Eight novel single nucleotide polymorphisms in ABCG2/BCRP in Japanese cancer patients administered irinotacan.
Eight novel single nucleotide polymorphisms (SNPs) were found in the gene encoding the ATP-binding cassette transporter, ABCG2/BCRP, from 60 Japanese individuals administered the anti-cancer drug irinotecan. The detected SNPs were as follows: 1) SNP, MPJ6_AG2005 (IVS2-93T>C); Gene Name, ABCG2; Accession Number, NT_006204; 2) SNP, MPJ6_AG2007 (IVS3+71_72 insT); Gene Name, ABCG2; Accession Number, NT_006204; 3) SNP, MPJ6_AG2012 (IVS6-204C>T); Gene Name, ABCG2; Accession Number, NT_006204; 4) SNP, MPJ6_AG2015 (at nucleotide 1098G>A (exon 9) from the A of the translation initiation codon); Gene Name, ABCG2; Accession Number, NT_006204; 5) SNP, MPJ6_AG2017 (1291T>C (exon 11)); Gene Name, ABCG2; Accession Number, NT_006204; 6) SNP, MPJ6_AG2019 (IVS11-135G>A); Gene Name, ABCG2; Accession Number, NT_006204; 7) SNP, MPJ6_AG2020 (1465T>C (exon 12)); Gene Name, ABCG2; Accession Number, NT_006204; 8) SNP, MPJ6_AG2023 (IVS13+65T>G); Gene Name, ABCG2; Accession Number, NT_006204.MPJ6_AG2015 was a synonymous SNP (E366E). MPJ6_AG2017 and MPJ6_AG2020 resulted in amino acid alterations, F431L and F489L, respectively.
