摘要	Background/Aims: We consider the situation that multiple genetic variants are underlying a heritable trait and assume that each contributes to the trait only to a small degree. The aim is to develop a statistical test for disease association of these multiple variants. Methods: We expect that p values resulting from a genome-wide case-control association analysis will fall into two classes: those reflecting true association and those occurring randomly in the interval from 0 to 1. We develop a partition test to find the set of smallest p values deviating most from the number of p values expected under randomness. Results: Power calculations demonstrate the superiority of our partition test over conventional SNP-by-SNP analyses. Applications of the partition test to six published datasets show that our test is particularly suitable when multiple SNPs appear to contribute to a trait, and furnished more significant results than a well-known procedure to estimate the false discovery rate. Conclusions: Our partition test also furnishes an estimate of the number of functional SNPs underlying disease and can be highly significant, while single-locus tests may be far from significant.

项目简介	Support from China NSFC grant No. 30730057 is gratefully acknowledged. This study used data from the SNP Database at the NINDS Human Genetics Resource Center DNA and Cell Line Repository (http://ccr.coriell.org/ninds), as well as clinical data. The original genotyping was performed in the laboratories of Drs. Singleton and Hardy, (NIA, LNG), Bethesda, Md., USA. Funding support for development of a novel analysis methods was provided by the Rockefeller University, based on a subcontract from the Albert Einstein College of Medicine, and the genotyping of samples was provided through the Genetic Association Information Network (GAIN). The schizophrenia dataset used for the analyses described in this study was obtained from the database of Genotype and Phenotype (dbGaP) found at http://www.ncbi.nlm.nih.gov/gap. We thank Dr. P.K. Gregersen for allowing us to use his RA dataset for this study.
