Naxos syndrome

Naxos syndrome
Classification and external resources
Cutaneous phenotype of Naxos disease: woolly hair (A), palmar (B) and plantar (C) keratoses.
OMIM	601214

Naxos syndrome (also known as "Diffuse non-epidermolytic palmoplantar keratoderma with woolly hair and cardiomyopathy,"^[1] "Diffuse palmoplantar keratoderma with woolly hair and arrythmogenic right ventricular cardiomyopathy firstly described in Naxos island by Dr Nikos Protonotarios,"^[1] and "Naxos disease"^[1]) is a cutaneous condition characterized by a palmoplantar keratoderma.^[1] The prevalence of the syndrome is about 1 person in 1000 in the Hellenic islands.

It has been associated with mutations in the genes encoding desmoplakin and plakoglobin.^[2]
