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.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

  1. NM_032762.2: Suppressed sequence

    NM_032762.2: This RefSeq was permanently suppressed because it is now thought that this gene does encode a protein.
