Invitae | RCV001042593 | SCV001206285 | uncertain significance | Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 | 2023-11-22 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 671 of the DSP protein (p.Glu671Gly). This variant is present in population databases (rs758530970, gnomAD 0.0009%). 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: 840565). 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. |

RCV001187059 | SCV001353718 | uncertain significance | Cardiomyopathy | 2023-12-05 | criteria provided, single submitter | clinical testing | This missense variant replaces glutamic acid with glycine at codon 671 of the DSP protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |
Ambry Genetics | RCV003160289 | SCV003855695 | uncertain significance | Cardiovascular phenotype | 2023-01-23 | criteria provided, single submitter | clinical testing | The p.E671G variant (also known as c.2012A>G), located in coding exon 15 of the DSP gene, results from an A to G substitution at nucleotide position 2012. The glutamic acid at codon 671 is replaced by glycine, an amino acid with similar properties. 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. |
