MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the epoxide hydrolase family. The protein, found in both the cytosol and peroxisomes, binds to specific epoxides and converts them to the corresponding dihydrodiols. Mutations in this gene have been associated with familial hypercholesterolemia. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2012]
PHENOTYPE: Males homozygous for a targeted null mutation display a significant reduction in blood pressure both in the absence and presence of dietary salt loading. Both sexes exhibit altered arachidonic acid metabolism and reduced renal formation of epoxyeicosatrienoic and dihydroxyeicosatrienoic acids. [provided by MGI curators]
