Types In 2017, 13 subtypes of EDS were classified using specific diagnostic criteria. According to the Ehlers–Danlos Society, the syndromes can also be grouped by the symptoms determined by specific gene mutations. Group A disorders are those that affect primary collagen structure and processing. Group B disorders affect collagen folding and crosslinking. Group C are disorders of structure and function of myomatrix. Group D disorders are those that affect glycosaminoglycan biosynthesis. Group E disorders are characterized by defects in the complement pathway. Group F are disorders of intracellular processes, and Group G is considered to be unresolved forms of EDS.
