We set out to identify common genetic determinants of the length of the RR and QT intervals in 2325 individuals from isolated European populations.
We analyzed the heart rate at rest, measured as the RR interval, and the length of the corrected QT interval for association with 318 237 single-nucleotide polymorphisms. The RR interval was associated with common variants within GPR133, a G-protein-coupled receptor (rs885389, P=3.9 x 10(-8)). The QT interval was associated with the earlier reported NOS1AP gene (rs2880058, P=2.00 x 10(-10)) and with a region on chromosome 13 (rs2478333, P=4.34 x 10(-8)), which is 100 kb from the closest known transcript LOC730174 and has previously not been associated with the length of the QT interval.
Our results suggested an association between the RR interval and GPR133 and confirmed an association between the QT interval and NOS1AP.
我们着手在来自孤立欧洲人群的2325名个体中确定RR间期和QT间期长度的常见遗传决定因素。
我们分析了静息心率(以RR间期衡量)以及校正QT间期的长度与318237个单核苷酸多态性的关联。RR间期与G蛋白偶联受体GPR133内的常见变异相关(rs885389,P = 3.9×10⁻⁸)。QT间期与先前报道的NOS1AP基因(rs2880058,P = 2.00×10⁻¹⁰)以及13号染色体上的一个区域(rs2478333,P = 4.34×10⁻⁸)相关,该区域距离最近已知的转录本LOC730174有100 kb,且此前未与QT间期长度相关联。
我们的结果表明RR间期与GPR133之间存在关联,并证实了QT间期与NOS1AP之间存在关联。
