| Invitae | RCV001378187 | SCV001575698 | likely pathogenic | Deficiency of acetyl-CoA acetyltransferase | 2020-08-04 | criteria provided, single submitter | clinical testing | 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 expected to disrupt ACAT1 protein function. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.His397 amino acid residue in ACAT1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 15128923, 20157782). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. This variant has not been reported in the literature in individuals with ACAT1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with arginine at codon 397 of the ACAT1 protein (p.His397Arg). The histidine residue is highly conserved and there is a small physicochemical difference between histidine and arginine. |
