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 (3) uses an alternate splice junction at the 5' end of an exon, that causes a frameshift. It also lacks the next exon, which restores the correct reading frame. The resulting isoform (3) has a shorter, alternate internal segment compared to isoform 1.
