Research Interests

Congenital anomalies are the leading cause of infant mortality in the United States, accounting for more than 20% of all infant deaths, yet the causes of about 70% of all birth defects are still unknown. My lab is involved in studies of craniofacial genetic syndromes and structural birth defects, such as craniosynostosis, bladder epispadias-exstrophy complex, and cleft lip and/or palate. Our ultimate goal is to identify genes and environmental factors contributing to the risk of these birth defects. Through the International Craniosynostosis Consortium we have recruited and evaluation more than 800 families with craniosynostosis. We have performed genome-wide association studies and identified BMP2 and BBS9 as craniosynostosis candidate genes (Justice et al 2012). Using whole exome sequencing we recently identified autosomal recessive mutations in a gene causing complex craniosynostosis. The current focus of my laboratory is to characterize the role of these genes by using molecular genetics, cell biology, and animal models approaches.
