We downloaded the dataset of 11 811 594 human SNPs and their annotations from the dbSNP (build 126) (3) and Ensembl (release 42) (4) databases. We also downloaded a list of 38 550 human genes along with their primary information such as gene symbol, alias names, chromosomal location and gene type from NCBI Entrez Gene (downloaded 12 December 2006).
