    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.

    mRNA and Protein(s)

    1. NM_001286823.2NP_001273752.1  exonuclease mut-7 homolog isoform b

      Status: VALIDATED

      Description
      Transcript Variant: This variant (2) lacks several 3' exons but includes an alternate 3' exon, and it thus differs in the 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (b) has a distinct C-terminus and is significantly shorter than isoform a.

    1. NR_104598.2 RNA Sequence

      Status: VALIDATED

      Description
      Transcript Variant: This variant (3) includes three additional exons in the 5' region, and lacks several 3' exons but includes an alternate 3' exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).

      Status: VALIDATED

      Description
      Transcript Variant: This variant (4) shares two 5' exons but lacks the remaining exons found in variant 1, and it includes an alternate 3' exon, compared to variant 1. This variant is represented as non-coding because the predicted protein does not meet RefSeq quality criteria.
