Mowat-Wilson syndrome is a recently delineated autosomal dominant developmental anomaly, whereby heterozygous mutations in the ZFHX1B gene cause mental retardation, delayed motor development, epilepsy and a wide spectrum of clinically heterogeneous features, suggestive of neurocristopathies at the cephalic, cardiac and vagal levels. However, our understanding of the etiology of this condition at the cellular level remains vague. This study presents the Zfhx1b protein expression domain in mouse embryos and correlates this with a novel mouse model involving a conditional mutation in the Zfhx1b gene in neural crest precursor cells. These mutant mice display craniofacial and gastrointestinal malformations that show resemblance to those found in human patients with Mowat-Wilson syndrome. In addition to these clinically recognized alterations, we document developmental defects in the heart, melanoblasts and sympathetic and parasympathetic anlagen. The latter observations in our mouse model for Mowat-Wilson suggest a hitherto unknown role for Zfhx1b in the development of these particular neural crest derivatives, which is a set of observations that should be acknowledged in the clinical management of this genetic disorder.
