Integrating genetic and gene expression evidence into genome-wide association analysis of gene sets

DOI: 
10.1101/gr.124370.111

Single variant or single gene analyses generally account for only a small proportion of the phenotypic variation in complex traits. Alternatively, gene set or pathway association analyses are playing an increasingly important role in uncovering genetic architectures of complex traits through the identification of systematic genetic interactions. Two dominant paradigms for gene set analyses are association analyses based on SNP genotypes and those based on gene expression profiles.

Genomic contributions to Mendelian disease

DOI: 
10.1101/gr.123554.111

Genomic research has two quite distinct faces. On the one hand, it produces large, curated, reference data sets through numerous networks of investigators for community use—although this aspect has great and widespread utility, it does not inspire per se. On the other hand, it allows an unbiased genome-wide view that is exciting precisely because it habitually uncovers biology that we were hopelessly ignorant about.

Singapore Genome Variation Project: A haplotype map of three Southeast Asian populations

DOI: 
10.1101/gr.095000.109

The Singapore Genome Variation Project (SGVP) provides a publicly available resource of 1.6 million single nucleotide polymorphisms (SNPs) genotyped in 268 individuals from the Chinese, Malay, and Indian population groups in Southeast Asia. This online database catalogs information and summaries on genotype and phased haplotype data, including allele frequencies, assessment of linkage disequilibrium (LD), and recombination rates in a format similar to the International HapMap Project.

JBrowse: A next-generation genome browser

We describe an open source, portable, JavaScript-based genome browser, JBrowse, that can be used to navigate genome annotations over the web. JBrowse helps preserve the user's sense of location by avoiding discontinuous transitions, instead offering smoothly animated panning, zooming, navigation, and track selection.

High-resolution mapping and analysis of copy number variations in the human genome: A data resource for clinical and research applications

We present a database of copy number variations (CNVs) detected in 2026 disease-free individuals, using high-density, SNP-based oligonucleotide microarrays. This large cohort, comprised mainly of Caucasians (65.2%) and African-Americans (34.2%), was analyzed for CNVs in a single study using a uniform array platform and computational process. We have catalogued and characterized 54,462 individual CNVs, 77.8% of which were identified in multiple unrelated individuals.

The ClinSeq Project: Piloting large-scale genome sequencing for research in genomic medicine

ClinSeq is a pilot project to investigate the use of whole-genome sequencing as a tool for clinical research. By piloting the acquisition of large amounts of DNA sequence data from individual human subjects, we are fostering the development of hypothesis-generating approaches for performing research in genomic medicine, including the exploration of issues related to the genetic architecture of disease, implementation of genomic technology, informed consent, disclosure of genetic information, and archiving, analyzing, and displaying sequence data.

DNA Sudoku--harnessing high-throughput sequencing for multiplexed specimen analysis

An interesting new approach to large-scale sequencing pooled DNA. Here's the abstract, but see also the the links for a brief news item from Nature Reviews Genetics.
