Pseudoxanthoma elasticum

What testing is available to identify unaffected carriers of pseudoxanthoma elasticum?

When considering carrier testing for unaffected relatives of individuals with pseudoxanthoma elasticum (PXE), it is most useful to begin by testing an affected family member for mutations in the ABCC6 gene. Eighty percent of individuals affected with PXE are found to have mutations in the ABCC6 gene by the genetic testing currently available. Once the ABCC6 mutations that cause PXE in a family are identified, unaffected relatives may be tested for the familial mutations to determine whether or not they are carriers.

What treatment might be available for pseudoxanthoma elasticum?

Unfortunately, there is no cure for pseudoxanthoma elasticum. Affected individuals are recommended to have regular physical examinations with their primary care physician and routine eye examinations with an eye doctor (ophthalmologist) who is familiar with retinal disorders. A team of doctors in other specialties - including dermatology, cardiology, plastic surgery, vascular surgery, genetics, and nutrition - may also help with the management this condition. Individuals should be alert to changes in their vision and should inform their eye doctor of any such changes. Several therapies may be effective for slowing the reduction in vision in PXE. Surgery may help to reduce skin symptoms, gastrointestinal symptoms, or severe vascular symptoms in the legs.
