Genes affected
SCN5A (HGNC:10593): (sodium voltage-gated channel alpha subunit 5) The protein encoded by this gene is an integral membrane protein and tetrodotoxin-resistant voltage-gated sodium channel subunit. This protein is found primarily in cardiac muscle and is responsible for the initial upstroke of the action potential in an electrocardiogram. Defects in this gene have been associated with long QT syndrome type 3 (LQT3), atrial fibrillation, cardiomyopathy, and Brugada syndrome 1, all autosomal dominant cardiac diseases. Alternative splicing results in several transcript variants encoding different isoforms. [provided by RefSeq, May 2022]

| Benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Feb 22, 2016 | Variant summary: Variant affects a non-conserved nucleotide and results in a synonymous mutation. 5/5 in silico prediction tools via Alamut predict the variant not to have an effect on normal splicing and while mutation taster predicts the variant to be disease causing. The variant was found predominantly in the Finnish European subcohort of the ExAC project at an allele frequency of 1.5% indicating the variant to be a neutral polymorphism in individuals of Finnish origin. Moreover, a publication (Garca-Molina_ClinGen_2013) and a clinical diagnostic laboratory via ClinVar classifies variant as polymorphism/Benign. Considering all evidence, the variant was classified as Benign. - |

Brugada syndrome 1 Benign:1
| Likely benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 12, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. - |
