Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000152207 SCV000200968 likely benign not specified 2019-05-10 criteria provided, single submitter clinical testing The p.Ile24333Val variant in TTN is classified as likely benign because it has been identified in 3.1% (326/10344) of Ashkenazi Jewish chromosomes (including 1 homozygote) and 0.04% (59/127920) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). Additionally, isoleucine (Ile) at position 24333 is not conserved in evolution and multiple birds and reptiles carry a valine (Val) at this position. Computational prediction tools predict that this variant does not impact the protein. ACMG/AMP Criteria applied: BS1, BP4.
GeneDx RCV000152207 SCV000237602 benign not specified 2017-07-24 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.

Illumina Clinical Services Laboratory,Illumina RCV000369763 SCV000421519 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 RCV000273789 SCV000421520 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.
