Is c.1431-12G>A A common European mutation of report of a patient with Netherton Syndrome.

Netherton Syndrome (NS) is a very rare genetic skin disease resulting from defects in the gene (encoding the protease inhibitor lympho-epithelial Kazal type inhibitor 1, LEKTI1). In this report, we provide a detailed clinical description of a Polish patient with two mutations, the novel c.1816_1820+21delinsCT and possibly recurrent c.1431-12G>A. A detailed pathogenesis of Netherton Syndrome, on the basis of literature review, is discussed in the view of current knowledge about the LEKT1 molecular processing and activity.
