dbSNP

dbSNP contains human single nucleotide variations, microsatellites, and small-scale insertions and deletions along with publication, population frequency, molecular consequence, and genomic and RefSeq mapping information for both common variations and clinical mutations.

ALFA Project Release 2 with over 900M variants from 192K subjects is now available (January 6, 2021)


The goal is to provide allele frequency from more than 1 million dbGaP subjects with regular updates. Visit the project page for more information or view the introduction video below. Please provide your feedback by completing this short 3 min survey.
