ZFHX3 and atrial fibrillation: Together with our earlier reports, we show that among the 15 GWAS loci for AF reported in the European ancestry populations and Japanese population, seven loci (PITX2c, ZFHX3, CAV1, NEURL, GJA1, TBX5 and CUX2 loci) also confer a significant risk of AF in the Chinese Han population.
