The Webb Lab

The Webb Lab is located within the West Wedge of the Wisconsin Institute for Medical Research in the Center of Human Genomics and Precision Medicine.

The Webb Lab is interested in diagnosing and characterizing undiagnosed and rare diseases that primarily affects pediatrics patients. Working in tandem with the Undiagnosed Disease Program at the University of Wisconsin - Madison, we incorporate next generation 'omics in identifying pathogenic variants in undiagnosed/rare diseases. We model these diseases in cellular and animal models to better understand the pathophysiology of such diseases.​
