RCV003802640 | SCV004591533 | uncertain significance | Hypercholesterolemia, autosomal dominant, type B; Familial hypobetalipoproteinemia 1 | 2022-12-25 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 1858 of the APOB protein (p.Lys1858Glu). This variant is not present in population databases (gnomAD no frequency). 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 APOB protein function. This variant has not been reported in the literature in individuals affected with APOB-related conditions. |
