Mapping the disease impacts of rare DNA variation using patient and population-scale multiomics. We develop and apply computational and statistical tools to uncover pathogenic variants in undiagnosed rare diseases. We work with multi-disciplinary researchers, patients and families within the Genomic Answers for Kids program at Children's Mercy Hospital. Our lab uses genomic data (short- and long-read), bulk and single-cell functional profiles, and phenotypic resources from across the spectrum of human diseases in both differentiated and pluripotent cellular contexts. These insights - drawn from clinical samples to population-scale biobanks - allow us to pinpoint causal disease genes, pathways, and regulatory mechanisms underlying rare disease phenotypes, enabling expanded patient genome assessment.
