This variant has not been reported in the literature in individuals affected with DSG2-related conditions. This variant is present in population databases (rs758822081, gnomAD 0.02%). This sequence change creates a premature translational stop signal (p.Arg1049Phefs*2) in the DSG2 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 70 amino acid(s) of the DSG2 protein. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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 | RCV002323825 | SCV002609044 | uncertain significance | Cardiovascular phenotype | 2024-02-26 | criteria provided, single submitter | clinical testing | The c.3144_3147delAAGA variant, located in coding exon 15 of the DSG2 gene, results from a deletion of 4 nucleotides at nucleotide positions 3144 to 3147, causing a translational frameshift with a predicted alternate stop codon (p.R1049Ffs*2). This alteration has been reported in association with dilated cardiomyopathy (DCM) (Yang Q et al. J Am Heart Assoc, 2022 Oct;11:e025257). This alteration occurs at the 3' terminus of theDSG2 gene, is not expected to trigger nonsense-mediated mRNAdecay, and only impacts the last 70 amino acids of the protein. The exact functional effect of this alteration is unknown. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
