Brugada Gene Identified

It might be fair game for next year's EP board certification exam: the Brugada Syndrome gene:
Using positional cloning and gene sequencing on a family affected with Brugada syndrome, Dr. London and colleagues identified a mutation in a previously unstudied gene, GPD1-L, on chromosome 3p24. This mutation impairs the heart’s natural electrical ability to beat in a coordinated manner and maintain a stable rhythm. To date, only ion channel genes had been shown to cause Brugada syndrome.
