We don’t know the causes of hemangiomas themselves. We are doing studies to look at genetic links between other syndromes like Klippel Trenaunay Syndrome and other syndromes involved in birthmarks. However, at this current time we do not know what really predisposes patients that having those. You do have a larger number or percentage of patients with parents who had fetal alcohol syndrome or premature birth. Otherwise, we don’t have any other predisposing factors that we definitively know cause hemangiomas.
