Raymond Wang, M.D. is the Director of the multidisciplinary Foundation of Caring Lysosomal Storage Disorder Program at CHOC and a board certified clinical geneticist and biochemical genetics specialist. Dr. Wang is aware of the challenges faced by patients and families with rare diseases such as lysosomal storage disorders. He has committed the program to provide:
- Treatment for the lysosomal disorders that have existing therapies
- Access to investigational treatment for patients with disorders that currently have no approved / effective therapy, and
- Translational research vital to development of “next generation” treatments and cures for lysosomal storage disorder patients.

As an undergraduate, Dr. Wang attended Stanford University where he was a member of the Phi Beta Kappa honors society and graduated with a bachelor’s degree with Honors and Distinction in Biological Sciences. He earned his medical degree from the University of California, Los Angeles (UCLA) where he was a member of the Alpha Omega Alpha honors society. He completed his internship and residency in medical genetics and pediatrics at Cedars-Sinai Medical Center where he served as chief resident in his final year of training. Dr. Wang completed his fellowship in biochemical genetics at the UCLA Intercampus Medical Genetics Program.
In 2006, Dr. Wang received the American College of Medical Genetics and Genzyme Fellowship in Biochemical Genetics Award. In the same year, he also received the Cedars-Sinai Medical Center’s Paul Rubenstein Prize for Excellence in Resident Research.
Dr. Wang has been named an Orange County Clinical Biochemical Genetics Physician of Excellence in 2015, 2016, 2017, and 2018. He was nominated for a 2018 Global Genes RARE Champion of Hope Award for his work with children with rare metabolic conditions.

Dr. Wang’s research concentrates upon a category of inherited conditions called lysosomal storage disorders, which result in severe, progressive multisystemic symptoms from ongoing accumulation of undegraded substrates within the lysosomal compartment of the cell. Previously untreatable and leading to early death, treatments to reduce the substrate storage such as hematopoietic stem cell transplantation and / or intravenous enzyme replacement therapy have beneficially changed the natural history of some lysosomal storage disorders.
As long-term survivors with storage disorders are becoming adolescents and young adults, progressive symptoms in other tissues resistant to these treatments have been recognized. Dr. Wang’s research focuses upon the development of treatment for these refractory organ systems, and upon the refinement of novel, non-invasive biomarkers to follow treatment progress and predict future outcomes.
