Arrhythmogenic cardiomyopathy with wooly hair and keratoderma

A cardioectodermal syndrome that is often associated with the gene DSP, encoding desmoplakin. Desmoplakin is a member of the plakin family of cell adhesion molecules that are responsible for the formation and maintenance of desmosomes. Variation in DSP is associated with cardiomyopathic manifestations that include: (1) seemingly isolated arrhythmogenic right ventricle cardiomyopathy (ARVC) that is atypical and can show left ventricle dominance, or be present in the left and right ventricle simultaneously; and (2) dilated cardiomyopathy. Cutaneous phenotypes including wooly hair and/or keratoderma can present along with the cardiomyopathy, but are noted as less penetrant features.
