BackgroundCervical cancer is one of the most important cancers in African women. Polymorphisms in the Fas FasR and Fas ligand FasL genes have been reported to be associated with cervical cancer in certain populations. This study investigated whether these polymorphisms are associated with cervical cancer or human papillomavirus HPV infection in South African women.

FindingsParticipants were 447 women with invasive cervical cancer 106 black African and 341 women of mixed-ancestry and 424 healthy women controls, matched by age, 101 black African and 323 women of mixed-ancestry and domicile rural or urban. Two polymorphisms in Fas gene FasR-1377G-A, FasR-670A-G and one in FasL gene FasL844T-C were genotyped by TaqMan. None of the polymorphisms, or the Fas haplotypes, showed a significant association with cervical cancer. There was also no association with HPV infection in the control group. However, on analysis of the control group, highly significant allele, genotype and haplotype differences were found between the two ethnic groups. There were generally low frequencies of FasR-1377A alleles, FasR-670A alleles and FasL-844C alleles in black women compared to the women of mixed-ancestry.

ConclusionThis is the first study on the role of Fas and FasL polymorphisms in cervical cancer in African populations. Our results suggest that these SNPs are not associated with cervical cancer in these populations. The allele frequencies of the three SNPs differed markedly between the indigenous African black and mixed-ancestry populations.
