Zimmerman-Laband syndrome is a genetically inherited congenital disorder, which is also referred to as Laband's Syndrome.
Affected infants have gingival fibromatosis, nail dysplasia, joint hypermobility, and sometimes hepatosplenomegaly. They have abnormal facial features due to an unusually large and poorly developed nose and pinnae. They may also develop mental retardation.
A parent who had the abnormal gene may pass on the disorder to his or her offspring.
