Mutations in genes encoding for desmosomal components are associated with a broad spectrum of phenotypes comprising skin and hair abnormalities and account for 45–50% of cases of arrhythmogenic right ventricular cardiomyopathy. Today, more than 120 dominant and recessive desmoplakin (DSP) gene mutations have been reported to be associated with skin, hair and/or heart defects. Here we report on 3 cases with yet unreported DSP mutations, c.7566_7567delAAinsC, p.R2522Sfs*39, c.7756C>T, p.R2586*, c.2131_2132delAG and c.1067C>A, p.T356K, that were associated with variable woolly hair or hypotrichosis, palmoplantar keratoderma, and cardiac manifestations. In addition, we review and summarise the clinical features and DSP mutations of the patients described in the literature, which illustrates the complexity of this group of disorders and of their genotype-phenotype correlations, which cannot be easily predicted. Early diagnosis is crucial and cardiac examinations have to be performed on a regular basis.
