    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) has multiple differences compared to variant 1. These differences result in a distinct 5' UTR, translation initiation at a downstream start codon and lack of an internal in-frame segment, compared to variant 1. The encoded protein (isoform c) is shorter than isoform a.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (2) uses an alternate in-frame splice site in the internal coding region compared to variant 1. This results in a shorter protein (isoform b) compared to isoform a.
