Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000040661	SCV000064352	likely benign	not specified	2012-03-19	criteria provided, single submitter	clinical testing	Asn24319Asn in exon 275 of TTN: This variant is not expected to have clinical si gnificance because it does not alter an amino acid residue and is not located wi thin the splice consensus sequence. It has been identified in 0.3% (8/3004) of A frican American chromosomes from a broad population by the NHLBI Exome Sequencin g Project (http://evs.gs.washington.edu/EVS). Asn24319Asn in exon 275 of TTN (a llele frequency = 0.3%, 8/3004) **
GeneDx	RCV000040661	SCV000169378	benign	not specified	2014-04-03	criteria provided, single submitter	clinical testing	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.

Ambry Genetics	RCV000620038	SCV000737339	likely benign	Cardiovascular phenotype	2017-12-12	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.
