Cutis laxa, autosomal recessive, 1B
A connective tissue disorder characterized by loose, hyperextensible skin with decreased resilience and elasticity leading to a premature aged appearance. Face, hands, feet, joints, and torso may be differentially affected. The clinical spectrum of autosomal recessive cutis laxa is highly heterogeneous with respect to organ involvement and severity. ARCL1B features include emphysema, lethal pulmonary artery occlusion, aortic aneurysm, cardiopulmonary insufficiency, birth fractures, arachnodactyly, and fragility of blood vessels.
