There was significant enrichment of ESR1 binding present in multiple datasets near genomic regions associated with breast cancer (7.45-fold, p = 0.001), height (2.45-fold, p = 0.002), multiple sclerosis (5.97-fold, p < 0.0002) and prostate cancer (4.47-fold, p = 0.0008), and suggestive evidence of ESR1 enrichment for regions associated with coronary artery disease, ovarian cancer, Parkinson’s disease, polycystic ovarian syndrome and testicular cancer. The gene discussed is ESR1; the disease is prostate cancer.
