DIDA is a novel database that provides for the first time detailed information on genes and associated genetic variants involved in digenic diseases,
the simplest form of oligogenic inheritance. Feel free to contact us at dida@ibsquare.be

DIDA – publication and citation
DIDA is published in the Nucleic Acids Research Database issue 2016 and has been selected as a NAR 2016 Breaktrough paper. The manuscript can be accessed here.

Predictors developed with DIDA

The data from DIDA was used in our research group to train machine learning predictors aiming to predict and understand the cause of digenic diseases: VarCoPP , which predicts the pathogenicity of digenic variant combinations and the Digenic Effect predictor, which differentiates between True Digenic, Monogenic plus modifier and Dual Molecular diagnosis cases. The latter was improved in a later work. These predictors can be cited as:
