In principle, you cannot remove your sequence data from DDBJ retrieval system: getentry, if it has already been open to the public (If DDBJ wrongly published your data because of any mistakes, the data should be removed as soon as possible.).
However, if there is some specific reason for removing your sequence data (i.e. some error is found, etc.), we can restrict access to your sequence data.

Moreover, our unified database may be copied and redistributed without permission at any other organizations. In case you need to withdraw your entry from such database, we ask you to make request directly to the organization which manages the database.
