Klippel-Trenaunay-Weber syndrome

A congenital disease (OMIM:149000) characterised by malformations of capillary (98% of patients), venous (72%) and lymphatic (11%) vessels, as well as bony and soft tissue hypertrophy, leading to large cutaneous haemangiomas with hypertrophy of the related bones and soft tissues.

Molecular pathology
Defects in AGGF1 on 5q13.3, which encodes a protein that promotes angiogenesis and endothelial cell proliferation, are a cause Klippel-Trenaunay syndrome. Other potential Klippel-Trenaunay-Weber syndrome gene loci have been identified at 8q22.3 and 14q13.

Klippel-Trenaunay syndrome is a rare non-hereditary congenital abnormality characterized by a clinical triad of soft tissue hypertrophy of extremity, varicosities and cutaneous hemangiomas or lymphongioma.
Genitourinary hemangiomas have been described in Klippel-Trenaunay syndrome (cutaneous port-wine hemangiomas, varicose veins, and ipsilateral soft tissue and bony hypertrophy of the involved extremities).
Less common causes of varicosities of the leg veins include arterio-venous malformations and congenital anomalies, such as the Klippel-Trenaunay syndrome. The perforating veins contain valves which normally only permit flow from the superficial to the deep system.
Jessica Shakeshaft, who suffers from Klippel-Trenaunay syndrome, has already undergone 32 operations to tackle the rare circulatory disorder which can cause disfigurement of limbs.
Stephen was born with Klippel-Trenaunay syndrome, which affects about 1500 people worldwide.
