    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.

      Description
      Transcript Variant: This variant (2) lacks an in-frame exon in the mid-coding region compared to variant 1. The resulting shorter isoform (2) has the same N- and C- termini but lacks an internal protein segment compared to isoform 1.

    RNA

    1. NR_136622.2 RNA Sequence

      Status: VALIDATED

      Description
      Transcript Variant: This variant (3) uses an alternate acceptor splice site at an internal exon compared to variant 1. It is represented as non-coding because the use of the 5'-most translational start codon, as used in variant 1, renders this transcript a candidate for nonsense-mediated mRNA decay (NMD).
