title: Three novel single nucleotide polymorphisms in UGT1A10.
abstract: Three novel single nucleotide polymorphisms (SNPs) were found in the UDP-glucuronosyltransferase (UGT) 1A10 gene from 24 Japanese patients with various cancers who were administered the anti-tumor drug, irinotecan (CPT-11). The detected SNPs were as follows: 1) SNP, MPJ6_U1A003; GENE NAME, UGT1A10; ACCESSION NUMBER, AF297093; LENGTH, 25 bases; 5'-CAGATGCCATGAC/TTTTCAAGGAGAG-3'. 2) SNP, MPJ6_U1A004; GENE NAME, UGT1A10; ACCESSION NUMBER, AF297093; LENGTH, 25 bases; 5'-CCTAGAAATAGCC/TTCTGAAATTCTC-3'. 3) SNP, MPJ6_U1A030; GENE NAME, UGT1A10; ACCESSION NUMBER, AF297093; LENGTH, 25 bases; 5'-GGTTGTAGTCATG/ACCAGAGGTGAGT-3' All the three SNPs were located in exon 1 and their frequencies were all 0.021. Among these SNPs, MPJ6_U1A003 and U1A030 resulted in amino acid alterations, T202I and M59I, respectively. The third SNP, MPJ6_U1A004, introduced a synonymous amino acid change (A231A).
