Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000152534 SCV000201728 benign not specified 2012-03-19 criteria provided, single submitter clinical testing p.Thr334Thr in Exon 07 of TTN: This variant is not expected to have clinical sig nificance because it does not alter an amino acid residue, is not located within the splice consensus sequence and has been identified in 0.5% (18/3738) of Afri can American chromosomes from a broad population by the NHLBI Exome Sequencing P roject (http://evs.gs.washington.edu/EVS; dbSNP rs148094198).
Labcorp Genetics (formerly Invitae), Labcorp RCV001083824 SCV000261791 benign Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2024-01-29 criteria provided, single submitter clinical testing
Illumina Laboratory Services, Illumina RCV000389385 SCV000425312 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2J 2018-01-12 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 Laboratory Services, Illumina RCV000332417 SCV000425314 benign Tibial muscular dystrophy 2018-01-12 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 Laboratory Services, Illumina RCV000382294 SCV000425315 benign Myopathy, myofibrillar, 9, with early respiratory failure 2018-01-12 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.

GeneDx RCV000152534 SCV000515074 benign not specified 2015-08-24 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.
