Definition
A syndrome that is characterized by woolly hair, palmoplantar keratoderma and dilated cardiomyopathy principally affecting the left ventricle.
Epidemiology
Only a few cases have been reported, all involving patients from Ecuador, India or Turkey.
Clinical description
The woolly hair is present at birth and the palmoplantar keratoderma appears during the first year of life. The cardiac anomaly presents during childhood and is marked by dilation of the left ventricle accompanied by alterations in muscle contractility. The dilated cardiomyopathy may lead to life-threatening congestive heart failure.
Etiology
The syndrome is transmitted as an autosomal recessive trait and is caused by mutations in the DSP gene (6p24) encoding desmoplakin, a protein involved in cell adhesion.
Differential diagnosis
The syndrome is similar to Naxos disease (see this term).
