The International HapMap Project

John W. Belmont, +145 more
- 18 Dec 2003 - 
TL;DR: The HapMap will allow the discovery of sequence variants that affect common disease, will facilitate development of diagnostic tools, and will enhance the ability to choose targets for therapeutic intervention.
Journal ArticleDOI

A second generation human haplotype map of over 3.1 million SNPs

Kelly A. Frazer, +237 more
- 18 Oct 2007 - 
TL;DR: The Phase II HapMap is described, which characterizes over 3.1 million human single nucleotide polymorphisms genotyped in 270 individuals from four geographically diverse populations and includes 25–35% of common SNP variation in the populations surveyed, and increased differentiation at non-synonymous, compared to synonymous, SNPs is demonstrated.
Journal ArticleDOI

Genome-wide detection and characterization of positive selection in human populations

Pardis C. Sabeti, +258 more
- 18 Oct 2007 - 
TL;DR: ‘Long-range haplotype’ methods, which were developed to identify alleles segregating in a population that have undergone recent selection, and new methods that are based on cross-population comparisons to discover alleles that have swept to near-fixation within a population are developed.
Journal ArticleDOI

Rapid identification of somatic mutations in colorectal and breast cancer tissues using mismatch repair detection (MRD).

TL;DR: A novel approach to high‐throughput mutation screening using small amounts of starting material is presented and a mutation spectrum across 30 genes in a large cohort of breast and colorectal cancers is revealed.
Journal ArticleDOI

Large-scale characterization of public database SNPs causing non-synonymous changes in three ethnic groups

TL;DR: This work genotyped approximately 28,000 single nucleotide polymorphisms in three ethnic populations and ten primate species and finds evidence that selection may be acting in concert on classes of genes.
