UniProt Comment
  • Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. Involved in the down-regulation of the immune response and the development of tolerance. Competes with CD8A for binding to class I MHC antigens. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.
Reactome
  • Immunoregulatory interactions between a Lymphoid and a non-Lymphoid cell

All locus annotations are based on the sentinel SNP (rs103294) and 24 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.

Prostate cancer related.

This is a replicated cis-pQTL to Leukocyte immunoglobulin-like receptor subfamily B member 2 (LILRB2). It is a risk-locus for prostate cancer [PubMed]. SNP rs103294 is in strong linkage equilibrium with a 6.7-kb germline deletion that removes the first six of seven exons in LILRA3 – reported in Chinese. Imputing yields much stronger associations, i.e. with coding variant rs386056.

The information gathered here is a result of an attempt to keep track of all interesting information that we encountered while investigating these loci. Please bear in mind that the annotation given here is neither complete nor free of errors, and that all information provided here should be confirmed by additional literature research before being used as a basis for firm conclusions or further experiments.
