Invitae RCV002535567 SCV003517335 uncertain significance Hypercholesterolemia, autosomal dominant, type B; Familial hypobetalipoproteinemia 1 2022-04-20 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 240 of the APOB protein (p.Ser240Asn). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with APOB-related conditions. ClinVar contains an entry for this variant (Variation ID: 630660). 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: "Benign"; Align-GVGD: "Class C0"). 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.
