Abstract [en]

Cervical cancer (CxCa) is caused by persistent human papillomavirus (HPV) infection; genetic predisposition is also suspected to play a role. Our study is a targeted candidate gene follow-up based on: (i) strong clinical evidence demonstrating that mutations in the TMC6 and TMC8 (EVER1 and EVER2) genes associate with the HPV-associated disease epidermodysplasia verruciformis (EV) and (ii) recent epidemiological data suggesting a genetic susceptibility conferred by polymorphisms in such genes for skin and CxCa. Clarifying the association of the TMC6/8 genes with risk of CxCa will help in understanding why some HPV-infected women develop persistent infection, cervical lesions and eventually cancer while others do not. Twenty-two single nucleotide polymorphisms (SNPs) harboring the TMC6/8 genes were genotyped in 2,989 cases with cervical intraepithelial neoplasia grade III or invasive CxCa and 2,281 controls from the Swedish population. Association was evaluated in logistic regression models. Two SNPs displayed association with cervical disease: rs2290907 [odds ratio (OR)(GGvsAA) = 0.6, 95% confidence interval (95% CI): 0.3-0.9, p = 0.02)] and rs16970849 (OR(AGvsGG) = 0.8, 95% CI: 0.66-0.98, p = 0.03). The present data support the involvement of the TMC6/8 region in CxCa susceptibility but further analyses are needed to replicate our findings, fully characterize the region and understand the function of the genetic variants involved.

Abstract [en]

Cervical cancer is the forth most commonly diagnosed cancer among women worldwide. It is caused by persistent infection with an oncogenic type of Human Papillomavirus (HPV). The HPV is a necessary but not sufficient cause of cervical cancer. Environmental factors such as smoking, high parity and long-term use of oral contraceptives increases the risk of cervical cancer. Genetic factors also affect the risk of developing the disease. The aim of this thesis is to search for and evaluate genetic risk factors for cervical cancer using both a candidate gene approach and a genome-wide association study (GWAS).

Paper I examined the association of genetic variation in three Fanconi Anemia (FA) genes (FANCA, FANCC and FANCL), involved in DNA repair, with cervical cancer susceptibility in the Swedish population. No association was observed. Paper II evaluated the association of genetic variation in the TMC6 and TMC8 genes with susceptibility to cervical cancer in the Swedish population and an association of two SNPs (rs2290907 and rs16970849) with cervical cancer was observed.  In paper III the first GWAS performed in cervical cancer was reported. Three independent loci in the major histocompatibility complex (MHC) region at 6p21.3 were found to affect the susceptibility to cervical cancer. Paper IV examined the sequence variation in the TMC6 and TMC8 region and its association with cervical cancer. A highly polymorphic 21 bp sequence was identified and found to be repeated 5 to 42 times in both cases and controls. Lack of this repeat was associated with increased risk of cervical cancer. An intronic SNP (rs2926778) located in between the TNRC6C and TMC6 genes was also found to be associated with cervical cancer.

The thesis provides evidence for the importance of genes in the immune system for cervical cancer susceptibility. The genetic risk factors identified explain only a part of the genetic susceptibility, implying that other risk factors remains to be identified
