dbSNP rs77484245: ETFDH:p.Asp511Glu (chr4-158706693-T-A) – ACMG Classification: Pathogenic (11 pts)

Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1PM2PM5PP2PP3_Strong

The NM_004453.4(ETFDH):c.1533T>A(p.Asp511Glu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,844 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D511N) has been classified as Likely pathogenic.

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 11 ACMG points.

PM1

In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_004453.4

PM2

Very rare variant in population databases, with high coverage;

PM5

Other missense variant is known to change same aminoacid residue: Variant chr4-158706691-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 194057.

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, 0.992
