Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000040751	SCV000064442	likely benign	not specified	2013-03-06	criteria provided, single submitter	clinical testing	Asp26936Asn in exon 280 of TTN: This variant is not expected to have clinical si gnificance due to a lack of conservation across species. Multiple mammals, inclu ding mouse, bushbaby, and horse, have an asparagine (Asp) at this position despi te high nearby amino acid conservation. In addition, computational analyses (Ali gnGVGD, PolyPhen2, SIFT) do not suggest a high likelihood of impact to the prote in. This variant has been identified in 1/8260 European American chromosomes fro m a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washin gton.edu/EVS).

Ambry Genetics	RCV000618971	SCV000736514	likely benign	Cardiovascular phenotype	2016-02-25	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
