, which is a primary etiologic factor for cervical cancer.
Study design: The frequencies of haplotypes and genotypes of mbl-2 exon1 and promoter region variants were analyzed in 150 patients with HPV and 277 control subjects with no HPV. Unconditional logistic regression analysis was performed to evaluate an association between specific mbl-2 alleles and susceptibility to HPV infection.
Results: The frequency of high-producer mbl-2 genotypes was higher in patients with HPV than in control subjects with no HPV (P = .001). The genotype of the mbl-2 gene polymorphisms represented the least significant risk for the group with HPV.
Conclusion: Certain polymorphisms in the MBL promoter region are increased among cervical samples that demonstrate HPV infection. This finding suggests a potential link between MBL and high-risk HPV infection.
