A SACS Deletion Variant in Great Pyrenees Dogs Causes Autosomal Recessive Neuronal Degeneration
Ekenstedt et al., Human Genetics. 2023.
https://pubmed.ncbi.nlm.nih.gov/37758910/
ARSACS (autosomal recessive spastic ataxia of Charlevoix-Saguenay) is an early-onset, slowly progressive neurodegenerative disorder. To date, no naturally occurring large animal model has been reported for ARSACS. In this study, the authors describe a novel spontaneous genetic model for SACS-associated neuronal degeneration using Great Pyrenees dogs of both sexes. The canine models described in this study fit closely with the typical early‑onset ARSACS phenotype in humans, and molecular genetic studies demonstrated that these dogs exhibit a deleterious SACS mutation. The clinical and histopathological descriptions of this canine disorder contribute to the description of human ARSACS. Supported by ORIP (R01OD01027051).
Promoting Validation and Cross-Phylogenetic Integration in Model Organism Research
Cheng et al., Disease Models & Mechanisms. 2022.

Model organisms are essential for biomedical research and therapeutic development, but translation of such research to the clinic is low. The authors summarized discussions from an NIH virtual workshop series, titled “Validation of Animal Models and Tools for Biomedical Research,” held from 2020 to 2021. They described challenges and opportunities for developing and integrating tools and resources and provided suggestions for improving the rigor, validation, reproducibility, and translatability of model organism research.
