GeneDx RCV000040277 SCV000237209 likely benign not specified 2017-11-09 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 RCV000382285 SCV000423151 uncertain significance 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 Clinical Services Laboratory,Illumina RCV000283374 SCV000423155 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. 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.

Integrated Genetics/Laboratory Corporation of America RCV000040277 SCV001360463 benign not specified 2019-08-13 criteria provided, single submitter clinical testing Variant summary: TTN c.39487C>T (p.Arg13163Cys) results in a non-conservative amino acid change located in the A-band region of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0023 in 248102 control chromosomes in the gnomAD database, including 1 homozygote. The observed variant frequency is approximately 3.7 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.39487C>T has been reported in the literature in sequencing studies of individuals affected with a variety of cardiac phenotypes (example, Pugh_2014). These report(s) do not provide unequivocal conclusions about association of the variant with Cardiomyopathy. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Seven clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Six of these submitters have classified the variant as likely benign (n=5)/benign (n=1). Based on the evidence outlined above, the variant was classified as benign.
