Focal dermal hypoplasia (FDH, Goltz syndrome), is an X-linked dominant mesoectodermal developmental disorder, involving skin, skeleton, eyes, teeth, and other organs. Mutations in PORCN, which stimulates the secretion of wingless family signal proteins, are found in FDH patients. A female fetus presented at 34 weeks gestation with interuterine growth restriction (IUGR), asymmetry, limb anomalies, microphthalmia, and lung anomaly. Focal dermal hypoplasia was confirmed at birth, with hypoplastic areas of skin, malformation of the limbs, diaphragmatic hernia, and ocular anomalies. Mutation analysis of PORCN revealed a nonsense mutation-Y359X. She presented natal teeth, an unexpected feature considering the role of the Wnt pathway in tooth development.
