Genes affected
ETHE1 (HGNC:23287): (ETHE1 persulfide dioxygenase) This gene encodes a member of the metallo beta-lactamase family of iron-containing proteins involved in the mitochondrial sulfide oxidation pathway. The encoded protein catalyzes the oxidation of a persulfide substrate to sulfite. Certain mutations in this gene cause ethylmalonic encephalopathy, an infantile metabolic disorder affecting the brain, gastrointestinal tract and peripheral vessels. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 27, 2023This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 185 of the ETHE1 protein (p.Leu185Arg). This variant is present in population databases (rs387906987, gnomAD 0.004%). This missense change has been observed in individual(s) with ethylmalonic encephalopathy (PMID: 14732903, 19289697, 20528888, 27830356). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 30725). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ETHE1 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
