About

Brugada syndrome (BrS) is the leading cause of sudden death in young Asian adults including Thailand. This syndrome may be hereditary and involve mutations in certain genes. Aim of the study is to identify the relationship between genetic variants and the diagnosis/clinical severity of patients with BrS.

Full description

This cohort study recruits BrS patients with confirmed Brugada type 1 ECG and healthy volunteers in Thailand. Data collection consists of demographic, clinical data, ECG and blood sample for genetic studies. Genotyping was done by whole genome sequencing and SNP array then compared between cases and controls. Each BrS patient will be followed up prospectively for symptoms and AICD shock. Subsequently, the study will analyze relationship between genetic variants and clinical data against clinical severity of BrS patients.
