Illumina Laboratory Services, Illumina RCV000284293 SCV000424569 likely benign 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 and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease.

Illumina Laboratory Services, Illumina RCV000394055 SCV000424571 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2J 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 RCV000039891 SCV001363705 benign not specified 2019-08-27 criteria provided, single submitter clinical testing Variant summary: TTN c.13316A>G (p.Tyr4439Cys) results in a non-conservative amino acid change located in the I-band of the encoded protein sequence. Two of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0056 in 248668 control chromosomes, predominantly at a frequency of 0.0082 within the Non-Finnish European subpopulation in the gnomAD database, including 3 homozygotes. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 13-folds over the estimated maximal expected allele frequency for a pathogenic variant in TTN causing Cardiomyopathy phenotype (0.00063), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. Eight ClinVar submissions (evaluation after 2014) cite the variant seven times as likely benign/benign and once as uncertain significance. Based on the evidence outlined above, the variant was classified as benign.
