The WNT10A mutation has been described in various ED syndromes.4-6 In 2007, Adaimy et al9 were the first authors to relate a homozygous mutation in the WNT10A gene to OODD and, in 2009, Bohring et al10 were the first to describe SSPS in patients with WNT10A mutations. This evidence concerns the gene WNT10A and Schöpf-Schulz-Passarge syndrome.
