The genotypes of 35,528 persons were used in this study. These individuals are participants in a large number of on-going genome-wide association studies being conducted in-house. All participants signed an informed consent. Four different Illumina chip-based arrays were used over the course of data collection, with a common core of over 300,000 SNPs. For inclusion in the study, the genotype yield of a person on that person's chip had to exceed 98% (1561 individuals were excluded due to this criterion).
