Hereditary hemorrhagic capillary dilatation is a disorder of abnormal development and dilation of blood vessels due to a genetic mutation, which is not contagious and is prevalent mainly in young and middle-aged people. Hereditary hemorrhagic capillary dilatation is caused by mutations in endothelial glycoprotein or ACVRL1, which has been reported in the literature to be associated with transforming growth factor beta superfamily signaling. The hereditary hemorrhagic capillary dilatation gene is primarily associated with the vascular endothelium, and mutations in it can further lead to structural abnormalities of the vasculature, ranging from microvessels to large arteries and veins several centimeters in diameter. Abnormalities in the vascular structure make the walls of the blood vessels become more prone to rupture and there is turbulence of blood that develops.
