OBJECTIVES The aim of this study was to test the hypothesis that 2 common polymorphisms in the chromosome 4q25 region that have been associated with atrial fibrillation (AF) contribute to the variable penetrance of familial AF. BACKGROUND Although mutations in ion channels, gap junction proteins, and signaling molecules have been described for Mendelian(More)
BACKGROUND Mutations in a novel GTPase gene SPG3A cause an autosomal dominant hereditary spastic paraplegia linked to chromosome 14q (SPG3), which accounts for approximately 10% to 15% of all autosomal dominant hereditary spastic paraplegia cases. The mutational spectrum of the SPG3A gene and the phenotype/genotype correlations have not yet been(More)
