Rs16856139 in SLC45A3, the same region as the previous Chinese study, showed an overall significant association with PSA levels (p=2.4×10(-11)) along with rs1058205 in KLK3.

Overall, we detected a genome-wide significant association between PSA levels and single-nucleotide polymorphisms (SNPs) at six loci: 5p15.33 (rs2736098), 10q11 (rs10993994), 10q26 (rs10788160), 12q24 (rs11067228), 17q12 (rs4430796), and 19q13.33 [rs17632542 (KLK3: I179T)], each with P(combined) <3 × 10(-10).

Previous research identified four single nucleotide polymorphisms (SNPs) principally associated with circulating PSA levels rather than with prostate cancer risk (TERT rs2736098, FGFR2 rs10788160, TBX3 rs11067228, KLK3 rs17632542).

When comparing prostate cancer cases with low PSA controls, alleles at genetic markers rs1512268, rs445114, rs10788160, rs11199874, rs17632542, rs266849, and rs2735839 were associated with an increased risk of prostate cancer, but the effect-estimates were attenuated to the null when using high PSA controls (Pheterogeneity in effect-estimates < 0.04).

The genotypes of 4 single nucleotide polymorphisms previously associated with serum prostate specific antigen levels (rs2736098, rs10788160, rs11067228 and rs17632542) were determined in 964 healthy Caucasian volunteers without prostate cancer.
The second locus was rs1354774 (P = 1.25 x 10(-12)), near KLK2 at 19q13, which was not associated with tPSA levels, and is separate from the rs17632542 locus at KLK3 that was previously associated with tPSA levels and prostate cancer risk.

We did not observe a strong association with the KLK3 variant, reported in previous studies to confer risk for prostate cancer (rs2735839; P = 0.20) but did observe three highly correlated SNPs (rs17632542, rs62113212 and rs62113214) associated with prostate cancer [P = 3.41 × 10(-4), per-allele trend odds ratio (OR) = 0.77, 95% CI = 0.67-0.89].

The overall results indicated that polymorphism T>C of rs1058</span>205 was associated with decreased risk of PCa</span> (allele contrast: OR = 0.75, 95% CI = 0.64-0.88, <i>P</i><sub>heterogeneity</sub> < 0.001; homozygote comparison: OR = 0.58, 95% CI = 0.42-0.81, <i>P</i><sub>heterogeneity</sub> < 0.001), particularly in Caucasian population (allele contrast: OR = 0.77, 95% CI = 0.65-0.91, <i>P</i><sub>heterogeneity</sub> < 0.001; homozygote comparison: OR = 0.58, 95% CI = 0.41-0.82, <i>P</i><sub>heterogeneity</sub> < 0.001).
