Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000150863	SCV000198422	benign	not specified	2012-05-07	criteria provided, single submitter	clinical testing	"Ile145Ile in Exon 02 of KCNQ1: This variant is not expected to have clinical si gnificance because it does not alter an amino acid residue, is not located withi n the splice consensus sequence, and has been identified in 4.2% (5/120) of chro mosomes from a population in the dbSNP database (http://www.ncbi.nlm.nih.gov/pro jects/SNP; rs1800170)."

Ambry Genetics	RCV000244395	SCV000317515	benign	Cardiovascular phenotype	2015-04-21	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: 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.
Illumina Laboratory Services, Illumina	RCV000357067	SCV000370220	likely benign	Jervell and Lange-Nielsen syndrome 1	2017-04-27	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.
Illumina Laboratory Services, Illumina	RCV000262280	SCV000370221	likely benign	Atrial fibrillation, familial, 3	2017-04-27	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.
Illumina Laboratory Services, Illumina	RCV001093970	SCV000370222	likely benign	Long QT syndrome 1	2017-04-27	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 Laboratory Services, Illumina	RCV000276186	SCV000370224	likely benign	Short QT syndrome type 2	2017-04-27	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.
