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
