Cheek Swab Test Can Detect Deadly Heart Condition in Children Years Before Diagnosis

What is Arrhythmogenic Cardiomyopathy (ACM)?
Arrhythmogenic cardiomyopathy (ACM) is a genetic heart condition that causes abnormalities in the proteins between heart cells. These abnormalities lead to problems with the heart’s structure and electrical activity. ACM can develop and strike without warning, making early detection crucial.
ACM is responsible for more then 10% of sudden cardiac deaths in children. The condition often goes undiagnosed until symptoms appear, which can be life-threatening. Traditional diagnostic methods may not identify the condition until years after the initial protein abnormalities develop.
How Does the Cheek Swab Test Work?
Researchers have discovered that abnormalities in the proteins associated with ACM can also be detected in the lining of the cheeks. This breakthrough led to the development of a simple, two-minute cheek swab test.
The test works by analyzing cells collected from the cheek swab for specific protein markers indicative of ACM. This allows doctors to identify children at risk up to five years before they might or else be diagnosed.
The Research and Trial
The test was trialled in 51 children between three months and 18 years old who had a known genetic risk of ACM. these children were given cheek swabs every three to six months over a seven-year period.
Of the 51 children monitored, 10 went on to develop ACM. Importantly, eight of those 10 children showed abnormalities in thier cheek swab results *before* they were diagnosed with the condition. This demonstrates the test’s potential for early detection.
Understanding the Genetic Risk
ACM is typically a genetic condition, meaning its passed down through families. If a child has a parent or close relative with ACM, they are at a higher risk of developing the condition themselves. However, genetic testing can sometimes be inconclusive, and the condition can also arise from spontaneous genetic mutations.
Identifying children with a genetic predisposition is the first step in preventative care. The cheek swab test provides a non-invasive way to monitor these children and detect early signs of ACM.
Symptoms of ACM
Symptoms of ACM can vary widely and may not appear until the condition is advanced. Common symptoms include:
- Palpitations (feeling a fluttering or racing heartbeat)
- Dizziness or fainting
- Shortness of breath
- Chest pain
- Fatigue
Though, some individuals with ACM may experience no symptoms at all, making early detection even more critical.
