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.

RNA

  1. NR_178045.1 RNA Sequence

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2, non-coding) uses the same exon combination as variant (2, coding) but represents the allele present on the T2T-CHM13v2.0 genome assembly. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
