What's a GeneRIF?

Our study identified five new loci associated with VKH susceptibility and identified a functional variant (lnc-TOR3A-1:1/rs3829794) that confers risk for VKH, which is possibly mediated by modulating gene expression, proliferation of lymphocytes, and regulation of anti-inflammatory cytokine production.

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.
