Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000039987 SCV000063678 uncertain significance not specified 2015-03-04 criteria provided, single submitter clinical testing Variant classified as Uncertain Significance - Favor Benign. The p.Asp6524Asn va riant in TTN has been previously identified by our laboratory in 4 individuals w ith cardiomyopathy (1 infant with LVNC, 1 infant with RCM, 1 adult with HCM, and 1 adult with DCM). This variant has also been identified in 0.1% (85/66642) of European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broa dinstitute.org; dbSNP rs72648973). Computational prediction tools and conservati on analysis suggest that this variant may impact the protein, though this inform ation is not predictive enough to determine pathogenicity. In summary, while the clinical significance of the p.Asp6524Asn variant is uncertain, the broad pheno typic spectrum seen in individuals with this variant and its frequency in the ge neral population suggest that it is more likely to be benign.
GeneDx RCV000039987 SCV000238331 likely benign not specified 2018-01-11 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 RCV000299836 SCV000424220 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 RCV000359255 SCV000424221 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.
