Accession number (bioinformatics)
An accession number in bioinformatics is a unique identifier given to a DNA or protein sequence record to allow for tracking of different versions of that sequence record and the associated sequence over time in a single data repository. Because of its relative stability, accession numbers can be utilized as foreign keys for referring to a sequence object, but not necessarily to a unique sequence. All sequence information repositories implement the concept of "accession number" but might do so with subtle variations.LRG
Locus Reference Genomic records have unique accession numbers starting with LRG_ followed by a number. They are recommended in the as stable genomic reference sequences to report sequence variants in LSDBs and the literature.
