SCN5A Mutation Associated With Dilated Cardiomyopathy, Conduction Disorder, and Arrhythmia

Abstract excerpt

BACKGROUND: We studied a large family affected by an autosomal dominant cardiac conduction disorder associated with sinus node dysfunction, arrhythmia, and right and occasionally left ventricular dilatation and dysfunction. Previous linkage analysis mapped the disease phenotype to a 30-cM region on chromosome 3p22-p25 (CMD1E). This region also contains a locus for right ventricular cardiomyopathy (ARVD5) and the...
