RCV001882814 | SCV002275679 | uncertain significance | Very long chain acyl-CoA dehydrogenase deficiency | 2022-07-22 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 644 of the ACADVL protein (p.Arg644Gln). This variant is present in population databases (rs774762384, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with ACADVL-related conditions. ClinVar contains an entry for this variant (Variation ID: 1302622). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine 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. |

RCV002266009 | SCV002547967 | uncertain significance | not specified | 2022-05-03 | criteria provided, single submitter | clinical testing | Variant summary: ACADVL c.1931G>A (p.Arg644Gln) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 2e-05 in 251432 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1931G>A in individuals affected with Very Long Chain Acyl-CoA Dehydrogenase Deficiency and no experimental evidence demonstrating its impact on protein function have been reported. Two ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. |
