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.

Additional support for germline sets

We have created step-by-step walk-throughs showing how to use the AIRR-C germline sets with local installations of IgBLAST and MiXCR. These tools make use of download_germline_set, which is a powerful command-line utility which can be used to download sets in various formats, and explore the sets and versions available in OGRDB. It can even create… Continue reading Additional support for germline sets

Mouse IG Reference Sets Updated

Fixes have been made to two mouse reference sets. In C57BL/6 IGH, a stray character in the coding sequence for IGHV-KAOG has been removed. There are no other changes to this set. In PWD/PhJ IGH, the delineation j_cdr3_end has been corrected. There are no other changes in this set, and coding sequences are unchanged.

Human IG Reference Sets Updated

The human IG reference sets on OGRDB have been updated and carry new versions, but no coding sequences are affected. The updates add longer gene sequences for many light-chain alleles, allowing better characterisation of leader and RSS. Delineations of CDRs and other features have been reviewed and fixed in some cases. The changes made are… Continue reading Human IG Reference Sets Updated

OGRDB Updated

OGRDB has been updated to use binomial (latin) species names instead of colloquial names. The former names can still be used in calls to fetch germline sets, which I hope will prevent automated scripts from breaking, but if you do have problems please try substituting, for example, “Homo sapiens” for “Human”. This turned out to… Continue reading OGRDB Updated

Collaboration Opportunities

OGRDB and VDJbase are part of the AIRR Knowledge Commons project – bringing together immune repertoires from the AIRR Data Commons, epitopes from IEDB, receptor germline analysis from OGRDB and VDJbase with other emerging datasets. We are actively seeking collaborators whose projects will drive use cases and demonstrate the utility of bringing these various sources… Continue reading Collaboration Opportunities
