Background: We set out to identify common genetic determinants of the length of the RR and QT intervals in 2325 individuals from isolated European populations.

Methods And Results: 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.

Conclusions: Our results suggested an association between the RR interval and GPR133 and confirmed an association between the QT interval and NOS1AP.
