GeneDx RCV000040547 SCV000237475 likely benign not specified 2017-10-30 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 RCV000040547 SCV000064238 uncertain significance not specified 2014-09-25 criteria provided, single submitter clinical testing Variant classified as Uncertain Significance - Favor Benign. The Gly20706Asp var iant in TTN has been identified by our laboratory in 1 Caucasian adult with DCM and LBBB and 1 Caucasian adult with ARVC (Pugh 2014; LMM unpublished data). In a ddition, this variant has been identified in 0.2% (19/8258) of European American chromosomes by the NHLBI Exome Sequencing Project ( /EVS/; dbSNP rs201043950). Computational prediction tools and conservation analy sis do not provide strong support for or against an impact to the protein. In su mmary, while the clinical significance of the Gly20706Asp variant is uncertain, its frequency suggests that it is more likely to be benign.
