Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000152233 SCV000201029 uncertain significance not specified 2016-05-06 criteria provided, single submitter clinical testing Variant classified as Uncertain Significance - Favor Benign. The p.Ile20720Met v ariant in TTN has been identified by our laboratory in 1 Hispanic individual wit h LVNC and Ebstein's anomaly and 1 individual with neonatal onset cardiomyopathy . However, the individual with neonatal onset cardiomyopathy carried 2 pathogeni c variants in another gene that were sufficient to explain their disease. This v ariant has also been identified in 0.1% (10/9520) of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs3688 67993). Computational prediction tools and conservation analysis suggest that th e variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, while the clinical significance of the p.Ile20720Met variant is uncertain, these data suggest that it is more like ly to be benign.

GeneDx RCV000152233 SCV000730899 likely benign not specified 2018-03-13 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 RCV001130195 SCV001289765 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.
Illumina Clinical Services Laboratory,Illumina RCV001130196 SCV001289766 uncertain significance Dilated cardiomyopathy 1G 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, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.
