| Invitae | RCV000641792 | SCV000763441 | uncertain significance | Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 | 2021-06-01 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with DSP-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with threonine at codon 461 of the DSP protein (p.Ile461Thr). The isoleucine residue is highly conserved and there is a moderate physicochemical difference between isoleucine and threonine. |

RCV001270768 | SCV001451520 | uncertain significance | Arrhythmogenic right ventricular dysplasia 8 | 2019-03-20 | criteria provided, single submitter | clinical testing | The DSP c.1382T>C (p.Ile461Thr) missense variant is located in the SH3 desmosome binding domain. A literature search was performed for the gene, cDNA, and amino acid change. No publications were found based on this search. This variant is not found in the Genome Aggregation Database in a region of good sequencing coverage, so the variant is presumed to be rare. Based on the limited evidence, the p.Ile461Thr variant is classified as a variant of uncertain significance for arrhythmogenic right ventricular cardiomyopathy. |
