How Cancer Risk SNPs May Contribute to Prostate Cancer Disparities.

Disparities in cancer incidence, prevalence, burden, and outcome exist among specific population groups in the United States. Researchers have identified germline genetic risk single-nucleotide polymorphisms (SNP) that differ by ancestry and may contribute to some of these differences. In this issue of , Han and colleagues found the prostate cancer risk SNP rs4713266 is associated with increased risk of patients with African ancestry.
