Genes affected
EPHX2 (HGNC:3402): (epoxide hydrolase 2) 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.524C>A (p.A175D) alteration is located in exon 4 (coding exon 4) of the EPHX2 gene. This alteration results from a C to A substitution at nucleotide position 524, causing the alanine (A) at amino acid position 175 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
