ABSTRACT Human microsomal and soluble epoxide hydrolases (mEH and sEH) are enzymes that metabolize xenobiotic molecules. We screened DNA from 48 Japanese individuals for single-nucleotide
polymorphisms (SNPs) in both genes by direct sequencing of the entire genomic regions containing _EPHX1_ and _EPHX2_, except for repetitive elements. This approach identified 33 SNPs in the
_EPHX1_ gene; 6 of them were located in the 5′ flanking region, 17 in introns, 8 in exons, and 2 in the 3′ flanking region. In the _EPHX2_ gene, we identified 36 SNPs, including 4 in the 5′
flanking region, 24 in introns, 5 in exons, and 3 in the 3′ flanking region, as well as one insertion/deletion polymorphism in the 5′ flanking region. These variants may contribute to a more
precise understanding of the nature of correlations between genotypes and disease-susceptibility phenotypes that have been postulated in regard to human microsomal and soluble epoxide
hydrolases. SIMILAR CONTENT BEING VIEWED BY OTHERS IDENTIFICATION, ANALYSIS OF DELETERIOUS SNPS OF THE HUMAN _GSR_ GENE AND THEIR EFFECTS ON THE STRUCTURE AND FUNCTIONS OF ASSOCIATED
