ETFDH

Alias

ETF dehydrogenase; ETF-QO; ETF-ubiquinone oxidoreductase; ETFQO; MADD

Associated disorders

The ETFDH gene is associated with autosomal recessive multiple acyl-CoA dehydrogenase (MAD) deficiency (also known as glutaric acidemia type II; GA II) (MedGen UID: 75696).

The percentage of multiple acyl-CoA dehydrogenase deficiency that can be attributed to pathogenic variants in ETFDH is unknown.

The ETFDH gene encodes the enzyme Multiple Acyl-CoA dehydrogenase which is a component of the mitochondrial electron-transfer system essential for transferring eletrons from mitochondrial flavin-containing dehydrogenases to the main respiratory chain (PMID:25200064).

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
