Naxos disease[1] (also known as "diffuse non-epidermolytic palmoplantar keratoderma with woolly hair and cardiomyopathy"[1] or "diffuse palmoplantar keratoderma with woolly hair and arrhythmogenic right ventricular cardiomyopathy", first described on the island of Naxos by Nikos Protonotarios[1]) is a cutaneous condition characterized by a palmoplantar keratoderma.[1] The prevalence of the syndrome is up to 1 in every 1000 people in the Greek islands.[2]
It has been associated with mutations in the genes encoding the proteins desmoplakin, plakoglobin, desmocollin-2, and SRC-interacting protein (SIP).[3][4] Naxos disease has the same cutaneous phenotype as the Carvajal syndrome.[2]
Symptoms
Between 80 and 99% of those with Naxos disease will display some of the following symptoms:
- Disease of the heart muscle
- Thickening of palms and soles
- Sudden increased heart rate
- Dizzy spells
- Kinked hair[5]
