What's a GeneRIF?

Kv8.2 knock-out (KO) mice show many similarities to human cone dystrophy with a supernormal rod response, including a depressed a-wave and an elevated b-wave response with bright light stimulation. Optical coherence tomography imaging and immunohistochemistry indicate that the changes in six-month-old Kv8.2 KO retinae are largely limited to the outer nuclear layer, while outer segments appear intact.

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.
