Emopamil binding protein mutation in conradi-hünermann-happle syndrome representing plaque-type psoriasis

Abstract

Conradi-Hünermann-Happle syndrome (CDPX2, OMIM 302960) is an inherited X-linked dominant variant of chondrodysplasia punctata which primarily affects the skin, bones, and eyes. CDPX2 patients display skin defects, including ichthyotic lesions, follicular atrophoderma, cicatricial alopecia, and less frequently ichthyosiform erythroderma, cataracts, and skeletal abnormalities consisting of short stature, asymmetric shortening of the limbs, epiphyseal stippling, and craniofacial defects. CDPX2 results from mutations in emopamil binding protein (EBP) gene. The aim of our study is to identify EBP mutation in a unique case of Conradi-Hünermann-Happle syndrome with rare psoriasiform lesions.
