Invitae RCV000643143 SCV000764830 uncertain significance Dilated cardiomyopathy 1G; Autosomal recessive limb-girdle muscular dystrophy type 2J 2017-11-25 criteria provided, single submitter clinical testing
ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV000756840 SCV000884778 uncertain significance not provided 2017-07-07 criteria provided, single submitter clinical testing The p.Glu9142Lys variant (rs772195716) has not been reported in the medical literature, is not listed in gene-specific variant databases, nor has it been previously identified in our laboratory. It is listed in the Genome Aggregation Database (gnomAD) browser with an overall frequency of 0.007% (identified in 9 out of 129,008 chromosomes). The glutamic acid at codon 9142 is moderately conserved considering 10 species up to frog (Alamut software v2.9), and computational analyses return mixed results regarding the effect of this variant on TTN protein structure/function (SIFT: damaging, PolyPhen2: benign, and Mutation Taster: polymorphism). However, based on the available information, the clinical significance of the p.Glu9142Lys variant cannot be determined with certainty.
GeneDx RCV000756840 SCV000981857 likely benign not provided 2018-04-05 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 Laboratory Services, Illumina RCV001129321 SCV001288837 uncertain significance 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, 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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002222576 SCV002500181 uncertain significance not specified 2022-03-07 criteria provided, single submitter clinical testing Variant summary: TTN c.27424G>A (p.Glu9142Lys) results in a conservative amino acid change located in the I-band of the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 6.8e-05 in 103098 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.27424G>A in individuals affected with Dilated Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (Likely benign n=1, VUS n=3). Based on the evidence outlined above, the variant was classified as uncertain significance.
