GeneRIFs: Gene References Into Functions

What's a GeneRIF?

C9orf82ko/ko mice were born at a Mendelian ratio and did not display any overt macroscopic or histological abnormalities. DNA double-strand breaks repair dependent processes like lymphocyte development and class switch recombination (CSR) appeared normal, arguing against a link between the C9orf82 encoded protein and V(D)J recombination or CSR.

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.
