Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_004415.4(DSP):c.3923G>A(p.Arg1308Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000273 in 1,613,998 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1308W) has been classified as Uncertain significance.

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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: The c.3923G>A (p.Arg1308Gln) in the DSP gene is a missense change that involves the alteration of a non- conserved nucleotide and 5/5 in silico tools predict benign outcome. The variant was observed in the large and broad cohorts of the ExAC project at an allele frequency of 0.001212 (146/ 120504 chrs tested), predominantly in individuals of East Asian descent (0.01648; 142/ 8618 chrs, including 1 homozygotes). The latter frequency exceeds the maximal expected allele frequency for a pathogenic variant in this gene (0.00001). Lastly, several reputable databases/diagnostic centers classified the variant of interest as Benign/Likely Benign. Taking together, the variant was classified as Benign. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
