MIPOL1 and metastatic prostate carcinoma: To understand whether the mutation process extends downstream of the FOXA1 3′-UTR, we analyzed whole-genome sequencing data from the aforementioned cohort 10 metastatic prostate cancer patients and identified five somatic mutations in the 25 kb region between AL121790.1 TSS and FOXA1, and no mutations in the non-transcribed 11 kb region between MIPOL1 and the AL121790.1 (Supplementary Data 5).
