Markers from the exome chip and genome-wide chip were combined into an integrated panel of 629,573 polymorphic SNPs. There were 84,678,352 overlapping genotypes between the arrays in this sample (11,792 overlapping SNPs times 7181 individuals; we include the MZ co-twins in these numbers). Of these, 84,654,782 were non-missing on both chips (99.9722%). Of non-missing variants, 84,654,329 (99.9995%) were concordant. The 453 discordant genotypes were set to missing.
