Cutis laxa is a collection of disorders that are typified by loose and/or wrinkled skin that imparts a prematurely aged appearance. Face, hands, feet, joints, and torso may be differentially affected. The skin lacks elastic recoil, in marked contrast to the hyperelasticity apparent in classic Ehlers-Danlos syndrome (see 130000). These properties are nearly always attributable to loss, fragmentation, or severe disorganization of dermal elastic fibers (summary by Davidson and Giro, 2002). Autosomal dominant congenital cutis laxa (ADCL) is genetically heterogeneous and shows clinical variability. The characteristic loose skin may be accompanied by gastrointestinal diverticula, hernia, and genital prolapse. Rare manifestations are pulmonary artery stenosis, aortic aneurysm, bronchiectasis, and emphysema (summary by Graul-Neumann et al., 2008). Loose, inelastic skin is a clinical feature of many disorders, e.g., geroderma osteodysplasticum (GO; 231070) and Costello syndrome (218040). For a discussion of genetic heterogeneity of autosomal recessive cutis laxa, see ARCL1A (219100). Genetic Heterogeneity of Autosomal Dominant Cutis Laxa Also see ADCL2 (614434), caused by mutation in the FBLN5 gene (604580) on chromosome 14q32, and ADCL3 (616603), caused by mutation in the ALDH18A1 (138250) gene on chromosome 10q24.  http://www.omim.org/entry/123700
