房颤(Atrial Fibrillation, AF) 房颤是临床最常见的持续性心律失常 据统计,人群患病率接近1%,在美国影响300万人 我国患者高达1300万 危害极大,大大提高患者死亡率和脑中风的发生率。 Genetic Loci and Genes for AF Genetic Loci and Genes for AF Genetic Component of Complex AF 1. Framingham Heart Study (2,234 offsprings): Risk ratio (RR) = 1.85 for offsprings if at least one parent has AF OR = 3.23 with study participants younger than 75 years or to 3.17 when offsprings with overt heart disease were excluded. 2. Icelandic Study (5,269 AF patients and 10,000 controls ): RR = 1.77 for the first-degree relatives = 1.36 for the second-degree relative = 4.67 for first-degree relatives under the age of 60 years 3. MGH Study (110 patients with lone AF ) RR = 8.1 for sons, 9.5 for daughters, 70 for brothers, 34 for sisters, 4 for mothers, and 2 for fathers17 Association of SNPs on Chromosome 16q22 with AF Variants in ZFHX3 are associated with atrial fibrillation in individuals of European ancestry.

National Heart, Lung, and Blood Institutes Framingham Heart Study ; replicated this association in an independent cohort from the German AF Network A sequence variant in ZFHX3 on 16q22 associates with atrial fibrillation and ischemic stroke.
