Description

The p.Ala31496Thr variant in TTN has been identified by our laboratory in two in dividuals: an infant with DCM and adolescent with HCM. In addition, this variant has been identified in 22/66708 European chromosomes by the Exome Aggregation C onsortium (ExAC, http://exac.broadinstitute.org; dbSNP rs200237973). Computation al prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of th e p.Ala31496Thr variant is uncertain.
