You would need to read the RefSeq documentation (http://www.ncbi.nlm.nih.gov/RefSeq/), or try contacting the NCBI helpdesk, to find out more about the changes RefSeq typically makes to their accessions.
I can tell you how to find the revision history of any particular identifier, though: on the Nucleotide page at NCBI for a particular identifier, in the top-left corner of the page, select: Display Settings-> Revision history-> Apply. You will see a page like this one: http://www.ncbi.nlm.nih.gov/nuccore/NM_214677.1?report=girevhist which contains the entire history of changes made to the identifier. -- Brooke Rhead UCSC Genome Bioinformatics Group On 10/7/11 8:41 PM, Luqman Hakim Bin Abdul Hadi wrote: > Hi Brooke, > > Thanks for your reply - its helpful! > > Just to be sure, may I ask what usually follows when theres a change of id?
