Ambry Genetics RCV000254435 SCV000318127 likely benign Cardiovascular phenotype 2013-09-24 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Illumina Laboratory Services, Illumina RCV000352447 SCV000423133 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.
Illumina Laboratory Services, Illumina RCV000392384 SCV000423134 uncertain significance Dilated cardiomyopathy 1G 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 RCV000040280 SCV001361637 benign not specified 2019-08-19 criteria provided, single submitter clinical testing Variant summary: TTN c.39611G>A (p.Arg13204Gln) results in a conservative amino acid change located in the A-band region of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0034 in 247508 control chromosomes in the gnomAD database, including 3 homozygotes. The observed variant frequency is approximately 5.4 fold of the estimated maximal expected allele frequency for a pathogenic variant in TTN causing Cardiomyopathy phenotype (0.00063), strongly suggesting that the variant is benign. c.39611G>A has been reported in the literature in individuals affected with Cardiomyopathy (example Pugh_2014). These report(s) do not provide unequivocal conclusions about association of the variant with Cardiomyopathy. At-least one co-occurrence with another likely pathogenic variant has been reported in an individual with a clinical diagnosis and family history of DCM ( TTN c.50143+1G>A, Pugh_2014), providing supporting evidence for a benign role. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation (benign=2, likely benign = 2, VUS = 1). Based on the evidence outlined above, the variant was classified as benign.
