Genes affected

ETFDH (HGNC:3483): (electron transfer flavoprotein dehydrogenase) This gene encodes a component of the electron-transfer system in mitochondria and is essential for electron transfer from a number of mitochondrial flavin-containing dehydrogenases to the main respiratory chain. Mutations in this gene are associated with glutaric acidemia. Alternatively spliced transcript variants that encode distinct isoforms have been observed. [provided by RefSeq, Aug 2013]

ETFDH Gene-Disease associations (from GenCC):

multiple acyl-CoA dehydrogenase deficiency

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 17 ACMG points.

PM1

In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_004453.4

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 86 curated pathogenic missense variants (we use a threshold of 10). The gene has 11 curated benign missense variants. Gene score misZ: 0.39306 (below the threshold of 3.09). Trascript score misZ: 0.49505 (below the threshold of 3.09). GenCC associations: The gene is linked to multiple acyl-CoA dehydrogenase deficiency.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.971

PP5

Variant 4-158699098-G-A is Pathogenic according to our data. Variant chr4-158699098-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 459962.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
