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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 14 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.11764706 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.5, offset of 20, new splice context is: gagGTgtgg. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 19-43508773-A-C is Pathogenic according to our data. Variant chr19-43508773-A-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 577939.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
