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_001099225.2 → NP_001092695.1  coiled-coil domain-containing protein 43 isoform 2

    Status: VALIDATED

    Description
    Transcript Variant: This variant (2) lacks an alternate exon in the 3' coding region, compared to variant 1, that causes a frameshift. The resulting protein (isoform 2) is shorter and has a distinct C-terminus, compared to isoform 1.
