GeneDx RCV000080769 SCV000168142 benign not specified 2013-11-14 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 RCV000382472 SCV000482229 benign Dilated cardiomyopathy 3B 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.

However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.17 in 204704 control chromosomes, predominantly within the East Asian subpopulation at a frequency of 0.35 in the gnomAD database, including 584 homozygotes and 1751 hemizygotes. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 30 fold of the estimated maximal expected allele frequency for a pathogenic variant in DMD causing Dystrophinopathies phenotype (0.011), strongly suggesting that the variant is a benign polymorphism. To our knowledge, no occurrence of c.7728T>C in individuals affected with Dystrophinopathies and no experimental evidence demonstrating its impact on protein function have been reported. Six ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cite the variant as likely benign/benign. Based on the evidence outlined above, the variant was classified as benign.
