    What's a GeneRIF?
    1. PSMG4 and NLRP5 appear of particular interest as they were found to be associated with more than one clinical phenotype and are implicated in biological processes considered relevant to the pathophysiology of MS. Also, PSMG4 p.W99R and NLRP5 p.R761L were found to correlate with an earlier age of MS clinical onset. Our data suggests PSMG4 and NLPR5 as potential targets for the development of modifying therapies for MS.

    2. a crystal structure of human PAC4 at 1.90-A resolution. Crystallographic data identify a hydrophobic surface that is surrounded by charged residues. The hydrophobic surface is complementary to that of its binding partner, PAC3.

    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.
