Abstract
The discovery of single nucleotide polymorphisms ( SNPs) is currently pursued with a tremendous effort. SNPs represent a rich source for molecular markers, since estimations predict six to seven million of these DNA variations in the human genome. A subset of these genetic variants is thought to have a pervasive impact on modern medicine, be it for the elucidation of differential pharmacological response or for the facilitated identification of genes involved in monogenetic and complex human diseases. Here we describe the overall process that leads to the set up of a SNP database. We describe a high-throughput sequencing assay for SNP discovery, automation of the dataflow from the DNA sequencer to the SNP analysis, and the tools to facilitate it. At the end of the process, a web-accessible interface collects the SNP information, which is processed in order to be written into the SNP database and to be available for end users who would like to select appropriate SNPs for their special screening needs.
