Cutis Laxa

Cutis Laxa is a heritable disorder of connective tissue characterized by redundant, inelastic, and wrinkled skin. Other organ systems may be variably involved and the spectrum of clinical severity ranges from relatively mild to lethal in early childhood. Additional features may include joint hypermobility, pulmonary emphysema, cardiovascular abnormalities, hernias and gastrointestinal diverticuli. Physical and neurological development may be delayed or abnormal, and some individuals may have dysmorphic features, skeletal abnormalities, or congenital brain malformations. Skin characteristics similar to those seen in cutis laxa may also be present in arterial tortuosity syndrome5 or occipital horn syndrome.
