ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000082442 SCV000884797 uncertain significance not provided 2018-05-15 criteria provided, single submitter clinical testing The TTN c.81682G>A; p.Val27228Met variant is rare in the general population (<1% allele frequency in the Genome Aggregation Database) and has not been reported in the medical literature in association with dilated cardiomyopathy (DCM) or other TTN-related disease. 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 p.Val27228Met variant cannot be determined with certainty.

GeneDx RCV000154897 SCV000237715 likely benign not specified 2017-09-22 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.
