Updating and deleting allele sequence definitions


You cannot update the sequence of an allele definition. This is for reasons of data integrity since an allele may form part of a scheme profile and be referred to in multiple databases. If you really need to change a sequence, you will have to remove the allele definition and then re-add it. If the allele is a member of a scheme profile, you will also have to remove that profile first, then re-create it after deleting and re-adding the allele.

In order to update or delete an allele, first you must select it. Click the update/delete sequences link.


Either search for specific attributes in the search form, or leave it blank and click ‘Submit’ to return all alleles. For a specific allele, select the locus in the filter (click the small arrow next to ‘Filter query by’ to expand the filter) and enter the allele number in the allele_id field.


Click the appropriate link to either update the allele attributes or to delete it. If you have appropriate permissions, there may also be a link to ‘Delete ALL’. This allows you to quickly delete all alleles returned from a search.


If you choose to delete, you will be presented with a final confirmation screen. To go ahead, click ‘Delete’. Deletion will not be possible if the allele is part of a scheme profile - if it is you will need to delete any profiles that it is a member of first. You can also choose to delete and retire the allele identifier. If you do this, the allele identifier will not be re-used. It is possible to set the configuration so that you only have the option to delete and retire.


If instead you clicked ‘Update’, you will be able to modify attributes of the sequence, or link PubMed, ENA or Genbank records to it. You will not be able to modify the sequence itself.


Adding flags and comments to an allele record requires that this feature is enabled in the database configuration.
