Venous malformations (VMs) are the most frequent vascular malformations referred to specialized vascular anomaly centers. A rare (1-2%) familial form, termed cutaneomucosal venous malformation (VMCM), is caused by gain-of-function mutations in TIE2. More recently, sporadic VMs, characterized by the presence of large unifocal lesions, were shown to be caused by somatic mutations in TIE2. These include a frequent L914F change, and a series of double mutations in cis. All of which cause ligand… CONTINUE READING
