Database of Genotypes and Phenotypes (dbGaP)
Description
The database of Genotypes and Phenotypes (dbGaP) is a database initiated by the National
Library of Medicine (NLM), part of the National Institutes of Health (NIH). It is part of
the NCBI and was developed to archive and distribute the results of studies that have
investigated the interaction of genotype and phenotype. Such studies include genome-wide
association studies, medical sequencing, molecular diagnostic assays, as well as
association between genotype and non-clinical traits. The advent of high-throughput,
cost-effective methods for genotyping and sequencing has provided powerful tools that
allow for the generation of the massive amount of genotypic data required to make these
analyses possible.
dbGaP provides two levels of access -- open and controlled -- in order to allow broad
release of non sensitive data, while providing oversight and investigator accountability
for sensitive data sets involving personal health information. Summaries of studies and
the contents of measured variables as well as original study document text are generally
available to the public, while access to individual-level data including phenotypic data
tables and genotypes require varying levels of authorization.
