Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4BP7

This summary comes from the ClinGen Evidence Repository: The c.1284G>A (p.Lys428=) variant (NM_000018.3) is a synonymous (silent) variant that is not predicted by NNSplice, MaxEntScan, and SpliceAI to impact splicing. In addition, it occurs at a nucleotide that is not conserved as shown by phyloP (BP4, BP7). The highest population minor allele frequency in gnomAD v4.1 is 0.001 in Non-Finnish European population (PM2_Supporting, BS1, and BA1 are not met). In summary, this variant meets the criteria to be classified as likely benign for autosomal recessive very long chain acyl-CoA dehydrogenase (VLCAD) deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen ACADVL Variant Curation Expert Panel: BP4, BP7 (ACADVL VCEP specifications version 1; approved November 9, 2021).

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]

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
