The ACADVL c.1405C>T; p.Arg469Trp variant (rs113994170), also known as Arg429Trp, has been reported in multiple individuals with VLCAD deficiency, including three severely affected individuals that were homozygous for the variant (Andresen 1999). Additionally, functional studies have shown that the variant protein has significantly reduced enzymatic activity (Goetzman 2007, Hoffmann 2012). This variant is reported in ClinVar (Variation ID: 21017), and observed in the general population with low overall allele frequencies of 0.008 percent (1/13006 alleles, Exome Variant Server), and 0.003 percent (7/246250 alleles, Genome Aggregation Database). The arginine at codon 469 is well conserved across species, and computational algorithms (SIFT, PolyPhen2, MutationTaster) predict this variant to be damaging to the protein. Taken together, this variant is considered pathogenic. REFERENCES Andresen BS et al. Clear correlation of genotype with disease phenotype in very-long-chain acyl-CoA dehydrogenase deficiency.
