Genetic Predictors of PSA Levels Could Boost Reliability of PSA Tests to Diagnose Prostate Cancer

Genetic Predictors of PSA Levels Could Boost Reliability of PSA Tests to Diagnose Prostate Cancer
Unravelling genetic predictors that determine a man's natural PSA levels could help enhance the sensitivity and specificity of PSA tests as a tool for diagnosing prostate cancer, according to a recent study. Researchers at the University of California San Francisco (UCSF) were able to identify genetic variations that explain up to 41 percent of PSA variation, suggesting that this  information could aid in improving prostate cancer screening. The study, "Genome-wide association study of prostate-specific antigen levels identifies novel loci independent of prostate cancer," appeared in Nature
