    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 (4) differs in the 5' UTR, lacks a portion of the 5' coding region and initiates translation from a downstream AUG compared to variant 1. This variant also lacks an exon in the 3' coding region which results in a frameshift compared to variant 1. The encoded isoform (4) has a shorter N-terminus and a distinct C-terminus compared to isoform 1.
