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. NG_026640.1: Suppressed sequence

    Description
    NG_026640.1: This RefSeq was permanently suppressed because it is now thought that this pseudogene is transcribed.

  2. NM_001008748.2: Suppressed sequence

    Description
    NM_001008748.2: This RefSeq was suppressed temporarily because the source transcript appears to be partial (the encoded protein is not consistent with other maltases) and an alternate source was not identified.

  3. NR_003715.1: Suppressed sequence

    Description
    NR_003715.1: This RefSeq was permanently suppressed because it is now thought that this gene does encode a protein.

  4. NR_003717.1: Suppressed sequence

    Description
    NR_003717.1: This RefSeq was temporarily suppressed because currently there is not sufficient data to support this transcript.
