Description

The Arg19629Gln variant in TTN has not been reported in the literature nor previ ously identified by our laboratory. This variant has been identified in 1/3960 A frican American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs .washington.edu/EVS/). Computational analyses (biochemical amino acid properties , conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong support fo r or against an impact to the protein. Additional information is needed to fully assess the clinical significance of this variant.

Description

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
