• NM_000018.4:c.1843_1845delCGAinsAGG
• ACADVL p.616

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP7

The NM_000018.4(ACADVL):​c.1843_1845delCGAinsAGG​(p.616) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. The gene ACADVL is included in the ClinGen Criteria Specification Registry.

• Frequency: Genomes: not found (cov: 32)
• Consequence: ACADVL NM_000018.4 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.46

Genes affected

ACADVL (HGNC:92): (acyl-CoA dehydrogenase very long chain) The protein encoded by this gene is targeted to the inner mitochondrial membrane where it catalyzes the first step of the mitochondrial fatty acid beta-oxidation pathway. This acyl-Coenzyme A dehydrogenase is specific to long-chain and very-long-chain fatty acids. A deficiency in this gene product reduces myocardial fatty acid beta-oxidation and is associated with cardiomyopathy. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]
