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, and understand the clinical spectrum of defects in these disorders. Currently, we have begun a study to identify the genetic factors that influence the variation in liver disease severity seen in this disorder.

We are working on understanding the molecular basis of the clinical features observed in patients with ring chromosome 20 syndrome. We are working with Dr. Harold Riethman to clone the fusion points of the ring chromosomes to determine the mechanism of formation, and develop a molecular diagnostic test. We are looking to determine the mechanism by which ring chromosomes lead to human disease, especially for those rings with no deletions or duplications.

We have recently begun to utilize SNP array technology to identify genomic alterations associated with several phenotypes including biliary atresia, fetal death, and a variety of clinical abnormalities diagnosed in infancy or early childhood. We are interested in defining the range of genomic abnormalities that are disease causing.


Rotation Projects for 2009-2010

(possible examples, exact projects subject to discussion with PI)

1. Cloning of fibroblasts from a chimeric XX/XY individual suspected of having the XX cell line derived maternally (uniparental inheritance).
2. Expression analysis of chromosome 20 genes in cells from ring 20 patients.
