Discover the latest advancements in Morquio B research. Our dedicated team is committed to unlocking new insights, developing treatments, and improving outcomes for those affected by this disease.

Research Study for the Development of a Core Outcome Set for Morquio B and GM1 Gangliosidosis

Interested in sharing your experiences with Morquio B and connecting with others in the community? Please consider participating in virtual focus groups hosted by the BC Children’s Hospital Research Team. This is part of a new research study for the development of a Core Outcome Set for Morquio B and GM1 Gangliosidosis.

The aim of this project is to gather the stories and lived experiences of patients and caregivers within the Morquio B and GM1 gangliosidosis community to create a core list of medical and quality-of-life outcomes. Our team wishes to empower individuals from the community to take part in research that is meaningful to them. It is just as important and necessary for researchers to learn information about what is impactful to people with Morquio B as it is to research medical symptoms and issues. Developing a list of outcomes will allow future clinical trials to align better with the interests of the Morquio B community and health professionals. This is a continuation of the previous research projects on the natural history of Morquio B and GM1 supported by the Priest Family Fund for Morquio B.

Currently, we are inviting members from the international community to join our focus group sessions to discuss their experiences with us, and to share what they consider to be helpful treatment end goals.

Morquio B Disease (MBD) is a rare genetic disorder with less than 50 patients known worldwide. Together with international experts in MBD and patient partners, Dr. Sylvia Stockler (Head Division Biochemical Diseases, BCCH) and Dr. Antony Cooper (Pediatric Limb Reconstruction surgeon) are conducting a prospective observational Natural History Study to determine measurable outcomes for the anticipated clinical trial of small chaperone molecule as a potential causative treatment for patients with MBD

Research Team

Dr. Sylvia Stockler

Dr. Stöckler is a pediatrician and biochemical (metabolic) geneticist with experience in the treatment of children with Morquio B Disease and GM1-gangliosidosis, and is especially interested in the development of core outcomes sets (COS) and patient meaningful outcomes (PMO) for rare disease conditions. She works at the British Columbia Children’s Hospital (University of British Columbia) as well as the Research Institute, Canada. Dr. Sylvia Stöckler is currently the principal investigator for the project aimed at developing a COS for Morquio B and GM1 gangliosidosis (juvenile and late-onset). In addition to Morquio B Disease, Dr. Stöckler has also aided in the development of a COS for creatine transporter deficiency (CTD) and guanidinoacetate methyltransferase (GAMT) deficiency.

Dr. Anthony Cooper

Dr. Anthony Cooper is an Orthopaedic Surgeon and Head of the Department of Pediatric Orthopaedics at BC Children’s Hospital (BCCH) as well as a Clinical Associate Professor of Orthopaedics at the University of British Columbia (UBC).
Dr. Cooper treats a multitude of complex congenital and acquired limb deformities including Fibular Hemimelia, Tibial Hemimelia, Congenital Femoral Deficiency, Legg-Calve-Perthes (Perthes) Disease, Osteogenesis Imperfecta and Morquio-B. His clinical practice focuses on limb lengthening and reconstructive surgery. His research interests range from studies involving paediatric hip, lower limbs, feet, trauma, and bone tumours. By studying both clinical outcomes and patient reported outcomes, he investigates the effectiveness of treatments he uses in his clinic and to explores ways to improve the quality of life of his patients.
Dr. Cooper is the founder of the International Limb Differences Network (ILDN), an international network of healthcare professionals and researchers whose main objective is improving the quality of life for children with limb differences. Dr. Cooper has also co-lead the development of Limb-Q kids, an internationally applicable patient-reported outcome measure for children with lower limb differences.

Zahra Nasseri Moghaddam is a research assistant at the Biochemical Genetics Clinic at BC Children’s Hospital, with her research primarily focusing on rare diseases. In her capacity as a primary researcher, she has collaborated with the Association for Creatine Deficiencies (ACD) to develop a core outcome set (COS) for creatine transporter deficiency and guanidinoacetate methyltransferase deficiency. She is currently leading manuscript preparation for the study. She is also involved in several other projects related to metabolic and neurodevelopmental disorders. She is currently working on developing a COS for Morquio B and GM1 gangliosidosis.

Jasmine Li is a research assistant at the Biochemical Genetics Clinic at BC Children’s Hospital, with a special interest in rare diseases involving medical nutrition therapy. Jasmine is the leading researcher responsible for data collection, analysis and manuscript writing for a retrospective study investigating age-dependent phenylalanine tolerance. She was also the secondary researcher involved in developing (COS) for (CTD) and GAMT deficiency. Jasmine is also one of the core researchers working on the development of a COS for Morquio B and GM1 gangliosidosis.

Maria Bleier is a research assistant at the Biochemical Genetics Clinic at BC Children’s Hospital, with research topics focusing on rare disease progression over the lifespan. As one of the primary researchers for the Morquio B Patient Caregiver Survey, she was responsible for the research work and publication of this project. This survey was only possible with the continued collaboration, funding, and support from the MorquioBetter Project, Tina Priest and her family, as well as the international Morquio B Community. Maria will continue in her capacity as one of the researchers working on the development of a COS for Morquio B and GM1 gangliosidosis.
