RCV003089512 | SCV003475370 | uncertain significance | Holocarboxylase synthetase deficiency | 2022-07-12 | criteria provided, single submitter | clinical testing | 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. 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 not expected to disrupt HLCS protein function. This variant has not been reported in the literature in individuals affected with HLCS-related conditions. This variant is present in population databases (rs772486641, gnomAD 0.006%). This sequence change replaces glutamine, which is neutral and polar, with histidine, which is basic and polar, at codon 673 of the HLCS protein (p.Gln673His). |
