GeneDx RCV000039885 SCV000238229 likely benign not specified 2017-02-21 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.

Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000039885 SCV000063576 uncertain significance not specified 2016-01-29 criteria provided, single submitter clinical testing Variant classified as Uncertain Significance - Favor Benign. 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,; 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.
