Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_004415.4(DSP):c.6557T>G(p.Leu2186Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. L2186L) has been classified as Likely benign.

Genes affected
DSP (HGNC:3052): (desmoplakin) This gene encodes a protein that anchors intermediate filaments to desmosomal plaques and forms an obligate component of functional desmosomes. Mutations in this gene are the cause of several cardiomyopathies and keratodermas, including skin fragility-woolly hair syndrome. Alternative splicing results in multiple transcript variants.

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jan 02, 2015 | The p.Leu2186Arg variant in DSP has not been previously reported in individuals with cardiomyopathy or in large population studies. Computational prediction too ls and conservation analysis suggest that this variant may impact the protein, t hough this information is not predictive enough to determine pathogenicity. In s ummary, the clinical significance of the p.Leu2186Arg variant is uncertain. - |
