Ambry Genetics | RCV002335782 | SCV002644057 | likely benign | Cardiovascular phenotype | 2024-11-26 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |

RCV003096593 | SCV003002921 | uncertain significance | Long QT syndrome 10 | 2022-05-07 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 169 of the SCN4B protein (p.Val169Ile). 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. This variant has not been reported in the literature in individuals affected with SCN4B-related conditions. This variant is present in population databases (rs149457565, gnomAD 0.05%), and has an allele count higher than expected for a pathogenic variant. |
