FAS and nasopharyngeal carcinoma: FAS-AS1 SNP: In a cohort of 684 NPC and 823 control subjects, Guo et al. reported that individuals carrying the CC genotype of the FAS-AS1 SNP, rs6586163, were associated with reduced risk of NPC (CC vs. AA genotype, OR = 0.645, p = 0.006) and better OS (AC + CC vs. AA genotype, HR = 0.667, p = 0.030) compared to those with the AA genotype.
