Invitae RCV001838231 SCV000954124 uncertain significance Hypercholesterolemia, autosomal dominant, type B; Familial hypobetalipoproteinemia 1 2018-07-21 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. 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"). This variant has not been reported in the literature in individuals with APOB-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces lysine with methionine at codon 2148 of the APOB protein (p.Lys2148Met). The lysine residue is weakly conserved and there is a moderate physicochemical difference between lysine and methionine.
GeneDx RCV001759577 SCV001986947 uncertain significance not provided 2019-05-07 criteria provided, single submitter clinical testing Has not been previously published as pathogenic or benign to our knowledge; Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function
