not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jul 06, 2015 | The p.Arg30577Gln variant in TTN has been previously identified by our laborator y in 1 child with severe RVH and 1 child with DCM who also carried a likely path ogenic variant in this gene. It has been identified in 2/9788 African chromosome s by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbS NP rs371531675). Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Arg30577Gln variant is uncertain. - |
