Item Genome-wide association study of prostate cancer in men of African ancestry identifies a susceptibility locus at 17q21.(2011-05-22) Haiman, C. A.; Chen, G. K.; Tettey, Y.; Strom, S.

We followed up the most significant 17 new associations from stage 1 in 1,844 cases and 3,269 controls of African ancestry. We identified a new risk variant on chromosome 17q21 (rs7210100, odds ratio per allele = 1.51, P = 3.4 × 10(-13)). The frequency of the risk allele is ∼5% in men of African descent, whereas it is rare in other populations (<1%). Further studies are needed to investigate the biological contribution of this allele to prostate cancer risk. These findings emphasize the importance of conducting genome-wide association studies in diverse populations.
