RCV001869109 | SCV002239954 | uncertain significance | Hypercholesterolemia, autosomal dominant, type B; Familial hypobetalipoproteinemia 1 | 2021-05-31 | 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 conditions. ClinVar contains an entry for this variant (Variation ID: 630627). This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with histidine at codon 3080 of the APOB protein (p.Pro3080His). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and histidine. |
| Ambry Genetics | RCV004027295 | SCV005034747 | uncertain significance | Cardiovascular phenotype | 2023-12-15 | criteria provided, single submitter | clinical testing | The p.P3080H variant (also known as c.9239C>A), located in coding exon 26 of the APOB gene, results from a C to A substitution at nucleotide position 9239. The proline at codon 3080 is replaced by histidine, 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. |
