==Causes== This feature can occur on its own with no underlying health problems, or it can be associated with certain medical conditions, including Marfan syndrome, Ehlers–Danlos syndromes, Loeys–Dietz syndrome, and homocystinuria. It is also seen in congenital contractural arachnodactyly, which is caused by mutation in the gene encoding fibrillin-2 on chromosome 5q23.
