Intestinal malrotation occurs in as many as 1 in 500 human births (0.2% of the population) and poses significant risk for life-threatening complications in babies and children. No clear inheritance pattern has been identified for intestinal malrotation, suggesting a multifactorial etiology involving genetic, epigenetic and/or environmental causes.

Normal digestive anatomy is a consequence of the dramatic elongation, left-right asymmetric looping and rotation of the primitive gut tube during fetal development, but the cellular and molecular mechanisms underlying these events in gut morphogenesis are poorly understood.

Our lab employs chemical genetic strategies in amphibian embryos to investigate the mechanisms of digestive tract morphogenesis, understand the etiology of intestinal malrotation, and define the effects of chemicals and toxins on gut development.
