Klippel-Trenaunay-Weber syndromeA 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.
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.
