rs9623117

This study evaluated six microRNA processing machinery gene SNPs (rs3742330, rs14035, rs11077, rs9623117, rs197412, rs2740348) in 128 esophageal squamous cell carcinoma (ESCC) patients for associations with overall survival. The rs11077 AA genotype in XPO5 was independently associated with significantly increased 5-year survival (53.8% vs 18.2% for AC+CC carriers; relative risk 2.490, 95% CI 1.225-5.058, P=0.012), and the AA genotype correlated with high XPO5 expression levels.

A case-case association study of 18,343 prostate cancer patients (16,515 European, 1,828 African-American) evaluating 36 validated PC-risk SNPs found that rs2735839 (G allele) on chromosome 19q13 in the KLK3 gene was significantly and inversely associated with aggressive disease and high Gleason scores in both populations (p = 9.343 × 10⁻⁸ overall, p = 1.042 × 10⁻⁵ European, p = 2.0 × 10⁻⁴ African-American).

This meta-analysis of genome-wide association studies identified 30 prostate cancer risk-associated SNPs in Caucasian populations. The SNPs had odds ratios ranging from 1.12-1.47, except rs16901979 (OR=1.80). These 30 SNPs collectively explained approximately 13.5% of the total genetic variance in prostate cancer risk, with individual SNPs explaining 0.2-0.9% of variance.

This case-case study of 5,895 prostate cancer patients from Johns Hopkins Hospital examined 20 genome-wide association study (GWAS)-identified risk SNPs for association with clinicopathologic variables of cancer aggressiveness. Only rs2735839 in KLK3 (p = 8.4 × 10⁻⁷) and rs10993994 in MSMB (p = 0.046) showed significant associations, but notably with the risk alleles being more frequent in less aggressive rather than more aggressive disease, likely reflecting PSA detection bias. The vast majority of the 20 tested SNPs showed no association with Gleason score, tumor stage, or aggressive disease phenotypes, suggesting they identify overall prostate cancer risk rather than aggressiveness.
