Illumina Laboratory Services, Illumina RCV000333598 SCV000423980 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.
Illumina Laboratory Services, Illumina RCV000381135 SCV000423981 benign 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 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.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV000040055 SCV002571010 likely benign not specified 2022-07-25 criteria provided, single submitter clinical testing Variant summary: TTN c.22940A>G (p.Asn7647Ser) 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 0.00037 in 248780 control chromosomes, predominantly at a frequency of 0.0007 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 2 fold of the estimated maximal expected allele frequency for a pathogenic variant in TTN causing Dilated Cardiomyopathy phenotype (0.00039), strongly suggesting that the variant is a benign polymorphism found primarily in populations of Latino origin. c.22940A>G has been reported in the literature in individuals who have been screened for cardiomyopathy associated genes (examples: Pugh_2014, Michaud_2014, Campuzano_2015, Mademont-Soler_2017, and Martnez-Barrios_2022). These reports do not provide unequivocal conclusions about association of the variant with Dilated Cardiomyopathy. Eight clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as benign (n=1), likely benign (n=5) and VUS (n=2). Based on the evidence outlined above, the variant was classified as likely benign.
