ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000733860 SCV004563364 uncertain significance not provided 2023-09-28 criteria provided, single submitter clinical testing The TTN c.30196G>C; p.Glu10066Gln variant (rs370072382; ClinVar Variation ID: 404868) is rare in the general population (<0.2% 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. Yet, evidence suggests that the vast majority of such missense variants do not contribute to the clinical outcome of DCM (Begay 2015). Thus, the clinical significance of the p.Glu10066Gln variant cannot be determined with certainty. References: Begay RL et al. Role of Titin Missense Variants in Dilated Cardiomyopathy.
