Invitae RCV000641767 SCV000763415 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2023-10-22 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 2341 of the DSP protein (p.Asp2341Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DSP-related conditions. ClinVar contains an entry for this variant (Variation ID: 191642). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV002362878 SCV002661991 uncertain significance Cardiovascular phenotype 2021-07-22 criteria provided, single submitter clinical testing The p.D2341N variant (also known as c.7021G>A), located in coding exon 24 of the DSP gene, results from a G to A substitution at nucleotide position 7021. The aspartic acid at codon 2341 is replaced by asparagine, an amino acid with highly similar properties. This alteration has been reported as a secondary cardiac variant in an exome cohort; however, clinical details are limited (Ng D et al. Circ Cardiovasc Genet, 2013 Aug;6:337-46). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
