Attention dbSNP user:
We discovered two problems with SNP annotation on RefSeq mRNA.
Problem 1: A drop in the total number of SNP
annotations from dbSNP build 129 onto human mRNA sequences for RefSeq
releases 28, 29, and 30.
Problem 2: dbSNP has also identified a separate problem of redundant
SNP annotations on RefSeq mRNAs where the same rs number is annotated
more than once on the same mRNA.
If you have specific questions regarding these problems please
contact us at firstname.lastname@example.org.
We apologize for the inconvenience that these errors may have
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
