We have opened direct access to the gene2pheno database, where we are hosting the PrediXcan results of close to 3000 phenotypes (from public GWAS meta analysis results and UKBiobank results from Ben Neale/HAIL team).

Below are R functions that will allow you access and query the database. These results are based on GTEx V6p models and details of the analysis can be found in our preprint link to preprint in press now in Nature Communications.

Usual disclaimers apply. This is provided for your convenience and with the hope of being useful. We provide no guarantee of accuracy etc…

Via PostgreSQL

The code below may not be completely self explanatory. We are working on the documentation.

## First run the preliminary command further down

## this will fetch all associations for Schizophrenia
data = query.pheno("pgc_scz")

## this will fetch all associations for FTO
data = query.gene("FTO")

## these rather small tables will be handy

phenotb = dbGetQuery(db,"select * from pheno")
tissuetb = dbGetQuery(db,"select * from tissue")
genetb = dbGetQuery(db,"select * from gene")
phenoinfo = phenotb %>% inner_join(dbGetQuery(db, "select * from pheno_info"),by=c("id"="pheno_id") )

You will need to run the following preliminary commands first


## Connect to DB
drv <- dbDriver("PostgreSQL")

db  <-   dbConnect(drv, host="gene2pheno.ccsriudvs1y0.us-east-1.rds.amazonaws.com", port="5432", dbname="release_2017_09_14", user="metaxcan_ro", password="M3t4Xc4nR0")

db.uk <- dbConnect(drv, host="gene2pheno.ccsriudvs1y0.us-east-1.rds.amazonaws.com", port="5432",
dbname="ukb_neale_2017_10_14", user="metaxcan_ro", password="M3t4Xc4nR0")

## Currently, gene2pheno.org is serving results based on GTEx V6p. Expanded list of phenotypes can be retrieved using this dbname=“public_gwas_v6p_hapmap_2017_12_04”

Via BigQuery

If you have a Google Cloud Platform account (you can get a free account with a small credit included in Google Cloud) you can query directly from the webpages

Via gene2pheno.org

Of course you can also query using our app link
