Genome Wide Association Studies
From Computational Biology Group
Some people in our group work on genome wide association studies (GWAS).
Recommended reading
For an introduction to GWAS, with an emphasis on human studies, you could start with a nice tutorial article [1], and a review of more recent issues [2]. There is also a nice review about approaches for rodent studies [3].
Statistical Methodology
Software
Many statistical methods are implemented in PLINK.
More sophisticated model based genotype imputation and association testing can be performed using IMPUTE and SNPTEST, or using MACH and ProbABEL.
Our own software for association testing using uncertain genotypes is QUICKTEST.
