Description

The Arg30180His variant in TTN has been identified by our laboratory in 2 indivi duals with DCM (LMM unpublished data) and was not identified in large population studies. Computational analyses (biochemical amino acid properties, conservatio n, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support for or against an impact to the protein. Additional information is needed to fully assess the c linical significance of this variant.
