It should be noted that other members of the ABC gene family, namely, ABCC3, ABCD1, and ABCD2, have been shown to confer chemoresistance in other cancer types, but, to our knowledge, we were the first to have reported an association of ABCD3 with prostate cancer [9] as well as with prostate cancer health disparity [9]. The gene discussed is ABCC3; the disease is prostate carcinoma.
