NCBIVariation Alfa Frequencies By Rsid
Get ALFA (Allele Frequency Aggregator) per-ancestry allele frequencies for a dbSNP rsID from NCBI Variation Services. Unlike dbSNP esummary global_mafs (one aggregate global frequency per study), this returns allele COUNTS and computed frequencies broken down by population/ancestry: European, African, African American, East Asian, Latin American, South Asian, Other Asian, etc. SAMN biosample IDs are resolved to ancestry names via the live ALFA frequency metadata, aggregating >1M dbGaP subjects.…
