Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000038034 SCV000061700 benign not specified 2018-04-04 criteria provided, single submitter clinical testing Tyr1355Tyr in exon 23 of DSP: This variant is classified as benign because it d oes not alter an amino acid residue and is not located within the splice consens us sequence. Computational tools do not predict an impact on splicing. It has b een identified in 0.1% (158/126102) of European chromosomes by the Genome Aggreg ation Databsae (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs148478829). AC MG/AMP Criteria applied: BA1; BP4; BP7.

Illumina Clinical Services Laboratory,Illumina RCV000269608 SCV000465018 uncertain significance Skin fragility-woolly hair-palmoplantar keratoderma syndrome 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.

Integrated Genetics/Laboratory Corporation of America RCV000038034 SCV000917312 benign not specified 2018-11-23 criteria provided, single submitter clinical testing Variant summary: DSP c.4065T>C alters a non-conserved nucleotide resulting in a synonymous change. 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 0.00083 in 276350 control chromosomes in the gnomAD database, including 1 homozygote. The observed variant frequency is approximately 80 fold of the estimated maximal expected allele frequency for a pathogenic variant in DSP causing Arrhythmia phenotype (1e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.4065T>C in individuals affected with Arrhythmia and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign (1x) / likely benign (2x). Based on the evidence outlined above, the variant was classified as benign.
