Description of Research
Our lab is interested in identifying genes that contribute to congenital disease. We have a long-standing interest in Alagille syndrome, a genetic disorder that affects the heart and liver. We have demonstrated that this disorder is caused by two genes in the Notch Signaling Pathway, and have continued to study the effect of these mutations, seeking to understand the clinical spectrum of defects in these disorders. Currently, we are looking to identify the genetic factors that modify the clinical variation present in this disease.
In addition to our work on Alagille syndrome, we are funded to investigate the genetic susceptibility to Biliary Atresia (BA). Various research efforts are underway, including GWAS and whole exome sequencing of individuals and trios. Using these techniques, we are exploring several genes that may contribute to the etiology of BA.
We are working on understanding the molecular basis of the clinical features observed in patients with Ring Chromosome 14 Syndrome and Ring Chromosome 20 Syndrome. To achieve this goal, we are exploring a number of different research strategies, including iPS cell work. By characterizing the rings, we hope to identify the mechanism by which ring chromosomes lead to human disease and the characteristic seizure phenotype.
In colloboation with Dr. Ian Krantz, we lead a program project grant to test the applications of whole exome sequencing to 5 pediatric disorders, as well as to explore the ethical and psychosocial implications of this work.
