Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000039883	SCV000063574	likely benign	not specified	2011-12-19	criteria provided, single submitter	clinical testing	Asn4127Asn in 52 of TTN: This variant is not expected to have clinical significa nce because it does not alter an amino acid residue, is not located within the s plice consensus sequence. It has been reported in 1/6693 European American chro mosomes and 1/3179 African American chromosomes by the NHBLI Exome sequencing pr oject (rs143845692; note: this cohort contained individuals with heart disease, http://evs.gs.washington.edu/EVS/). Asn4127Asn in 52 of TTN (rs143845692; NHBLI Exome Seq Project; allele frequency = 0.01-0.03%)
Ambry Genetics	RCV000245367	SCV000317959	likely benign	Cardiovascular phenotype	2013-01-10	criteria provided, single submitter	clinical testing	This alteration is classified as likely 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	RCV000367309	SCV000424622	benign	Myopathy, myofibrillar, 9, with early respiratory failure	2018-01-12	criteria provided, single submitter	clinical testing	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 benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.
Illumina Laboratory Services, Illumina	RCV000277429	SCV000424623	uncertain significance	Dilated cardiomyopathy 1G	2018-01-12	criteria provided, single submitter	clinical testing	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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
