Following the November 2001 publication in Science of a SNP map of human chromosome 21, Perlegen scientists say they sequenced 50 complete haploid genomes, yielding more than 1.7 million SNPs. More ...

The data are then analyzed to determine the SNP genotype at every SNP position for a given individual. Using this approach, scientists can simultaneously determine whether certain SNPs or a ...

The International SNP Map Working Group has compiled a map of 1.4 million single-nucleotide polymorphisms. What fraction of all human sequence variation is captured in this collection, and what ...

The first use of SNP microarrays in a large autism study was by the Autism Genome Project, who used Affymetrix 10K SNP microarray data to perform high-resolution linkage analysis in over 1000 ...
