Description

This sequence change replaces glutamine with histidine at codon 627 of the ACADVL protein (p.Gln627His). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and histidine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with ACADVL-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
