In TDR Targets, information about phenotypes that are caused by drugs, or by genetic manipulation of cells (e.g. gene knockouts or knockdowns) is manually curated from the literature. These descriptions help to describe the potential of the target for drug development. If no information is available for this gene or if the information is incomplete, this may mean that i) the papers containing this information either appeared after the curation effort for this organism was carried out or they were inadvertently missed by curators; or that ii) the curation effort for this organism has not yet started.

In any case, if you have information about papers containing relevant validation data for this target, please contact us.
