In a case-control study including 550 CRC patients and 540 controls, longer CAG repeats in the androgen receptor gene (AR) that reduce the transcription rates, have been associated with higher CRC risk and lower 5-year median overall survival (hazard ratio of 1.4 [95% CI, 1.04–1.79]) in CRC patients (57). Here, AR is linked to colorectal carcinoma.
