Author Information
Author(s): Nikos Protonotarios, Adalena Tsatsopoulou
Primary Institution: Yannis Protonotarios Medical Center
Hypothesis
Naxos disease is a recessive form of arrhythmogenic right ventricular dysplasia/cardiomyopathy characterized by specific genetic mutations.
Conclusion
Naxos disease is associated with significant cardiac abnormalities and a risk of sudden death, particularly in younger patients.
Supporting Evidence
- Naxos disease has a prevalence of 1:1000 in Hellenic islands.
- Genetic studies identified mutations in plakoglobin and desmoplakin as causes of Naxos disease.
- Patients typically present with woolly hair and palmoplantar keratoderma from birth.
- Electrocardiographic abnormalities are present in over 90% of patients during adolescence.
- The annual sudden death mortality rate in patients with Naxos disease is 2.3%.
Takeaway
Naxos disease is a heart condition that can cause serious problems, especially for young people, and is linked to certain genetic changes.
Methodology
The study involved genetic analysis and clinical observation of patients with Naxos disease.
Limitations
The study may not cover all cases of Naxos disease, especially those outside the reported regions.
Participant Demographics
Patients primarily from Greece, Turkey, and other Hellenic islands, with some cases reported in India and Ecuador.
