EPHX1（epoxide hydrolase 1），癌症关联基因，基因ID：2052，环氧化物水解酶是一种重要的生物转化酶，它将环氧化物从芳香族化合物的降解转化为可从体内结合和排出的反式异构体。环氧水解酶在环氧化物的活化和解毒中起作用。该基因的突变导致子痫前期、环氧水解酶缺乏或环氧酶水解酶活性增加。另一种编码相同蛋白质的剪接转录变体已被发现用于该基因。[由RefSeq提供，2008年12月]Epoxide hydrolase is a critical biotransformation enzyme that converts epoxides from the degradation of aromatic compounds to trans-dihydrodiols which can be conjugated and excreted from the body. Epoxide hydrolase functions in both the activation and detoxification of epoxides. Mutations in this gene cause preeclampsia， epoxide hydrolase deficiency or increased epoxide hydrolase activity. Alternatively spliced transcript variants encoding the same protein have been found for this gene.[provided by RefSeq， Dec 2008]。
