Exploring Genetic and Epigenetic Interplay: Novel Therapeutic Targets for Disability Management

Résumé fourni par la source

Disabilities result from a complex interaction of genetic, epigenetic, and environmental factors, each contributing in unique and often overlapping ways to health outcomes. Despite significant advances in genetic research that have clarified the roles of both clearly pathogenic and clinically uncertain variants in disease causes, consistent application of these findings in clinical practice remains a significant challenge. Modifiable factors such as diet, lifestyle, and exposure to toxic environmental agents can either exacerbate underlying genetic vulnerabilities or help mitigate overall risk. This highlights the importance of adopting a truly integrative and holistic approach to understanding and addressing disability and related disorders. This review examines how genetic variants interact with epigenetic mechanisms, including DNA methylation, histone modifications, and various non-coding RNAs, to influence the onset, severity, and progression of disabilities. It also explores emerging and innovative therapeutic strategies targeting epigenetic regulators, evaluating their potential not only to alter the biological course of disease but also to improve long-term functional outcomes. Our comprehensive perspective emphasizes the dynamic and reciprocal interactions among genes, epigenetic modifications, and environmental influences, offering a unified framework for researchers and clinicians. We propose that utilizing this integrated knowledge is essential for formulating precise interventions that target underlying pathology and improve the quality of life for individuals with disabilities.
