Genes affected

ACAD9 (HGNC:21497): (acyl-CoA dehydrogenase family member 9) This gene encodes a member of the acyl-CoA dehydrogenase family. Members of this family of proteins localize to the mitochondria and catalyze the rate-limiting step in the beta-oxidation of fatty acyl-CoA. The encoded protein is specifically active toward palmitoyl-CoA and long-chain unsaturated substrates. Mutations in this gene cause acyl-CoA dehydrogenase family member type 9 deficiency. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Mar 2010]

This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 523 of the ACAD9 protein (p.Ile523Thr). This variant is present in population databases (rs747463129, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with ACAD9-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C65". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
