Main Interests:

Birth defects occur in approximately five percent of newborns, and there are more than 700 inherited conditions with craniofacial abnormalities. The research focus of Dr. Jabs' laboratory is to increase our understanding of the molecular basis of human developmental malformations, especially craniofacial disorders such as Crouzon, Apert,and Treacher Collins syndromes. Mutations for craniosynostosis and mandibulofacial dysostosis conditions were identified in homeobox and helix-loop-helix transcription factors and growth factor receptors. Current experimentation involves gene expression and protein interaction studies in animal model, biochemical and cellular systems. These studies are elucidating the pathogenetic mechanisms of these mutations, signaling pathways involved in normal and abnormal developmental processes, and phenotype-genotype correlations.
