Research Abstract

This study aimed to identify and characterize the disease-related genes involved in Rho family small GTPase signaling pathways to understand the pathogenesis of cardiovascular diseases and mental disorders. We found that the SNP (Ala370Ser) within PH domain of ARHGAP9, which is a negative regulator of Rac, was associated with a significant risk of coronary artery spasm. The Ala370Ser polymorphism counteracted ARHGAP9-reduced cell migration, spreading and adhesion, suggesting that it results in a critical difference in ARHGAP9 function.
