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.

The variant allele was found at a frequency of 0.00024 in 246768 control chromosomes, predominantly at a frequency of 0.0012 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 6 fold of the estimated maximal expected allele frequency for a pathogenic variant in DSP causing Arrhythmogenic Right Ventricular Dysplasia/Cardiomyopathy phenotype (0.0002). c.8508_8519delATCTCGCTCCGG has been reported in the literature in at least 1 individual affected with decreased left ventricular ejection fraction (example, Carrick_2024). It was also observed in at least 1 healthy control individual (example, Kapplinger_2011). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 39011630, 36437915, 36212137, 25445213, 21636032). ClinVar contains an entry for this variant (Variation ID: 44975). Based on the evidence outlined above, the variant was classified as benign.

Ambry Genetics	RCV002408516	SCV002675433	likely benign	Cardiovascular phenotype	2018-09-07	criteria provided, single submitter	clinical testing	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.
