    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) differs in the 5' UTR and represents the use of an alternate promoter, compared to variant 1, which results in the use of an in-frame downstream start codon and a protein (isoform 3) with a shorter N-terminus, compared to isoform 1.

    1. NR_051978.2 RNA Sequence

      Status: VALIDATED

      Description
      Transcript Variant: This variant (4) lacks an alternate exon in the 5' coding region, compared to variant 1, which results in a frameshift and early stop codon. The transcript is sufficiently abundant to represent as a RefSeq; however, the predicted protein is not represented because the product is significantly truncated and the transcript is a candidate for nonsense-mediated mRNA decay (NMD).
