For rs1859962 at 17q24, genotype dependent expression was observed for the candidate target gene SOX9 in TMPRSS2:ERG fusion-positive PrCa, which was not evident in TMPRSS2:ERG negative tumors.
We observed no association of the SNPs and the risk of developing PCa (OR 0.84, 95 % CI 0.30-2.38, p = 1.0 to rs1859962 and OR 1.94, 95 % CI 0.57-6.52, p = 0.28 to rs4430796), both sporadic and hereditary.
Genotype TG on 11q13 (rs7931342, T) could be related to an increased Gleason score, AG on HNF1B (rs4430796, A) could be associated with PSA increase, and TG on 17q24 (rs1859962, G) could be negatively associated with an increased BMI in Chinese men with PCa.
Furthermore, the SNPs rs6983561 and rs4430796 were associated with a susceptibility to aggressive prostate cancer, whereas rs1859962 was associated with non-aggressive prostate cancer.
Recent studies have identified 2 distinct genetic variants along chromosome 17, including allele T of single nucleotide polymorphism rs4430796 on 17q12 and allele G of single nucleotide polymorphism rs1859962 on 17q24, that have been linked to prostate cancer risk.
