Prenatal diagnosis of lamellar ichthyosis can be achieved by electron microscopic examination of fetal skin biopsies or amniotic fluid cells obtained via fetoscopy. DNA-based molecular genetic testing is commercially available for TGM1, ABCA12, ALOXE3 and ALOX12B.

How do you test for ichthyosis?

A doctor can often make a diagnosis by examining the affected skin and the characteristic scales. He or she may perform other tests, such as a skin biopsy. This may be necessary to rule out other causes of dry, scaly skin.
