Abstract

Ectodermal dysplasias are a group of genetic disorders defined by ectodermal derivative impairment (EDI). To test the impact of the Wnt/beta-catenin pathway in the genetic screening of EDI, we performed a molecular gene study of WNT10A in 60 subjects from a population of 133 young Italian patients referred for the impairment of at least one major ectodermal-derived structure and who had a previous negative molecular screen for ectodysplasin signaling pathway genes ED1, EDAR, and EDARADD. Fourteen WNT10A mutations were identified in 33 subjects (24.8%), 11 of which were novel variants. The phenotype was evaluated through a detailed clinical examination of the major and minor ectodermal-derived structures. This study is the first to show that, after ED1, WNT10A is the second molecular candidate for EDI in a large Italian Caucasian population. The study confirmed that Phe228Ile is the most frequent WNT10A variant in Caucasian populations, and that WNT10A mutations are associated with large variability in EDI.
