Silvia and Rodrigo are joined by Dr Ray Wang, Director of the multidisciplinary Foundation of Caring Lysosomal Storage Disorder Program at the Children's Hospital of Orange County. Silvia asks Dr Wang and Rodrigo (who also happens to be a researcher in this field) about cutting-edge advances in LSD research: from base editing in Pompe disease and patient-specific in vivo gene editing, to new biomarkers and scoring systems in Gaucher disease, insights into lipid dysregulation across lysosomal storage disorders, and the first clinical trial of anakinra in Sanfilippo syndrome.

Papers discussed include:
