  • Binds heme and transports it to the liver for breakdown and iron recovery, after which the free hemopexin returns to the circulation.
  • Scavenging of heme from plasma

All locus annotations are based on the sentinel SNP (rs10801582) and 17 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.
