Results, however, were inconsistent: One study suggested that variants in AMACR gene were associated with familial, but not sporadic, prostate cancer [10] and other subsequent studies reported no association between sporadic prostate cancer and AMACR gene variants [18, 19] (http://dceg.cancer.gov/research/how-we-study/genomic-studies/cgems-summary/). This evidence concerns the gene AMACR and prostate cancer.
