摘要Lysosomal diseases(LDs)are a group of rare inherited disorders belonging to inborn metabolism errors.LDs are characterized by the excessive storage of undegraded substrates,most often due to the enzymatic deficiency resulting from disease-causing gene variants.LDs lead to dysregulated cellular pathways and imbalanced molecular homeostasis and can affect multiple organs and tissues.Despite being rare,LDs account for a significant incidence when considered collectively.Due to complex molecular and genetic fingerprints,considerable challenges in LD management must be overcome.Diagnosis can be signifi-cantly delayed due to the broad and nonspecific clinical manifestations and the lack of specific bio-markers.Available treatments fail to fully stop the disease progression and can alter the disease's typical phenotypes with novel manifestations.Therefore,a paradigm shift is crucial to better understand LDs and provide actionable insights.Herein,we comprehensively review the literature to demonstrate that multi-omics approaches are promising for pathophysiology elucidation,biomarker discovery,and pre-cision therapy in LDs.We recommend adopting longitudinal study designs integrated with a multi-omics-empowered framework to facilitate mechanistic delineation,biomarker discovery,and treat-ment development.Relevant approaches exploring the association between LDs and common neuro-degenerative disorders are also discussed,paving a potential path for improved therapeutic development and ultimately improving the patient's quality of life.
