RCV001837774 | SCV000284765 | likely benign | Hypercholesterolemia, autosomal dominant, type B; Familial hypobetalipoproteinemia 1 | 2023-12-08 | criteria provided, single submitter | clinical testing | |
Ambry Genetics | RCV002450670 | SCV002739873 | uncertain significance | Cardiovascular phenotype | 2024-01-23 | criteria provided, single submitter | clinical testing | The c.2657A>G (p.N886S) alteration is located in exon 18 (coding exon 18) of the APOB gene. This alteration results from a A to G substitution at nucleotide position 2657, causing the asparagine (N) at amino acid position 886 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

New York Genome Center | RCV001837774 | SCV003925180 | uncertain significance | Hypercholesterolemia, autosomal dominant, type B; Familial hypobetalipoproteinemia 1 | 2022-06-15 | criteria provided, single submitter | clinical testing | The c.2657A>G p.(Asn886Ser) variant identified in the APOB gene is predicted to result in the substitution of an Asparagine for Serineat amino acid 886/4564 (exon 18/29). This variant is found with low frequency in population databases gnomAD, BRAVO-TOPMed Freeze 8, All of Us (allele frequency=1.1e-4) suggesting it is not a common benign variant in the populations represented in those databases. In silico algorithms do not predict a damaging effect to the function of the canonical protein (REVEL=0.153). This variant reported in ClinVar as a Variant of Uncertain Significance [VarID:237742] and to our current knowledge has not been reported in affected individuals in the literature. Given the lack of compelling evidence for its pathogenicity, the c.2657A>Gp.(Asn886Ser) variant identified in the APOB gene is reported as a Variant of Uncertain Significance. |
