Cervical Carcinogenesis and Immune Response Gene Polymorphisms: A Review

The local immune response is considered a key determinant in cervical carcinogenesis after persistent infection with oncogenic,high-risk human papillomavirus (hpv) infections. genetic variation in various immune response genes has been shown to influence risk of developing cervical cancer,as well as progression and survival among cervical cancer patients. we reviewed the literature on associations of immunogenetic single nucleotide polymorphism,allele,genotype,and haplotype distributions with risk and progression of cervical cancer. studies on hla and kir gene polymorphisms were excluded due to the abundance on literature on that subject. we show that multiple genes and loci are associated with variation in risk of cervical cancer. rather than one single gene being responsible for cervical carcinogenesis,we postulate that variations in the different immune response genes lead to subtle differences in the effectiveness of the antiviral and antitumour immune responses,ultimately leading to differences in risk of developing cervical cancer and progressive disease after hpv infection. © 2017 akash m. mehta et al.
