Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000040715	SCV000064406	uncertain significance	not specified	2013-02-11	criteria provided, single submitter	clinical testing	The Ser25901Cys variant in TTN has not been reported in the literature nor previ ously identified by our laboratory. This variant has been seen in 1/8300 Europea n American chromosomes in a broad population by the NHLBI Exome Sequencing Proje ct (http://evs.gs.washington.edu/EVS; dbSNP rs202040332). Computational analyses (biochemical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIF T) do not provide strong support for or against an impact to the protein. In sum mary, additional information is needed to fully assess the variant's clinical si gnificance.
GeneDx	RCV000040715	SCV000236795	benign	not specified	2016-12-07	criteria provided, single submitter	clinical testing	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Illumina Laboratory Services, Illumina	RCV001134723	SCV001294478	benign	Tibial muscular dystrophy	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	RCV001134724	SCV001294479	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.

Illumina Laboratory Services, Illumina	RCV001134725	SCV001294480	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.

Ambry Genetics	RCV002354205	SCV002649783	benign	Cardiovascular phenotype	2018-09-24	criteria provided, single submitter	clinical testing	This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, 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.
