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]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 29, 2024This sequence change creates a premature translational stop signal (p.Arg41*) in the ETFDH gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ETFDH are known to be pathogenic (PMID: 16510302, 23785301). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individuals with glutaric acidemia type II (PMID: 12359134, 24190796). ClinVar contains an entry for this variant (Variation ID: 577047). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpSep 22, 2023Variant summary: ETFDH c.121C>T (p.Arg41X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 4e-06 in 251316 control chromosomes. c.121C>T has been reported in the literature in individuals affected with Glutaric Aciduria (e.g. Goodman_2002). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 12359134). Three submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

Pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesMay 03, 2024The ETFDH c.121C>T variant is predicted to result in premature protein termination (p.Arg41*). This variant has been reported in the compound heterozygous state in at least two individuals with glutaric acidemia type II (Goodman et al. 2002. PubMed ID: 12359134; Sahai et al 2013. PubMed ID: 24190796). This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
