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.

    Description
    Transcript Variant: This variant (1) differs in the 5' UTR and has multiple coding region differences compared to variant 3. These differences cause translation initiation at a downstream AUG and result in an isoform (1) with a shorter N-terminus compared to isoform 3. Variants 1, 2, and 7 all encode the same isoform (1).
