Interpreting Sequence Details
More Help

This help document describes how to interpret the following fields on a sequence detail report.

FIELD DESCRIPTION
ID/VersionThe primary and secondary (if they exist) sequence identifiers appear on the left. The ID is primary if it appears in boldface type; if the type face is not bold, it is a secondary ID. The name of the sequence provider appears beside the ID in parentheses, linked to the sequence detail report at the provider's web site. On the right is the provider's version number for the sequence. Sometimes this takes the form of the latest sequence or annotation update. If version information is missing, the provider did not supply it. If the sequence is associated with one of the genome assemblies, a link to the Multiple Genome Viewer (MGV) will be present and will allow you to view that genome features's sequence in all the assembled genomes.
Sequence
description
from provider		Typically, this is the information contained in the Definition or Description field of the provider's sequence record. If this field is blank, the provider did not supply the information. For genome assembly sequences, the coordinates, the chromosome, and the build number appear. The build number is from the most current NCBI assembly sequence.
ProviderName of the sequence provider and sometimes the division (e.g., Rodent, High Throughput cDNA, High Throughput Genome, Patent, MGP, EST, STS, GSS) of origin. This sequence has been deleted from the provider database appears if the provider no longer has the sequence.
SequenceType and length of the sequence; amount of flanking sequence.
TypeDNA, RNA, or polypeptide.
LengthFor RNA and DNA sequences length is in base pairs (bp); for polypeptides, length is in amino acids (aa).

You can:

  • download this sequence in FASTA format or forward it to NCBI BLAST

Click the arrow to select/deselect and GO to activate. (If the sequence is marked as deleted, this option is not available.) The default is to download the file in FASTA format; a FASTA sequence file containing the selected sequence appears in your browser window. When you forward a sequence to NCBI BLAST, it will appear on a NCBI BLAST submission form.

SourceAll available sequence source attribute data (i.e., library, organism, strain/species, sex, age, tissue, cell line). For some sequence providers (e.g., UniProt, NIA) a link is available. If an asterisk follows a data item, it means that we could not map information from the provider to an item in our database. (Providers describe sequence attributes — strains/species, tissues, libraries, clone collections, and so on — in their reports. MGI captures these original values, converts them to MGI controlled vocabularies if possible, and stores them.
Chromosome Chromosomal assignment of markers associated to the sequence.
  • If a set of markers maps to multiple chromosomes (as, for example, with a chimeric YAC), each chromosome is listed.
  • If multiple markers are associated to the sequence and at least one is mapped, the identified chromosome appears.
  • If one or more markers are associated to the sequence but none are mapped, Unmapped appears.
  • If there are no markers associated to the sequence, this field is blank.
Annotated
genes and
markers		Type, Symbol (linked to the MGI Marker Detail report), Name, and the number of GO Terms, Expression Assays, Orthologs and Phenotypic Alleles annotated to the markers that the sequence is associated with.
MGI curated
clones/probes
annotated to sequence		For any probe/clone associated to the sequence, the following appear: Name (linked to its Molecular Probes and Clones detail report), Clone Collection, Clone ID, and Type (cDNA, DNA construct, genomic, mitochondrial, oligo, primer, Not specified). If the clone belongs to multiple clone collections, each appears on a separate line.
Sequence
references
in MGI		If a reference with an MGI number refers to a record from any of our sequence providers (GenBank/EMBL/DDBJ, RefSeq, UniProt, NIA Mouse Gene Index), the report displays all references in MGI associated with the sequence.
