Description
+The NCBI ALlele Frequency Aggregator (ALFA) + pipeline is developed to compute allele frequency for variants in dbGaP + across approved un-restricted studies and to provide the data as +open-access to the public through dbSNP. The goal of the ALFA project is + to make frequency data from over 1M dbGaP subjects open-access in +future releases to facilitate discoveries and interpretations of common +and rare variants with biological impacts or causing diseases.
+The R4 release of 408,709 subjects included allele +counts and frequency for 15.5 million rs site including 959,966 ClinVar RS IDs. More information about ALFA can +be found at https://www.ncbi.nlm.nih.gov/snp/docs/gsr/alfa/ and any +questions about ALFA track data should be forwarded to +<mailto:snp-admin@ncbi.nlm.nih.gov>.
+Subtracks
+This track contains data from 12 populations:
