NHGRI grant recipients continuing SNP work include genome centers, private, extra-mural research labs, and private businesses.

HapMap contains SNPs found in dbSNP only (refSNP numbers). Exceptions to the above mentioned synchronizations may occur in between builds. Any SNP that is identified by a refSNP(rs) number originated in dbSNP, as dbSNP assigns rs numbers.
