HapMap associated_with SNP

Phase I of the project genotyped 1.3 million SNPs; Phase II HapMap characterized over 3.1 million SNPs.

58,819 autosomal SNPs from the ILMN100K panel overlap with the HapMap

resulting in ≈1,000 SNPs for each region for the panel of 120 HapMap chromosomes

using publicly available online databases such as ... HapMap ... to identify all known SNPs

The selection of SNPs is mostly based on the distribution of linkage disequilibrium across the genome, as identified by the HapMap project.

HapMap project ... has validated around 4 million SNPs including 2.8 million of the estimated 10 million common SNPs in major world populations

LD structures calculated from HapMap enable imputation (prediction) of ungenotyped SNPs.
