Information technology tools for efficient SNP studies.

Abstract

We are currently facing a new era of studies involving single nucleotide polymorphisms (SNPs). This increased attention is stimulated by interest in individual differences in disease susceptibility as well as individual responses to drug treatment and the falling cost of genotyping. This review is a guide to the numerous public data repositories and Information Technology (IT) tools that may aid planning, preparation, running and analysis of studies involving SNPs. I will also highlight areas where researchers will have to resort to home-made IT solutions. Unfortunately, both information and IT tools are scattered throughout the internet and a lack of data exchange conventions can hamper the efficient use of these existing resources. This can lead to situations where the planning, preparation and analysis of a SNP study can actually cost more than the actual genotyping. We propose that only a customizable backbone IT infrastructure for SNP studies can help reduce costs associated with SNP data handling and tool launching.
