markers, have been performed on both an initial dataset of 105 multigenerational pedigrees and a replication dataset with 157 multigenerational pedigrees. In a departure from GAW tradition, extensive new SNP genotyping was performed on DNA provided by COGA for the previously genotyped families. Illumina, Affymetrix, and the Center for Inherited Disease Research (CIDR) performed this work and donated these data to GAW14 and to COGA. A subset of 143 informative families, selected from the initial and replication datasets, were genotyped for these SNP markers. A total of 1,350 COGA samples were genotyped by Affymetrix for 11,560 SNPs from their GeneChip Mapping 10 K array and by Illumina for their Linkage III Panel containing 4,763 SNP markers. These data are described in detail in Edenberg et al. [1].
