Professional Interests

New genome wide technologies such as microarrays and next-generation sequencing have made it possible to uncover the cause of human disease.  Our lab focuses on human microdeletion syndromes in which affected individuals have one copy of a set of genes instead of two.  What has been particularly important is to understand why deletions occur during meiosis, identify genes responsible for the disorders and discover genetic risk factors outside deleted intervals that can explain variable phenotypes associated with such syndromes. 

 Our lab has collected over 2,000 DNA samples from individuals with the 22q11.2 deletion syndrome (22q11DS) and some of their normal parents.  The disorder is so interesting because affected individuals have behavioral disorders, craniofacial anomalies and heart defects, similar to what occurs separately in the general population.  We have performed microarray and whole exome sequencing to identify genetic modifiers of the phenotype.  A systems biology computational approach is being undertaken to integrate genotypes, known biological function of genes, exome sequence and copy number variation data to identify key genetic pathways downstream of the 22q11.2 deletion. 

In order to determine function of genes identified from the human genetics projects, we are using the mouse as a model.  Two key genes, Tbx1 and Crkl are being analyzed in mice to understand the molecular pathogenesis of cardiac, craniofacial and inner ear defects in mouse models of the disorder.  We will cross mice with mutations of these genes and genes identified from the human genetics projects to identify genetic interactions.
