Description

The p.Asp2140Glu variant in TTN has not been previously reported in individuals with cardiomyopathy, but has been identified in 4/66660 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Computa tional prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance o f the p.Asp2140Glu variant is uncertain.
