Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000154998	SCV000204680	likely benign	not specified	2015-05-21	criteria provided, single submitter	clinical testing	p.Val4012Met in exon 45B in TTN: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, 5 mammals (bushbaby, squirrel, hedgehog, aardvark, and Tasmanian devil) ha ve a methionine (Met) at this position despite amino acid conservation at nearby positions. It has been identified in 0.1% (93/66496) of European chromosomes, i ncluding 1 homozygote, by the Exome Aggregation Consortium (ExAC, http://exac.br oadinstitute.org; dbSNP rs201437752).

Ambry Genetics	RCV000621842	SCV000735760	likely benign	Cardiovascular phenotype	2018-08-23	criteria provided, single submitter	clinical testing	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, 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.
