The database of Genotypes and Phenotypes (dbGaP) is archiving the results of different Genome Wide Association Studies (GWAS). dbGaP has a multitude of phenotype variables, but they are not harmonized across studies.

We first extracted variables description, enriched them using domain knowledge, and computed the distances among them. We used clustering techniques to classify the ...[more]
