    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.

    1. NR_024605.3 RNA Sequence

      Status: VALIDATED

      Description
      Transcript Variant: This variant (3) lacks an alternate exon in the 5' region, uses an alternate splice site in the central region and includes an additional splice junction in the 3' region, compared to variant 1. This variant is represented as non-coding because the use of the supported translational start codon, as in variant 1, would result in nonsense-mediated mRNA decay (NMD).
