Descriptive Information
Brief Title † Longitudinal Natural History Study of Patients With Peroxisome Biogenesis Disorders (PBD)
Official Title † Longitudinal Natural History Study of Patients With Peroxisome Biogenesis Disorders (PBD)
Brief Summary The Peroxisome Biogenesis Disorders (PBD) are a group of inherited disorders due to defects in peroxisome assembly causing complex developmental and metabolic sequelae. In spite of advancements in peroxisome biology, the pathophysiology remains unknown, the spectrum of phenotypes poorly characterized and the natural history not yet systematically reported. Our aims are to further define this population clinically, biochemically and genetically. The investigators will prospectively follow patients from Canada, the US and internationally, and collect data from medical evaluations, blood, urine and imaging studies that would be performed on a clinical care basis. Patients unable to attend clinics can participate in this study by mailing in their medical information. The investigators will use this information to identify standards of care and improve management.
Detailed Description Participants have the option to be seen in consultation at the McGill University Health Centre in Montreal, Canada, on a yearly basis. This includes a consultation in Genetics, Nutrition, Neurology, and Ophthalmology (OCT and FAF exams). All medical records and images will be collected, retrospectively and prospectively, until the end of the study, and entered anonymously in a database. Molecular testing (through next-generation panel of 75 genes) will be offered to participants whose mutations have not been identified yet. Biospecimens will be collected to identify new biomarkers. Drug screening will be performed on cultured fibroblasts.
