Abstract

BACKGROUND: Brugada syndrome (BrS) remains genetically heterogeneous and is associated with slowed cardiac conduction. OBJECTIVES: We aimed to identify genetic variation in BrS cases at loci associated with QRS duration. METHODS AND RESULTS: A multi-centre study sequenced 7 candidate genes (SCN10A, HAND1, PLN, CASQ2, TKT, TBΧ3 and ΤΒΧ5) in 156 Caucasian SCN5A mutation-negative BrS patients (80% male; mean age 48) with symptoms (64%) and/or a family history of sudden death (47%) or BrS (18%). Forty-nine variants were identified: 18 were rare (MAF
