All of Us Research Program, National Institutes of Health RCV004016301 SCV004830929 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma 2023-06-26 criteria provided, single submitter clinical testing This missense variant replaces glutamic acid with glutamine at codon 1898 of the DSP protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual who experienced an idiopathic ventricular fibrillation event (PMID: 29032884). 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.
Labcorp Genetics (formerly Invitae), Labcorp RCV005220847 SCV005865421 uncertain significance Arrhythmogenic cardiomyopathy with wooly hair and keratoderma; Arrhythmogenic right ventricular dysplasia 8 2024-09-03 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glutamine, which is neutral and polar, at codon 1898 of the DSP protein (p.Glu1898Gln). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with idiopathic ventricular fibrillation (PMID: 29032884). 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.
