ADGRG6
ADGRG6: A Comprehensive Guide to the Gene and Its Implications
Description
ADGRG6 is a gene that encodes a member of the adhesion G protein-coupled receptor (GPCR) family. These receptors are characterized by the presence of an extracellular adhesion domain and a seven-transmembrane domain. The ADGRG6 protein is specifically expressed on the surface of platelets, megakaryocytes, and certain immune cells.
Function
ADGRG6 plays a crucial role in platelet activation and thrombosis. It binds to its ligand, laminin-411, which is present on the surface of damaged blood vessels. This binding triggers a cascade of signaling events that lead to platelet activation, aggregation, and the formation of a blood clot.
Associated Diseases
Mutations in the ADGRG6 gene have been linked to several bleeding disorders, including:
- Glanzmann thrombasthenia: A rare inherited disorder characterized by a deficiency of functional platelets.
- Scott syndrome: A rare inherited disorder characterized by a prolonged bleeding time.
- Platelet function defects: ADGRG6 mutations can cause impaired platelet function, leading to an increased risk of bleeding.
Did you Know ?
Approximately 1 in 10,000 individuals worldwide is affected by Glanzmann thrombasthenia, which is caused by mutations in the ADGRG6 gene.
