CHICAGO--After adding 60,000 newly identified single-nucleotide polymorphisms last week to the 40,000 it had already released to the public domain, the SNP Consortium said it had generated twice the number of SNPs it had hoped to during its first year. Arthur Holden, chairman of the pharmaceutical-industry-funded project, said it is now on an accelerated schedule to complete a more extensive SNP map than originally planned.
