The affected skin may be thickened and dark.


Abnormal skin may give affected individuals and children a prematurely-aged appearance and they can potentially look much older than their true sindrome de barsy.

Unlike similar skin disorders, easy bruising and scarring are generally not associated with cutis laxa.

The joints are sindrome de barsy abnormally loose hypermobility because of lax ligaments and tendons. Several inherited forms of the disorder have been identified. Sindrome de barsy cases are inherited as either an autosomal dominant or recessive disorder.

Ehlers-Danlos syndrome EDS is a group of hereditary connective tissue disorders characterized by defects of the major structural protein in the body collagen.

Collagen, a tough, fibrous protein, plays an essential role in holding together and strengthening the tissues of the body.

Due to defects of collagen, primary EDS symptoms and findings include abnormally flexible, loose joints articular hypermobility that may easily become dislocated; unusually loose, thin, stretchy elastic sindrome de barsy and excessive fragility of the skin, small blood vessels, and other bodily tissues and membranes.
