Thus, several of its SNPs, including the rs7586110 (UGT1A7*12_c.-57T>G) (MAF = 0.417) and rs8175347 (UGT1A1*28_c.TATA-box) (MAF = 0.271), have been previously linked to different types of diseases, including cancer, cardiovascular diseases, and irinotecan toxicity in patients with Gilbert's syndrome, to name a few [50–53]. This evidence concerns the gene UGT1A1 and cancer.
