Description

The NM_000018.4(ACADVL):c.622+12C>A variant in ACADVL is an intronic variant which is located in intron 7. The highest population minor allele frequency in gnomAD v2.1.1 is 0.0027 in South Asian population. The results from two in silico splicing predictors (SpliceSiteFinder-like and NNSPLICE) support that this variant does not affect splicing (BP4). Due to limited evidence, this variant is classified as a variant of unknown significance for autosomal recessive very long chain acyl CoA dehydrogenase (VLCAD) deficiency based on ACMG/AMP criteria applied, as specified by the ClinGen ACADVL Variant Curation Expert Panel: BP4.
