All locus annotations are based on the sentinel SNP (rs10494745) and 2 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
