Single Nucleotide Polymorphisms: Big Pharma Hedges its Bets
Eugene Russo | Jul 18, 1999 | 7 min read
SNP CENTRAL: A genetics researcher takes to the bench at the Wellcome Trust's Sanger Centre in Cambridge, England. The sequencing center and its London sponsor provided key leadership in the SNP Consortium, a public-private venture to find and map 300,000 single nucleotide polymorphisms. The Wellcome Trust helped entice 10 pharmaceutical firms to join the consortium by putting up $14 million of the project's estimated $45 million price tag. The Sanger Centre will provide much of the radiation h

SNPs as Windows on Evolution
Ricki Lewis | Jan 6, 2002 | 7 min read
Single nucleotide polymorphisms--variants in DNA sequences better known as SNPs and pronounced snips--provide a shortcut to comparing genes and genomes within and among species. The need to study SNPs has spawned a number of companies aimed at matching SNP patterns to disease risks. A few other organizations, however, are taking a broader view: mining SNPs for clues to human diversity and evolution. Association studies that correlate SNP patterns to disease risks are straightforward. Clues to

Gonorrhea-Blocking Mutation Also Protects Against Alzheimer’s: Study
Holly Barker, PhD | Aug 5, 2022 | 4 min read
Research traces the evolution of a gene variant that reduces the risk of Alzheimer’s disease, finding that it originally evolved in response to infectious bacteria.
Mouse Genomes Catalogued

Researchers have sequenced the genomes of 17 different mouse strains, boosting research into the genetic basis of phenotypic variation, disease, and evolution.
ABI Poised to Break the SNP Genotyping Speed Barrier?
Deborah Stull | Mar 23, 2003 | 2 min read
Courtesy of Applied Biosystems Single nucleotide polymorphisms--variations at specific nucleotide positions in the genome sequences of two individuals--are perhaps the most common form of genetic diversity; it is estimated that 3-10 million SNPs are present in the human genome. Researchers use these markers to map disease genes, and in the burgeoning field of pharmacogenomics (personalized medicine). Such research necessarily requires the ability to genotype on a grand scale, but until recent
Whole-Genome SNP Genotyping

Clockwise from top left: images courtesy of Affymetrix, Illumina, Sequenom and Illumina Take any two individuals, sequence and compare their genomic DNA, and you'll find that the vast majority (about 99.9%) of the sequences are identical. In the remaining 0.1% lie differences in disease susceptibility, environmental response, and drug metabolism. Researchers are understandably keen to dissect these variations, most of which take the form of single-nucleotide polymorphisms (SNPs). A SNP (pron

Large Scientific Collaborations Aim to Complete Human Genome
Brianna Chrisman and Jordan Eizenga | Sep 1, 2022 | 10+ min read
Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.
