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.

DSP-AS1 (HGNC:56039): (DSP antisense RNA 1)

ACMG classification

Our verdict: Likely_benign. The variant received -5 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.61).
• BP6: Variant 6-7542096-G-T is Benign according to our data. Variant chr6-7542096-G-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 179633.We mark this variant Likely_benign, oryginal submission is: [Conflicting_classifications_of_pathogenicity].

Variant classified as Uncertain Significance - Favor Benign. The 170+11G>T varia nt in DSP has not been previously reported in individuals with cardiomyopathy an d data from large population studies is insufficient to assess the frequency of this variant. Additional information is needed to fully assess the clinical sign ificance of the 170+11G>T variant. -
