Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PM5PP3_Strong
The NM_000019.4(ACAT1):c.622C>G(p.Arg208Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R208Q) has been classified as Likely pathogenic.

Deficiency of acetyl-CoA acetyltransferase Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 05, 2019 | This sequence change replaces arginine with glycine at codon 208 of the ACAT1 protein (p.Arg208Gly). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and glycine. This variant is not present in population databases (ExAC no frequency). This variant has been observed to be homozygous in an individual with clinical features of beta-ketothiolase deficiency (Invitae). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). The observation of one or more missense substitutions at this codon (p.Arg208Gln and p.Arg208Gly) in affected individuals suggests that this may be a clinically significant residue (PMID: 17236799, Invitae). 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. - |
