Abstract:
We report here 20 single-nucleotide polymorphisms (SNPs), including 15 novel ones, in six genes that are considered to be candidates for long QT syndrome (LQTS): 2 SNPs in KCNB1, 3 in KCND3, 3 in KCNJ11, 7 in ABCC9, 3 in ADRB1, and 2 in SLC18A2. We also examined their allelic frequencies in a Japanese sample population of LQTS-affected and nonaffected individuals. These data will be useful for genetic association studies designed to investigate acquired arrhythmias.
