Abstract

The dissection of complex diseases is one of the greatest challenges of human ge netics with important clinical and scientific applications. Traditionally, associations were sought between single genetic markers and disease. The availability of large scale SNP data makes it possible, for the first time, to study the predictive power of genotypes and haplotypes with respect to phenotype data. Here we present a novel method for predicting phenotype information from genotype data. The method is based on a support vector machine that employs new kernel functions for the similarity between genotypes or their underlying haplotypes. We demonstrate our approach on SNP data for the apolipoprotein gene cluster in baboons, predicting plasma lipid levels with significant success rates, and identifying associations that were not detected using extant approaches.
