Target (full name) ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 2
Somalogic ID (Sequence ID) SL008644 (4535-50_2)
Entrez Gene Symbol BST1
UniProt ID Q10588
UniProt Comment
  • Synthesizes the second messagers cyclic ADP-ribose and nicotinate-adenine dinucleotide phosphate, the former a second messenger that elicits calcium release from intracellular stores. May be involved in pre-B-cell growth.

All locus annotations are based on the sentinel SNP (rs2302465) and 77 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.

Near total protein loss of BST1 in homozygotes of certain minor allele variants.

Multiple replicated cis-pQTLs to ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase 2 (BST1). BST1 is an extracellularly exposed enzyme that possesses Cyclic ADP ribose (cADPR) hydrolase activity. cAD is a second messenger that releases calcium from intracellular calcium stores. BST1 is mainly expressed in the bone marrow. It appears that the minor allele variants of both, rs2302465 (Locus 18) and rs7657257 (Locus 151), tag haplotypes that carry the same functional variant, and which leads to full loss of BST1. Using imputed data a number of highly significant SNPs were identified, i.e. SNP rs73224659 (p=4.0×10-179 compared to p=1.5×10-108 for rs2302465). Minor allele carriers of rs73224659 show nearly no protein levels of BST1.
