Abstract excerpt
Recent studies have demonstrated an association between mutations in CACNA1c or CACNB2b and Brugada syndrome (BrS). Previously described mutations all caused a loss of function secondary to a reduction of peak calcium current (I(Ca)). We describe a novel CACNB2b mutation associated with BrS in which loss of function is caused by accelerated inactivation of I(Ca). The proband, a 32 year old male, displayed a Type...
