BACKGROUND. Telomerase activity is increased in most tumors. PinX1 has recently been identified as a critical component in regulating telomerase activity. The PinX1 gene is located within chromosomal region 8p22-23, a region associated with LOH and potentially linked to increased prostate cancer risk. METHODS. PINX1 was re-sequenced in 159 hereditary prostate cancer (HPC) probands. Four non-synonymous coding variants were genotyped in 159 HPC families. RESULTS. Thirty-nine polymorphisms were identified in the HPC screening panel. Ten coding polymorphisms were identified, seven (Gln 50His, Leu91Met, Gln206His, Arg 215Ile, Thr220Ala, Ser254Cys, and Glu 414Ala) of which were non-synonymous. The most common variants Thr220Ala and Ser254Cys were not significantly over-transmitted from affected parent to affected offspring. CONCLUSIONS. Based on these results, we conclude that PINX1 is not a major factor for HPC risk.
