Welcome to OGRDB - the curated Open Germline Receptor Database!

The immune receptors of B and T cells are central to the body's response to pathogens, and implicated in autoimmune disease. High-throughput sequencing of receptor repertoires - AIRR-Seq - is widely used to study receptor development, however a comprehensive understanding of the genes from which development starts - the germline genes - is crucial for accurate interpretation. Our knowledge of human receptor alleles is incomplete, and that of other species at an early stage. OGRDB is an open database of newly discovered alleles, through which researchers can contribute newly discovered alleles for analysis, and download those that have been reviewed and affirmed.

Germline sets now have DOIs

Germline sets on OGRDB are copied to Zenodo.org for long-term security and have DOIs issued by Zenodo which you will see on the Germline Sets pages. The DOI is updated with each version: you can provide the DOI for the version used in your research as a permanent link to the set.

Using the OGRDB mouse germline sets

For many analyses, it is important to annotate AIRR-seq repertoires with an accurate and comprehensive germline set. As an example, determination of the overall mutation rate of a repertoire may give misleading results if frequently-expressed sequences are omitted. Likewise, many methods of clonal assignment require an accurate determination of the germline. The IG loci of… Continue reading Using the OGRDB mouse germline sets

Tools for working with germline sets

The AIRR-C standard germline sets published in OGRDB use a new naming scheme: please see this poster for details. Because the format of these names may not be compatible with all current pipeline tools, we have released receptor-germline-tools: utilities that can convert to more compatible subgroup-identifier-allele form. If you have issues using the germline sets… Continue reading Tools for working with germline sets

First Germline Sets Published on OGRDB

We have published IGHV germline sets for laboratory mouse strains BALB/c and C75BL/6, as recently reported in preprint by Jackson et al.The sets will be curated by the AIRR Community Germline Database Working Group with the aim of maintaining sets that are tuned for use in AIRR-seq, taking advantage of the latest research. We hope… Continue reading First Germline Sets Published on OGRDB

New inferred sequences accepted by IMGT

A new batch of inferred receptor sequences, submitted for review through OGRDB, has been accepted by IMGT and should be added to their reference sets shortly. This batch included the first IGK and IGL alleles. We have now affirmed a total of 32 sequences, details of which can be found on the Sequences page.
