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.

    Status: VALIDATED

    Description
    Transcript Variant: This variant (3) contains an alternate exon in the 3' coding region, which results in a frameshift, compared to variant 1. The encoded isoform (3) is longer and has a distinct C-terminus, compared to isoform 1.
