Variant summary: ACADM c.320T>C (p.Leu107Ser) results in a non-conservative amino acid change located in the Acyl-CoA dehydrogenase/oxidase, N-terminal domain (IPR013786) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 251430 control chromosomes (gnomAD). c.320T>C has been reported in the literature in individuals affected with Medium Chain Acyl-CoA Dehydrogenase Deficiency (examples: Arnold_2010, Smith_2010, Hsu_2008, McKinney_2004). These data indicate that the variant is likely to be associated with disease. The following publications have been ascertained in the context of this evaluation (PMID: 20036593, 20434380, 15171998, 18450854). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014and all classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic.

Comment:
This sequence change replaces leucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 107 of the ACADM protein (p.Leu107Ser). … (more)
This sequence change replaces leucine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 107 of the ACADM protein (p.Leu107Ser). For these reasons, this variant has been classified as Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ACADM protein function. ClinVar contains an entry for this variant (Variation ID: 197615). This variant is also known as p.Leu82Ser. This missense change has been observed in individual(s) with medium-chain acyl-CoA dehydrogenasedeficiency (PMID: 15171998, 18450854, 20036593, 20434380). This variant is present in population databases (rs746136472, gnomAD 0.003%). (less)

Record last updated Sep 29, 2024
This date represents the last time this VCV record was updated. The update may be due to an update to one of the included submitted records (SCVs), or due to an update that ClinVar made to the variant such as adding HGVS expressions or a rs number. So this date may be different from the date of the “most recent submission” reported at the top of this page.
