title: Five novel single nucleotide polymorphisms in the EPHX1 gene encoding microsomal epoxide hydrolase.
abstract: Five novel single nucleotide polymorphisms (SNPs) were found in the EPHX1 gene from 96 Japanese epileptic patients. The detected SNPs were as follows: 1) SNP, MPJ6_EX1009; GENE NAME, EPHX1 ACCESSION NUMBER, NT_004525.12; LENGTH, 25 bases; 5'-CCTCACTTCAGTG/ACTGGGCTTTGCC-3'. 2) SNP, MPJ6_EX1013; GENE NAME, EPHX1; ACCESSION NUMBER, NT_004525.12; LENGTH, 25 bases; 5'-TCCGCAGCCAGGG/CAGGACGACAGCA-3'. 3) SNP, MPJ6_EX1026; GENE NAME, EPHX1; ACCESSION NUMBER, NT_004525.12; LENGTH, 25 bases; 5'-GTTCTCCCTGGAC/TGACCTGCTGACC-3'. 4) SNP, MPJ6_EX1028; GENE NAME, EPHX1; ACCESSION NUMBER, NT_004525.12; LENGTH, 25 bases; 5'-AGGCAGGGGGACG/AGCCAGTCTTGGG-3'. 5) SNP, MPJ6_EX1030; GENE NAME, EPHX1; ACCESSION NUMBER, NT_004525.12; LENGTH, 25 bases; 5'-TGAAAAGTGGGTG/AAGGTTCAAGTAC-3'. The frequencies were 0.016 for MPJ6_EX1028 (IVS8+54G>A) and 0.005 for the other SNPs. The SNP MPJ6_EX1013 (130G>C) results in an amino acid alteration (E44Q). The other three SNPs in the coding region, MPJ6_EX1009 (30G>A), MPJ6_EX1026 (1056C>T), and MPJ6_EX1030 (1239G>A) result in synonymous changes (V10V, D352D, and V413V, respectively).
