Invitae | RCV000560501 | SCV000636468 | uncertain significance | Progressive myoclonic epilepsy | 2023-08-17 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 304 of the SCARB2 protein (p.Asn304Ser). This variant is present in population databases (rs150870503, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with SCARB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 462928). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SCARB2 protein function. 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. |
Ambry Genetics | RCV002377055 | SCV002686015 | uncertain significance | Inborn genetic diseases | 2020-01-29 | criteria provided, single submitter | clinical testing | The p.N304S variant (also known as c.911A>G), located in coding exon 7 of the SCARB2 gene, results from an A to G substitution at nucleotide position 911. The asparagine at codon 304 is replaced by serine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. 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. |
