The p.Arg15050Cys v ariant in TTN has been previously identified by our laboratory in 1 adult with D CM, who carried a likely pathogenic variant in another gene, and in 1 adult with HCM. This variant has been identified in 0.2% (146/66698) of European chromosom es by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; db SNP rs201213901). Computational prediction tools and conservation analysis sugge st that this variant may impact the protein, though this information is not pred ictive enough to determine pathogenicity. In summary, while the clinical signifi cance of the p.Arg15050Cys variant is uncertain, its frequency in the general po pulation suggests that it is more likely to be benign.

The clinical relevance of rare missense variants in this gene, which are identified on average once per individual sequenced in affected populations (Herman 2012), is not well understood. While the clinical significance of such variants is considered uncertain, evidence suggests that the vast majority of missense variants do not contribute to the clinical outcome of DCM (Begay 2015). Given the available evidence, the clinical significance of the c.45148C>T; p.Arg15050Cys variant cannot be determined with certainty.

Illumina Laboratory Services, Illumina	RCV001129508	SCV001289041	uncertain significance	Dilated cardiomyopathy 1G	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 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.

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.

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.

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.
