Researchers at the Centre de recherche Azrieli du CHU Sainte-Justine have developed the first mouse model that accurately replicates a rare genetic encephalopathy caused by mutations in the DHDDS gene. This model reproduces the human form of the disease, providing scientists with a tool to study the biological mechanisms of this severe neurodevelopmental disorder. The breakthrough was achieved by a team led by Professor Alexey Pshezhetsky and Dr. Elsa Rossignol from the University of Montreal.


This mouse model will enable researchers to investigate the underlying mechanisms of DHDDS-related encephalopathy and accelerate the development of therapeutic strategies for this rare condition. The tool provides an essential platform for testing potential treatments that could benefit patients suffering from this severe genetic disorder.

A team at the Centre de recherche Azrieli du CHU Sainte-Justine has reached a major milestone in understanding a rare and severe form of genetic encephalopathy associated with the DHDDS gene. By developing the first mouse model that faithfully reproduces one of the human forms of the disease, researcher Alexey Pshezhetsky, a professor in the Department of Pediatrics, and Dr. Elsa Rossignol, a professor in the Department of Neuroscience, both at UdeM, provide the scientific community with an unprecedented tool to investigate the biological mechanisms underlying this neurodevelopmental disorder and accelerate the development of new therapeutic strategies.
