Embryology and genetics of human malformation

Our research program is aiming to identify genes or non- coding genomic alterations responsible for congenital malformations and answer important questions in clinics, biology and developmental genetics. We have a special interest for tissues derived from the neural crest (neurocristopathies), and ciliopathies.

The neural crest is a transitory embryonic structure that participates to the development of many structures. We have a long lasting interest on the development of the enteric nervous systems and Hirschsprung disease, a model for complex oligogenic and sex-dependent inheritance.

In collaboration with many reference centers for rare diseases on the Necker Hospital campus we also developed research projects on craniofacial (especially mandibulofacial dysostoses), syndromic deafness and cardiac malformations through NGS, in vitro and in vivo analysis in zebra fish and mice.

Ciliopathies are a fast growing group of diseases that are the consequence of an abnormal genesis or functioning of the motile and/or primary cilia. Our work on ciliopathies contributes to the understanding of primary cilium formation and links extreme lethal phenotypes with viable syndromes. A recent focus has been made on corpus callosum agenesis, the most frequent brain malformation, as well as brain neuronal migration defect.
