Table 3 GTEx and RegulomeDB data on SNPs under positive selection in European populations (GBR, TSI, FIN). Given is also a summary of reported traits from the NHGRI-EBI GWAS catalogue. GTEx eQTLs–eGene interaction with p < 0.0001. RegulomeDB rank: 2b: TF binding + any motif + DNase Footprint + DNase peak; 3a: TF binding + any motif + DNase peak; 4–5: TF binding + DNase peak; 6: motif hit. The RegulomeDB probability score ranges from 0 to 1, with 1 being most likely to be a regulatory variant (for further details see54). Transcription factor HNF4A, an important regulatory element of the ALDH2 gene expression, is given in bold.

From: Positive selection acts on regulatory genetic variants in populations of European ancestry that affect ALDH2 gene expression
