Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000039947 SCV000063638 benign not specified 2011-10-12 criteria provided, single submitter clinical testing This variant changes an amino acid but is considered to be benign based on its h igh population frequency (>3%).
GeneDx RCV000039947 SCV000169611 benign not specified 2013-04-29 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.

Illumina Clinical Services Laboratory,Illumina RCV000291382 SCV000424383 benign Tibial muscular dystrophy 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease.

Integrated Genetics/Laboratory Corporation of America RCV000039947 SCV001362875 benign not specified 2019-10-30 criteria provided, single submitter clinical testing Variant summary: TTN c.17129C>T (p.Ala5710Val) results in a non-conservative amino acid change located in the I-band of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.057 in 243530 control chromosomes, predominantly at a frequency of 0.18 within the Latino subpopulation in the gnomAD database, including 584 homozygotes. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 288-folds over the estimated maximal expected allele frequency for a pathogenic variant in TTN causing Cardiomyopathy phenotype (0.00063), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. A ClinVar submission (evaluation after 2014) cites the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign.
Genetic Services Laboratory, University of Chicago RCV000039947 SCV000153191 likely benign not specified no assertion criteria provided clinical testing Likely benign based on allele frequency in 1000 Genomes Project or ESP global frequency and its presence in a patient with a rare or unrelated disease phenotype. NOT Sanger confirmed.
