Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000040860	SCV000064551	uncertain significance	not specified	2011-12-21	criteria provided, single submitter	clinical testing	The Ala30052Val variant (TTN) has not been previously reported nor previously id entified by our laboratory. Alanine (Ala) at position 30052 is highly conserved across evolutionarily distant species, increasing the likelihood that a change w ould not be tolerated. Computational predictions on the impact to the protein ar e mixed (AlignGVGD = benign, SIFT = pathogenic), though the accuracy of these to ols is unknown. Additional information is needed to fully assess the clinical si gnificance of the Ala30052Val variant.
Illumina Laboratory Services, Illumina	RCV000303221	SCV000420493	uncertain significance	Early-onset myopathy with fatal cardiomyopathy	2018-01-13	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.
Illumina Laboratory Services, Illumina	RCV000393698	SCV000420495	benign	Tibial muscular dystrophy	2018-01-13	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.

Ambry Genetics	RCV000619770	SCV000735736	likely benign	Cardiovascular phenotype	2019-02-25	criteria provided, single submitter	clinical testing	This alteration is classified as likely 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.
