COURSE SUMMARY

Novel statistical methodology can enhance understanding of the interactions between multiple genes and environmental factors on a complex disease. The massive amount of high-throughput genomic data brings a great challenge of developing advanced statistical and computational data mining tools. In this course, we will go through some effective statistical methods for analyzing these high-throughput data. The course especially focuses on two types of high-throughput data: gene expression microarray and single nucleotide polymorphism (SNP) markers.

Topics include

Ÿ Gene expression:

- Technology and measurement

- Quality assessment

- Preprocessing Affymetrix GeneChip: background adjustment, normalization and summarization

- Differential expression

- Clustering and prediction

- Gene set enrichment analysis

Ÿ SNP markers:

- Preliminary analyses: Hardy-Weinberg equilibrium, haplotype and genotype data, measures of linkage disequilibrium, estimates of recombination rates, SNP tagging

- Population-based association study: case-control and family study

- Candidate-gene and genome-wide association studies

- Population stratification

- Tests of association: single and multiple SNPs

- Epistatic effects and gene-environment interactions

- Multiple testing
