Abstract:
Facioscapulohumeral dystrophy (FSHD) is a unique and complex genetic disease that is not entirely solved. Recent advances in the field have led to a consensus genetic premise for the disorder, enabling researchers to now pursue the design of preclinical models. In this review we explore all available FSHD models (DUX4-dependent and -independent) for their utility in therapeutic discovery and potential to yield novel disease insights. Owing to the complex nature of FSHD, there is currently no single model that accurately recapitulates the genetic and pathophysiological spectrum of the disorder. Existing models emphasize only specific aspects of the disease, highlighting the need for more collaborative research and novel paradigms to advance the translational research space of FSHD.
Insights
Facioscapulohumeral dystrophy (FSHD) research is advancing with new preclinical models. However, no single model fully captures FSHD
Area of Science:
- Genetics
- Neuromuscular Disorders
- Disease Modeling
Background:
- Facioscapulohumeral dystrophy (FSHD) is a complex genetic disorder with an evolving understanding of its genetic basis.
- Recent progress has established a consensus genetic premise, paving the way for preclinical model development.
Purpose of the Study:
- To review and assess existing DUX4-dependent and -independent FSHD models.
- To evaluate their utility for therapeutic discovery and gaining new disease insights.
Main Methods:
- Comprehensive review of current FSHD preclinical models.
- Analysis of model relevance to FSHD genetics and pathophysiology.
Main Results:
- No single existing model fully recapitulates the genetic and pathophysiological spectrum of FSHD.
- Current models highlight specific disease aspects but are not comprehensive.
Conclusions:
- Existing FSHD models are valuable but limited in scope.
- Collaborative research and novel approaches are crucial for advancing FSHD translational research.
