Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000454727 SCV000540294 uncertain significance not specified 2016-12-16 criteria provided, single submitter clinical testing Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant has been reported in an individual with Brugada syndrome who was compound het for this and an Arg1629X variant in SCN5A. Electrophysiological experiments showed that the variant had little effect on current density alone (Tan 2015). It was identified in 3 additional patients with Brugada syndrome. This variant is present in ClinVar with no classification. It has a Max MAF of 0.18% in ExAC (9 alleles) and 0.13% in gnomAD (25 alleles). This variant is predicted to be pathogenic by prediction tools.

Mendelics RCV000987236 SCV001136486 uncertain significance Brugada syndrome 1 2019-05-28 criteria provided, single submitter clinical testing
Illumina Clinical Services Laboratory,Illumina RCV001144461 SCV001305060 uncertain significance Sick sinus syndrome 1, autosomal recessive 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Clinical Services Laboratory,Illumina RCV000987236 SCV001305061 likely benign Brugada syndrome 1 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
Illumina Clinical Services Laboratory,Illumina RCV001144462 SCV001305062 benign Long QT syndrome 3 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign.
Illumina Clinical Services Laboratory,Illumina RCV001144463 SCV001305063 uncertain significance Progressive familial heart block, type 1A 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Clinical Services Laboratory,Illumina RCV001146370 SCV001307113 uncertain significance Paroxysmal familial ventricular fibrillation 1 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
Illumina Clinical Services Laboratory,Illumina RCV001146371 SCV001307114 likely benign Dilated cardiomyopathy 1E 2017-04-28 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
