08/06/2008: dbSNP FAQ Archive content update.
The online searchable dbSNP FAQ Archive has been updated with content from Winter, 2007/2008 and Spring, 2008.

06/18/2008: dbSNP Build 129 Rs Clustering Update and Docsum Schema Changes
Build 129, released on April 28, contained many instances where multiple human rs numbers mapped to the same location due to underclustering of new submitted SNPs (ss). This update fixes the underclustering problem (More...).

10/23/2007: RELEASE: NCBI dbSNP Build 128
The announcement is available here.

      * A follow-up announcement will be made to this mailing list (dbsnp-announce)
	when each component's actual release date is available. 

09/18/2007: dbSNP Site Map updated.
The dbSNP site map has been revised to update links and include new content.

03/18/2007: b127 XML UPDATE
Attention dbSNP user:

We discovered an error in our assignment of functional
class as it appears in the b127 XML files. The processing error 
affected approximately 380,000 SNPs. 

This error did NOT affect the b127 database tables. 

To correct this problem, the dbSNP re-created the XML files 
entirely on Friday, April 20, 2007.

If you have already processed the XML files before they were recreated, and would like to
fix the function class, one solution is to update the function
class by processing the database tables, 
b127_SNPContigLocusId_36_2.bcp.gz and SnpFunctionCode.bcp.gz
that contain the correct function class codes. 

These tables are on the ftp site:

If you have specific questions regarding this error please 
contact us at

We apologize for the inconvenience that this error may have

Best regards,

dbSNP Staff.
