There are two types of pQTLs:
- Cis-pQTLs are variants that are proximal to the gene encoding the protein under study. Cis-pQTLs are strong instruments for determining if a protein biomarker for disease is causing disease or elevated or suppressed as a consequence of it.
- Trans-pQTLs are involved in the distal regulation of proteins via an often unknown path. Trans-pQTLs can provide unique insights into molecular connections in human biology.
