Key result
SCN5A mutations are associated with multiple overlapping phenotypes, including LQT3, Brugada syndrome, and Lev-Lenegre syndrome, suggesting a unified sodium channel syndrome.

Implication
Hypothesis-generating for unifying SCN5A phenotypes as a sodium channel syndrome; should not yet change diagnostic practice.

Population
Patients with SCN5A mutations associated with cardiac arrhythmias, including LQT3, Brugada syndrome, and Lev-Lenegre syndrome
The review proposes reclassifying LQT3, Brugada syndrome, and Lev-Lenegre syndrome as a unified 'sodium channel syndrome' due to overlapping clinical presentations from SCN5A mutations.
Cite This Study
Napolitano et al. (2003) conducted a review in Cardiac Sodium Channel Diseases. SCN5A mutations are associated with multiple overlapping phenotypes, including LQT3, Brugada syndrome, and Lev-Lenegre syndrome, suggesting a unified sodium channel syndrome.
