Ambry Genetics	RCV000252028	SCV000318055	likely benign	Cardiovascular phenotype	2012-11-28	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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000254386	SCV001362592	benign	not specified	2019-08-26	criteria provided, single submitter	clinical testing	Variant summary: TTN c.98083_98084delinsTT (p.Ala32695Phe) results in a non-conservative amino acid change in the encoded protein sequence. Two of four in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.011 in 280436 control chromosomes in the gnomAD database, including 25 homozygotes. The observed variant frequency is approximately 18 fold of the estimated maximal expected allele frequency for a pathogenic variant in TTN causing Cardiomyopathy phenotype (0.00063), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.98083_98084delinsTT in individuals affected with Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, and all of them classified the variant as benign. Based on the evidence outlined above, the variant was classified as benign.
