You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments. [rarediseases.info.nih.gov]
Prognosis
Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. [rarediseases.org]
The presence of the metabolic alteration has consequences both for organ involvement, prognosis assessment and counselling. [nature.com]
Prognosis The lifespan of some patients with cutis laxa (elastolysis) may not be significantly decreased. Patients with the autosomal dominant form have a normal life expectancy. [emedicine.medscape.com]
Etiology
Next generation sequencing was performed in genetically unsolved patients with progeroid features, neurological and eye involvement to assess the underlying etiology. [scinapse.io]
In cutis laxa patients mutations have been demonstrated in elastin or fibulin genes, but in the majority of patients the underlying genetic etiology remains unknown. [nature.com]
Epidemiology
Epidemiology Cutis laxa (elastolysis) is rare. Congenital forms of cutis laxa are more common than acquired disease. The recessively inherited form is most frequent and most severe. Autosomal dominant forms also exist. [emedicine.medscape.com]

Pathophysiology Cutis laxa (elastolysis) is characterized by degenerative changes in the elastic fibers resulting in loose, pendulous skin. The skin is sagging, redundant, and stretchable, with reduced elastic recoil. [emedicine.medscape.com]
Pathophysiological aspects in ARCL type II patients with a ATP6V0A2 defect As described above, a large number of families with ARCL type II or WSS2, 22 with a distinct phenotype showed loss-of-function mutations in the a2-subunit of the V-type H+-ATPase [nature.com]
Prevention
In ARCL1A, the mutations in both copies of this gene cause an altered structure of the protein product, preventing its transport out of the cells where it is produced and into the extracellular matrix. [cutislaxa.pitt.edu]
Variants in ATP6V0A2 impair Golgi vesicle trafficking and prevent the production of functional glycosylation. This results in reduced or abnormal elastic fiber formation. [preventiongenetics.com]
Management of individuals with cutis laxa includes treatment of symptoms, such as surgical repair of hernias, medications such as beta-blockers may be considered to prevent growth of aortic aneurysms, and pulmonary emphysema is treated symptomatically [cutislaxa.org]
In addition, some subtypes of cutis laxa have only been reported in a handful of individuals, which prevents physicians from developing a complete picture of associated symptoms and prognosis. [rarediseases.org]
