The 420K LEKTI variant alters LEKTI proteolytic activation and results in protease deregulation: implications for atopic dermatitis

Abstract excerpt

Lymphoepithelial Kazal-type related inhibitor (LEKTI) is a multidomain serine protease inhibitor which plays a central role in skin permeability barrier and allergy. Loss-of-function mutations in the LEKTI encoding gene SPINK5 cause Netherton syndrome, a rare and severe genetic skin disease with a profound skin barrier defect and atopic manifestations. Several studies also reported genetic association between the...
