Professional Interests
- Translational and clinical research focused on inborn errors of metabolism and skeletal dysplasia
Professional Statement
My research interests are focused on translational medicine, specifically, evaluating new and potential therapies for various genetic disorders. I am particularly interested in conducting natural history studies, proof-of-concept pilot studies, and interventional clinical trials in patients with inborn errors of metabolism and skeletal dysplasias.
As the Co-PI for the NIH Rare Disease Clinical Research Network’s Urea Cycle Disorders Consortium, I am actively involved in conducting natural history studies, data-mining projects, and exploratory studies aimed at improving therapies for UCDs. We recently discovered that some distinct features of UCDs could be a result of perturbations of non-ureagenic functions of urea cycle enzymes. In particular, we have shown that nitric oxide (NO) deficiency in the UCD argininosuccinate lyase deficiency (ASLD) contributes to the phenotype of the disorder. We are now translating these molecular findings into the clinical realm by performing clinical trials to evaluate the effects of NO supplementation on vascular and neurocognitive parameters in ASLD.
Another research area of interest is in regards to osteogenesis imperfecta (OI), a heritable form of brittle bone disease. We were the first group to show efficacy of anabolic bone therapy in milder forms of OI. BCM is the primary site for the Brittle Bone Disease Consortium, a newly funded RDCRN Consortium site. We are actively involved in conducting natural history studies in OI to answer clinically relevant questions. In addition, I am the Lead Investigator in a Phase I/II study evaluating the safety and efficacy of TGF inhibition in subjects with severe forms of OI.
Clinical Interests
As an adult clinical geneticist, I provide clinical care for adult patients with a wide variety of heritable conditions. I serve as the Director of the Clinic for Metabolic and Genetic disorders of bone that caters to adult subjects with OI, heritable disorders of bone, early-onset osteoporosis, and other common forms of metabolic bone diseases.
