Research Abstract	We examined the association between 30 SNPs identified by Genome-wide association study (GWAS) for prostate cancer (PC) and PC. We selected 16 SNPs for analysis except for 14 SNPs that were not useful. First, we determined a risk allele of each SNPs, and we analyzed the data based on an autosomal dominant model, next. In the univariate analysis, having ten or more risk genotypes in 16 SNPs significantly increased risk of PC. The odds ratio was 2.61 with sporadic cases, and 4.23 with familial cases. And in the ROC analysis, the areas under curves (AUCs) of these risk assessment models were 0.683 with SPC and 0.758 with FPC, respectively. This model could have a potential to diagnose PC, when it is applied to patients with family history of PC or not.
