The p.Lys4194Arg va riant in TTN has been previously identified by our laboratory in 2 adults with D CM, 1 adult with HCM, and 1 infant with HCM and LV enlargement. This variant has been identified in 0.1% (85/66092) of European chromosomes by the Exome Aggrega tion Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs190636272). Compu tational prediction tools and conservation analysis do not provide strong suppor t for or against an impact to the protein. In summary, while the clinical signif icance of the p.Lys4194Arg variant is uncertain, its frequency suggests that it is more likely to be benign.

Illumina Laboratory Services, Illumina	RCV001130570	SCV001290151	benign	Tibial muscular dystrophy	2017-10-02	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.
Illumina Laboratory Services, Illumina	RCV001130571	SCV001290152	uncertain significance	Dilated cardiomyopathy 1G	2017-10-02	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. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance.
