Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000040295	SCV000063986	uncertain significance	not specified	2016-11-15	criteria provided, single submitter	clinical testing	Variant classified as Uncertain Significance - Favor Benign. The p.Ile13750Thr v ariant in TTN has been identified by our laboratory in several individuals with various types of cardiomyopathy, did not segregate with disease in 1 relative wi th HCM, and has been identified in 0.2% (119/66356) of European chromosomes, inc luding 1 homozygote, by the Exome Aggregation Consortium (ExAC, http://exac.broa dinstitute.org; dbSNP rs72677243). Computational prediction tools and conservati on analysis suggest that the p.Ile13750Thr variant may impact the protein, thoug h this information is not predictive enough to determine pathogenicity. In summa ry, while the clinical significance of the p.Ile13750Thr variant is uncertain, i ts frequency suggests that it is more likely to be benign.

Illumina Laboratory Services, Illumina	RCV001130555	SCV001290135	uncertain significance	Early-onset myopathy with fatal cardiomyopathy	2017-05-08	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 Laboratory Services, Illumina	RCV000655929	SCV001290136	benign	Tibial muscular dystrophy	2017-05-08	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.

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 Laboratory Services, Illumina	RCV001131282	SCV001290898	benign	Dilated cardiomyopathy 1G	2017-05-08	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 rule this variant out of causing disease. Therefore, this variant is classified as benign.

Foundation for Research in Genetics and Endocrinology, FRIGE's Institute of Human Genetics	RCV000655929	SCV000747737	uncertain significance	Tibial muscular dystrophy	2014-07-07	no assertion criteria provided	clinical testing	The observed variant c.22334T>C (p.I7445T) is reported in 1000 Genomes and ExAC databases with a minor allele frequency of 0.0004 and 0.0012 respectively. The in silico prediction of the above variant is disease causing by MutationTaster2, tolerated by SIFT and probably damaging by PolyPhen2.
