Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jul 22, 2015 | The p.Arg24338Gln variant in TTN has not been previously reported in individuals with cardiomyopathy, but has been identified in 1/16496 South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSN P rs536183519). Computational prediction tools and conservation analysis suggest that the variant may impact the protein, though this information is not predict ive enough to determine pathogenicity. In summary, the clinical significance of the p.Arg24338Gln variant is uncertain. - |
