Netherton syndrome with multiple non-melanoma skin cancers.

Netherton syndrome (NS) is a rare autosomal reces-sive genodermatosis caused by SPINK-5 mutations. The SPINK-5 gene encodes the serine protease inhibitor LEKTI and is located on chromosome 5q32. Unopposed degradation of corneodesmosomes is the basis for a severely impaired skin barrier function in patients with NS. Effective treatments for patients with NS are limited. Some success has been ach...
