Abstract

Eleven novel single nucleotide polymorphisms (SNPs) were found in the NR1I2 (PXR/SXR) gene from 205 Japanese subjects. The detected SNPs were as follows: 1) SNP, MPJ6_1I2001; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-TTTCTACCTCTAC/TTATTGAAAGGGC-3'. 2) SNP, MPJ6_1I2004; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-AGGCCCAAATGTG/AAGTGATGCATAG-3'. 3) SNP, MPJ6_1I2007; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-TGCCAGGCCTGCC/TGCCTGCGCAAGT-3'. 4) SNP, MPJ6_1I2008; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-GAGTGAGCAGTGG/CGCGCGCGGGCGG-3'. 5) SNP, MPJ6_1I2010; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-CAGAGGAGCAGCG/AGATGATGATCAG-3'. 6) SNP, MPJ6_1I2011; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-CTGGAAGTGGCCA/GGGAGGTTCAAAG-3'. 7) SNP, MPJ6_1I2013; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-TCTTCCTCTCGCC/TCCCAACTTCTGG-3'. 8) SNP, MPJ6_1I2017; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-ATTGAATGCAATC/TGGCCCCAGCCTG-3'. 9) SNP, MPJ6_1I2018; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-GGTGAGCACAGCA/GGGGGGTGAGGAC-3'. 10) SNP, MPJ6_1I2019; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-GAGCTCCGCAGCA/GTCAATGCTCAGC-3'. 11) SNP, MPJ6_1I2021; GENE NAME, NR1I2; ACCESSION NUMBER, AF364606; LENGTH, 25 bases; 5'-GGTGACACCTCCG/AAGAGGCAGCCAG-3'. The frequencies were 0.0293 for MPJ6_1I2021, 0.0073 for MPJ6_1I2011, and 0.0024 for the other 9 SNPs. All SNPs were found as heterozygous. Among these SNPs, MPJ6_1I2007, MPJ6_1I2010, MPJ6_1I2017 and MPJ6_1I2019 induce non-synonymous amino acid alterations (R98C, R148Q, R381W and I403V, respectively, in PAR1).
