As a medical professional with a focus on cardiology, I can provide you with an informed explanation of the cause of Brugada syndrome.
Brugada syndrome is a genetic disorder that affects the heart's electrical system. It is characterized by abnormal electrocardiogram (ECG) findings and an increased risk of sudden death due to a specific type of abnormal heart rhythm called ventricular fibrillation. The primary cause of Brugada syndrome is a mutation in the genes responsible for the normal functioning of the heart's electrical system. The most common gene associated with this condition is the SCN5A gene, which encodes for a protein that forms part of the sodium channels in the heart cells. Mutations in this gene can lead to a disruption in the flow of sodium ions, which is crucial for the proper electrical signaling of the heart.
Other genes have also been implicated in the development of Brugada syndrome, and it's important to note that not all cases are due to genetic mutations. Environmental factors and certain medications can also trigger the symptoms of Brugada syndrome in susceptible individuals.
To summarize, Brugada syndrome is caused by a combination of genetic mutations and, in some cases, environmental or pharmacological triggers that affect the heart's electrical activity.

Mutations in the SCN5A gene alter the structure or function of the channel, which reduces the flow of sodium ions into cells. A disruption in ion transport alters the way the heart beats, leading to the abnormal heart rhythm characteristic of Brugada syndrome. Mutations in other genes can also cause Brugada syndrome.
