Eleven novel single nucleotide polymorphisms in the NR1I2 (PXR) gene, four of which induce non-synonymous amino acid alterations.

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).

Twelve novel single nucleotide polymorphisms in ABCB1/MDR1 among Japanese patients with ventricular tachycardia who were administered amiodarone.

Twelve novel single nucleotide polymorphisms (SNPs) were found in the gene encoding the ATP-binding cassette transporter, P-glycoprotein, from 60 Japanese individuals who were administered the anti-antiarrythmic drug, amiodarone. The detected SNPs were as follows: 1) SNP, MPJ6_AB1017 (IVS6-109); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 2) SNP, MPJ6_AB1018 (IVS7+14); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 3) SNP, MPJ6_AB1021 (IVS9-44); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 4) SNP, MPJ6_AB1052 (IVS12+17); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 5) SNP, MPJ6_AB1029 (IVS15-69); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 6) SNP, MPJ6_AB1040 (IVS24+16); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 7) SNP, MPJ6_AB1053 (IVS27-189); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 8) SNP, MPJ6_AB1054 (IVS27-172); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 9) SNP, MPJ6_AB1048 (IVS27-167); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 10) SNP, MPJ6_AB1055 (IVS27-152); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 11) SNP, MPJ6_AB1049 (IVS27-119); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168; 12) SNP, MPJ6_AB1051 (at nucleotide 3751 (exon 28) from the A of the translation initiation codon); GENE NAME, ABCB1; ACCESSION NUMBER, NT_017168. Among these SNPs, only MPJ6_AB1051 resulted in an amino acid alteration, V1251I.

[Reentrant tachyarrhythmia related to anatomic scar or isthmus].

Macroreentrant tachyarrhythmia rotating around an atrioventricular valve annulus or an atriotomy scar occurs after myocardial infarction or surgical repair of congenital heart disease. A 3D electroanatomic mapping can visualize the abnormal myocardium and the anatomical barrier which construct the isthmus of the reentrant circuit of figure-8, single-loop, or double loop morphology. Catheter ablation can eliminate most of tachycardias if the critical isthmus is precisely located by anatomic and entrainment mapping during tachycardia. Detailed potential and pace mapping during sinus rhythm is also helpful in identifying the optimal ablation site or the isthmus, when activation mapping is not available because of hemodynamically unstable or nonsustained tachycardia.
