RCV001299043 | SCV001488119 | uncertain significance | Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 | 2022-09-12 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 979 of the DSP protein (p.Pro979Arg). 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: 1002594). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest 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 | RCV003166678 | SCV003867598 | uncertain significance | Cardiovascular phenotype | 2023-01-28 | criteria provided, single submitter | clinical testing | The p.P979R variant (also known as c.2936C>G), located in coding exon 21 of the DSP gene, results from a C to G substitution at nucleotide position 2936. The proline at codon 979 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
