Description

The NCBI RefSeq Genes composite track shows 31 Dec 2019 Aythya fuligula/GCF_009819795.1_bAytFul2.pri protein-coding and non-protein-coding genes taken from the NCBI RNA reference sequences collection (RefSeq). All subtracks use coordinates provided by RefSeq. See the Methods section for more details about how the different tracks were created.

Please visit NCBI's Feedback for Gene and Reference Sequences (RefSeq) page to make suggestions, submit additions and corrections, or ask for help concerning RefSeq records.

For more information on the different gene tracks, see our Genes FAQ.

Display Conventions and Configuration

To show only a selected set of subtracks, uncheck the boxes next to the tracks that you wish to hide.

The tracks available here can include (not all may be present):
RefSeq annotations and alignments

The RefSeq All, RefSeq Curated and RefSeq Predicted, tracks follow the display conventions for gene prediction tracks. The color shading indicates the level of review the RefSeq record has undergone: predicted (light), provisional (medium), or reviewed (dark), as defined by RefSeq.

Color Level of review
Reviewed: the RefSeq record has been reviewed by NCBI staff or by a collaborator. The NCBI review process includes assessing available sequence data and the literature. Some RefSeq records may incorporate expanded sequence and annotation information.
Provisional: the RefSeq record has not yet been subject to individual review. The initial sequence-to-gene association has been established by outside collaborators or NCBI staff.
Predicted: the RefSeq record has not yet been subject to individual review, and some aspect of the RefSeq record is predicted.

The RefSeq Alignments track follows the display conventions for PSL tracks.

The item labels and codon display properties for features within this track can be configured through the controls at the top of the track description page. To adjust the settings for an individual subtrack, click the wrench icon next to the track name in the subtrack list.

Methods

The RefSeq annotation and RefSeq RNA alignment tracks were created at UCSC using data from the NCBI RefSeq project. GFF format data files were downloaded from the file GCF_009819795.1_bAytFul2.pri_genomic.gff.gz delivered with the NCBI RefSeq genome assemblies at the FTP location:
ftp://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/009/819/795/GCF_009819795.1_bAytFul2.pri/ The GFF file was converted to the genePred and PSL table formats for display in the Genome Browser. Information about the NCBI annotation pipeline can be found here.
