For example, the UCEC tumor (TCGA-D1-A17Q-01A-11D-A12J-09) had the largest number of mutations in UGT genes among UCEC tumors, including one mutation in each of eleven different UGT genes (1A3, 1A4, 2A1, 2A2, 2B4, 2B7, 2B11, 2B15, 2B17, 3A1 and 3A2), three mutations in UGT8, and four mutations in UGT2B28 (Table S3). The gene discussed is SLC35A2; the disease is neoplasm.
