Our new post-GWAS analysis method (network density analysis; NDA) reveals new biological features of numerous disease states and traits. It works by examining a coexpression network of transcription start sites (discovered in FANTOM5). We find that transcripts containing GWAS hits for a given trait tend to fall into more dense groupings in the coexpression network than randomly-selected transcripts.Baillie JK et al.

Upload a list of SNPs (or genomic locations) in the format described below. The SNPs should share some common feature, such as putative association with a given phenotype at a permissive p-value threshold (eg. 5e-6), such that it might reasonably be expected that some of the SNPs in the entry set will share an expression profile across the FANTOM5 expression atlas.

If you submit a correctly-formatted file using the form above, your job will be entered into our queue for running on the Roslin Institute servers. Very large jobs (those with more than 1000 SNPs, or more than 400 SNPs mapping to FANTOM5 TSS) may take a long time and these will be pushed down the queue during busy periods, and may be cancelled if they are taking too long. Please contact us () if you have a very large job, or download our code below and run it on your own server.
