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 submitterclinical testingAmbry GeneticsDec 17, 2021The c.6812A>C (p.K2271T) alteration is located in exon 24 (coding exon 24) of the DSP gene. This alteration results from a A to C substitution at nucleotide position 6812, causing the lysine (K) at amino acid position 2271 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
