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 initial release of ~100 thousand subjects included allele counts and frequency for 447 million rs site including 4 million novel ones aggregated from 551 billion genotypes. 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>.
