Variable Somatic TIE2 Mutations in Half of Sporadic Venous Malformations

Abstract excerpt

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...
