The association between carrier status of TGFBR1*6A and prostate cancer in younger age group was significant after adjustment for race (OR 2.13, 95% CI 1.06–4.27) but was not significant after adjustment for race and age strata within groups (OR 2.11, 95% CI 0.98–4.57) (Table 2). This evidence concerns the gene TGFBR1 and prostate cancer.
