What causes Ehlers-Danlos syndrome, dermatosparaxis type? Ehlers-Danlos syndrome (EDS), dermatosparaxis type is caused by changes (mutations) in the ADAMTS2 gene. This gene encodes an enzyme that helps process several types of "procollagen molecules" (precursors of collagen). Collagen is a protein that provides structure and strength to connective tissues throughout the body. Mutations in ADAMTS2 lead to reduced levels of functional enzyme which interferes with the proper processing of procollagens. As a result, networks of collagen are not assembled properly. This weakens connective tissues and causes the many signs and symptoms associated with EDS, dermatosparaxis type.
