Two spondylarthritis phenotypes previously observed in different B27/Hubeta(2)m-transgenic lines also occurred in the respective CD8a(-/-)-transgenic rat lines. There was no difference in disease prevalence between CD8a(-/-) rats and CD8a(+/-) rats.

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.
