Illumina Clinical Services Laboratory,Illumina	RCV000148598	SCV000348781	benign	Emery-Dreifuss muscular dystrophy	2018-03-06	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	RCV000041345	SCV000917597	benign	not specified	2018-07-30	criteria provided, single submitter	clinical testing	Variant summary: LMNA c.357C>T (p.Arg119Arg) alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0033 in 277140 control chromosomes in the gnomAD database, including 2 homozygotes. The observed variant frequency is approximately 13-fold of the estimated maximal expected allele frequency for a pathogenic variant in LMNA causing Cardiomyopathy phenotype (0.00025), strongly suggesting that the variant is benign. The variant, c.357C>T, has been reported in the literature and classified as likely benign by the authors (Dorschner_2013). 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 (6x likely benign/benign, 1x VUS). Based on the evidence outlined above, the variant was classified as benign.

Illumina Clinical Services Laboratory,Illumina	RCV001101878	SCV001258520	uncertain significance	Dilated cardiomyopathy 1A	2018-03-06	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.
