Virtual Issue: Design and Analytic Approaches in Sequencing Studies (free online)

Editor: Sanjay Shete

In the post-GWAS era, investigators have shifted their focus on identifying rare causal variants through sequencing. Although the cost of whole genome sequencing has dropped significantly, it is still expensive to perform the whole genome sequencing for thousands of individuals at a high coverage depth. The papers selected in this virtual issue discuss topics such as: optimal number of unrelated individuals or family members to select for sequencing; two-stage designs; imputation to infer sequences; advantage and cost-efficiency of extreme phenotype sampling in rare-variant analyses; using linkage information to select pedigree members for sequencing; an approach for assigning weights based on sibpairs and observed odds ratios to identify rare and common variants; a Bayesian approach to identify rare variants within a gene; and an approach to use data from different sources to increase efficiency in making genotype calls for rare SNPs. All these articles are freely available online.
