What's a GeneRIF?

A novel lacrimal gland autoantigen OBP1a is expressed in the thymus in an Aire-dependent fashion, suggesting that defective thymic expression of OBP1a may play a role in the spontaneous dacryoadenitis that develops in the Aire-deficient mouse model.
Title: An autoimmune response to odorant binding protein 1a is associated with dry eye in the Aire-deficient mouse.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
