Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000040350 SCV000064041 uncertain significance not specified 2015-07-06 criteria provided, single submitter clinical testing The p.Ser15463Gly variant in TTN has been previously identified by our laborator y in 1 child with DCM who also carried a likely pathogenic variant in this gene. It has also been identified in 1/712 chromosomes of unspecified ancestry by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs397 517615). Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinica l significance of the p.Ser15463Gly variant is uncertain.

Clinical Genomics Laboratory, Washington University in St. Louis RCV005051742 SCV005685432 uncertain significance Hypertrophic cardiomyopathy 9 2024-10-17 criteria provided, single submitter clinical testing The TTN c.54091A>G (p.Ser18031Gly) variant, to our knowledge, has not been reported in the medical literature. The highest population minor allele frequency in the population database genome aggregation database (v.2.1.1) is 0.02% in the other populations. This variant was reported in the ClinVar database as a variant of uncertain significance by four submitters (ClinVar ID: 47080). Computational predictors indicate this variant has no impact on TTN function. Due to limited information and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time.
