Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Feb 18, 2015 | p.Ser2843_Arg2846del in exon 24 of DSP: This variant is not expected to have cli nical significance because it has been identified in 0.4% (50/11494) of Latino c hromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute .org). This in-frame deletion of four amino acids occurs within a region of repe ating amino acids. It can result from several different DNA deletions, and is pr esent in mammals (dolphin, opossum, and platypus) and other evolutionarily dista nt species. - |
Benign, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Jul 08, 2019 | Variant summary: DSP c.8508_8519del12 (p.Ser2843_Arg2846del) results in an in-frame deletion that is predicted to remove four amino acids from a repetitive region at the C-terminus of the protein (of note, this protein level change can be a result of several different DNA deletions). The variant allele was found at a frequency of 0.0003 in 278122 control chromosomes, predominantly at a frequency of 0.0015 within the African or African-American subpopulation in the gnomAD database. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 7.5 fold of the estimated maximal expected allele frequency for a pathogenic variant in DSP causing Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy phenotype (0.0002), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. Though the variant has been reported in the literature in one individual affected with Arrhythmogenic Right Ventricular Cardiomyopathy (Green_2014), it was also described in a healthy control (Kapplinger_2011). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three ClinVar submitters (evaluation after 2014) classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign. - |

Cardiovascular phenotype Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 07, 2018 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
