    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 5' terminal exon compared to variant 1. This variant is represented as non-coding because the predicted protein does not meet RefSeq quality criteria.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (5) contains an alternate 3' exon structure compared to variant 2. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 2, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
