What is Naxos Disease?

Naxos Disease is a rare genetic disorder that affects the heart and skin. It is named after the Greek island of Naxos, where it was first identified. This condition is part of a group of diseases known as arrhythmogenic right ventricular cardiomyopathy (ARVC), which primarily impacts the heart muscle. Let's explore some intriguing facts about this rare condition.

Genetic Origin: Naxos Disease is inherited in an autosomal recessive manner. This means both parents must carry a copy of the mutated gene for their child to be affected.
Plakoglobin Mutation: The disease is caused by mutations in the plakoglobin gene, which plays a crucial role in cell adhesion, especially in heart and skin cells.
Heart Complications: Individuals with Naxos Disease often experience arrhythmias, which are irregular heartbeats that can lead to sudden cardiac arrest.
Skin and Hair Symptoms: Affected individuals typically have woolly hair and thickened skin on the palms and soles, known as palmoplantar keratoderma.
First Identified in Greece: The disease was first described in families from the Greek island of Naxos, giving it its name.

How Does Naxos Disease Affect the Heart?

The heart is significantly impacted by Naxos Disease, leading to various complications. Understanding these effects can help in managing the condition better.

Right Ventricle Focus: The disease primarily affects the right ventricle of the heart, leading to its enlargement and dysfunction.
Fatty Replacement: In Naxos Disease, heart muscle cells are replaced by fatty and fibrous tissue, weakening the heart's ability to pump blood effectively.
Risk of Heart Failure: Over time, the damage to the heart muscle can lead to heart failure, a condition where the heart cannot pump enough blood to meet the body's needs.
Exercise Risks: Physical exertion can exacerbate heart problems in individuals with Naxos Disease, increasing the risk of arrhythmias and cardiac arrest.
Early Onset: Symptoms related to the heart often begin in adolescence or early adulthood, making early diagnosis crucial.

What Are the Skin and Hair Manifestations?

Naxos Disease is not just about heart issues. It also presents distinct skin and hair symptoms that can help in its diagnosis.

Woolly Hair: Affected individuals have tightly curled, woolly hair from birth, which is a hallmark of the disease.
Palmoplantar Keratoderma: Thickened skin on the palms and soles develops in early childhood, often before heart symptoms appear.
Skin Changes Over Time: The skin thickening tends to worsen with age, becoming more pronounced as the individual grows older.
Diagnostic Clue: The combination of woolly hair and palmoplantar keratoderma is a key diagnostic clue for Naxos Disease.
Genetic Testing: Confirming the diagnosis often involves genetic testing to identify mutations in the plakoglobin gene.
