Scientists have found a single nucleotide polymorphism that occurs in about five per cent of African-American men making them at greater risk for developing prostate cancer. This research was supported by NIEHS and the National Cancer Institute.
The study examined about one million single nucleotide polymorphisms across the genomes of 3,425 African-American men with prostate cancer and 3,290 African-American controls. The study is part of the Multiethnic Cohort study being conducted in a collaborative effort between the Keck School and the University of Hawaii.
In general, men of African descent are more susceptible to prostate cancer than others. The current study reports the discovery of a prostate cancer marker on chromosome 17 and builds on a previous finding by the same research team which elucidated a marker on chromosome 8. These studies support the need for additional genome-wide association studies to locate markers which may play a role in understanding racial and ethnic health disparities.
