SNAP finds proxy SNPs based on linkage disequilibrium, physical distance and/or membership in selected commercial genotyping arrays. Pair-wise linkage disequilibrium is pre-calculated based on phased genotype data from the International HapMap Project and the 1000 Genomes Project. Information about the genotyping arrays is based on data published by the vendors.
