Our research focuses on the development of gene and cell-based therapies for the treatment of metabolic diseases of the liver that commonly result in the development of intellectual disabilities in children. We have four active research directions:
- Development of gene-based (adeno-associated virus, mRNA) therapies to restore nitrogen metabolism, ureagenesis, and creatine biosynthesis.
- Exploring the underlying neurobiology in arginase deficiency and in guanidinoacetate methyltransferase deficiency to gain a greater understanding of the neuropathology that exists in these enzyme deficiencies.
- Developing new therapeutic approaches to treating deficiency of carbamoyl phosphate synthetase 1.
- Understanding the effect of guanidinoacetate on GABA-A receptors in guanidinoacetate methyltransferase deficiency.
