ENA Study Registration Help
The IPD-IMGT/HLA Database now supports brokering of sequence submissions to the European Nucleotide Archive (ENA). This allows submitters to make a single submission to IPD-IMGT/HLA and have their sequences submitted to ENA on their behalf. In order to do this, submitters must first register an ENA study accession which can then be included in their submission to IPD-IMGT/HLA.
What is an ENA study accession number?
An ENA study accession number is a unique identifier for a study in the European Nucleotide Archive (ENA). All sequences submitted to ENA must be associated with a study. You can register a study using the ENA Study Registration Tool. Once you have registered your study you will be provided with a study accession number which can then be included in your submission to IPD-IMGT/HLA. A study can contain multiple sequences, so if you are submitting multiple sequences you can use the same study accession number for each sequence.
ENA Study registration fields
The ENA Study Registration Tool requires a small number of fields to be completed in order to register a study. These fields are described below:
| Field | Description | Example |
|---|---|---|
| Study Name | A unique name for the study. | ANRI_subs_July_2025 |
| Study Title | A short title given to the study. | HLA sequences from Anthony Nolan Research Institute in July 2025 |
| Study Description | A more detailed description of the study. | HLA sequences from the Anthony Nolan Research Institute in July 2025 |
