    Characterizing prostate cancer risk through multi-ancestry genome-wide discovery of 187 novel risk variants

    The transferability and clinical value of genetic risk scores (GRSs) across populations remain limited due to an imbalance in genetic studies across ancestrally diverse populations. Here we conducted a multi-a...

    Atlas of prostate cancer heritability in European and African-American men pinpoints tissue-specific regulation

    Although genome-wide association studies have identified over 100 risk loci that explain ∼33% of familial risk for prostate cancer (PrCa), their functional effects on risk remain largely unknown. Here we use g...
