NCBI Reference Sequences (RefSeq)

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 (2) lacks three alternate exons, resulting in the loss of an in-frame segment in the 5' coding region, compared to variant 1. The encoded isoform (b) is shorter than isoform a.

RNA

  1. NR_104480.2 RNA Sequence

    Status: VALIDATED

    Description
    Transcript Variant: This variant (4) lacks two alternate internal exons, 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 (5) lacks four internal exons, compared to variant 1. This variant is represented as non-coding because the predicted protein does not meet RefSeq quality criteria.
