RCV001838080 | SCV001392677 | uncertain significance | Hypercholesterolemia, autosomal dominant, type B; Familial hypobetalipoproteinemia 1 | 2019-07-24 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with APOB-related conditions. ClinVar contains an entry for this variant (Variation ID: 548035). This sequence change replaces alanine with serine at codon 3837 of the APOB protein (p.Ala3837Ser). The alanine residue is weakly conserved and there is a moderate physicochemical difference between alanine and serine. |
Ambry Genetics | RCV003303091 | SCV004000640 | uncertain significance | Cardiovascular phenotype | 2023-05-21 | criteria provided, single submitter | clinical testing | The p.A3837S variant (also known as c.11509G>T), located in coding exon 26 of the APOB gene, results from a G to T substitution at nucleotide position 11509. The alanine at codon 3837 is replaced by serine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
