Background— Plasma levels of coagulation factors VII (FVII), VIII (FVIII), and von Willebrand factor (vWF) influence risk of hemorrhage and thrombosis. We conducted genome-wide association studies to identify new loci associated with plasma levels.

Methods and Results— The setting of the study included 5 community-based studies for discovery comprising 23 608 European-ancestry participants: Atherosclerosis Risk In Communities Study, Cardiovascular Health Study, British 1958 Birth Cohort, Framingham Heart Study, and Rotterdam Study. All subjects had genome-wide single-nucleotide polymorphism (SNP) scans and at least 1 phenotype measured: FVII activity/antigen, FVIII activity, and vWF antigen. Each study used its genotype data to impute to HapMap SNPs and independently conducted association analyses of hemostasis measures using an additive genetic model. Study findings were combined by meta-analysis. Replication was conducted in 7604 participants not in the discovery cohort. For FVII, 305 SNPs exceeded the genome-wide significance threshold of 5.0x10–8 and comprised 5 loci on 5 chromosomes: 2p23 (smallest P value 6.2x10–24), 4q25 (3.6x10–12), 11q12 (2.0x10–10), 13q34 (9.0x10–259), and 20q11.2 (5.7x10–37). Loci were within or near genes, including 4 new candidate genes and F7 (13q34). For vWF, 400 SNPs exceeded the threshold and marked 8 loci on 6 chromosomes: 6q24 (1.2x10–22), 8p21 (1.3x10–16), 9q34 (<5.0x10–324), 12p13 (1.7x10–32), 12q23 (7.3x10–10), 12q24.3 (3.8x10–11), 14q32 (2.3x10–10), and 19p13.2 (1.3x10–9). All loci were within genes, including 6 new candidate genes, as well as ABO (9q34) and VWF (12p13). For FVIII, 5 loci were identified and overlapped vWF findings. Nine of the 10 new findings were replicated.

Conclusions— New genetic associations were discovered outside previously known biological pathways and may point to novel prevention and treatment targets of hemostasis disorders.

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=3.9x10–8). The QT interval was associated with the earlier reported NOS1AP gene (rs2880058, P=2.00x10–10) and with a region on chromosome 13 (rs2478333, P=4.34x10–8), which is 100 kb from the closest known transcript LOC730174 and has previously not been associated with the length of the QT interval.

Conclusion— Our results suggested an association between the RR interval and GPR133 and confirmed an association between the QT interval and NOS1AP.
