Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000154645 SCV000204320 uncertain significance not specified 2014-09-19 criteria provided, single submitter clinical testing Variant classified as Uncertain Significance - Favor Benign. The Ile7588Val vari ant in TTN has been identified by our laboratory in 1 Caucasian adult with HCM w ho also carried a pathogenic variant in another gene and 1 adult of unspecified ethnicity with DCM. This variant has been also been identified in 0.1% (8/8156) of European American chromosomes by the NHLBI Exome Sequencing Project (http://e vs.gs.washington.edu/EVS/, Ng 2013; dbSNP rs72648989). Computational prediction tools and conservation analysis suggest that the Ile7588Val variant may not impa ct the protein, though this information is not predictive enough to rule out pat hogenicity. In addition, 1 fish (yellowbelly pufferfish) carries a valine at thi s position, raising the possibility that this change may be tolerated. In summar y, while the clinical significance of the Ile7588Val variant is uncertain, its f requency in controls suggests that it is more likely to be benign.
GeneDx RCV000154645 SCV000238376 likely benign not specified 2017-11-27 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 RCV001131542 SCV001291169 uncertain significance Myopathy, early-onset, with fatal cardiomyopathy 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.

Illumina Clinical Services Laboratory,Illumina RCV001131544 SCV001291171 benign Myopathy, myofibrillar, 9, with early respiratory failure 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.
