Ambry Genetics | RCV004035423 | SCV001444677 | likely benign | Cardiovascular phenotype | 2022-12-21 | 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. |

RCV001841200 | SCV001734410 | uncertain significance | Cardiac arrhythmia | 2023-03-20 | criteria provided, single submitter | clinical testing | This missense variant replaces alanine with serine at codon 399 of the KCNQ1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with KCNQ1-related disorders in the literature. This variant has been identified in 22/251228 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |

RCV001294856 | SCV004836398 | uncertain significance | Long QT syndrome | 2023-12-01 | criteria provided, single submitter | clinical testing | This missense variant replaces alanine with serine at codon 399 of the KCNQ1 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 22/251228 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The relatively high frequency of this variant in the general population suggests that this variant is unlikely to be disease-causing. However, additional studies are necessary to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
