Color Diagnostics, LLC DBA Color Health RCV001842611 SCV001360240 uncertain significance Cardiac arrhythmia 2018-12-10 criteria provided, single submitter clinical testing Variant of Uncertain Significance due to insufficient evidence: This missense variant is located in the transmembrane domain DIII of the SCN5A protein. Computational prediction tools and conservation analyses suggest that this variant may have deleterious impact on the protein function. Computational splicing tools suggest that this variant may not impact RNA splicing. An experimental study has shown that this variant causes abnormal electrophysiological phenotype in cells (PMID: 25904541). This variant has been reported in an individual affected with long QT syndrome (PMID: 25904541). This variant has also been identified in 3/242868 chromosomes in the general population by the Genome Aggregation Database (gnomAD). Available evidence is insufficient to determine the pathogenicity of this variant conclusively.
GeneDx RCV001092239 SCV001987707 uncertain significance not provided 2019-07-03 criteria provided, single submitter clinical testing Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Identified in an individual with long QT syndrome type 3, but familial segregation information and additional clinical information were not included (Wild et al., 2016); This variant is associated with the following publications: (PMID: 25904541, 29728395, 27566755, 30662450)
