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 R5 release of 436,921 subjects included allele counts and frequency for 908 million rs site including 2 million novel ones aggregated from thousand billions of 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>.
