Progress toward improved therapies for inborn errors of metabolism

Area of Science:

• Biochemistry and Genetics
• Metabolic Disorders
• Translational Medicine

Background:

• Inborn errors of metabolism (IEMs) are prevalent and severe genetic disorders lacking effective treatments.
• Expanded newborn screening necessitates urgent development of early therapeutic interventions for IEMs.
• Current treatment strategies for IEMs are insufficient, highlighting the need for novel approaches.

Purpose of the Study:

• To review and discuss emerging therapeutic strategies for inborn errors of metabolism.
• To highlight the potential of new technologies and advancements in treating IEMs.
• To address the urgent need for effective treatments driven by early diagnosis through newborn screening.

Main Methods:

• Exploration of multi-front therapeutic strategies targeting gene, RNA, protein, and cellular levels.
• Review of diverse approaches including small molecules, enzyme replacement, cell, and gene therapy.
• Assessment of novel technologies like genome editing, RNA interference, and cell reprogramming.

Main Results:

• A growing number of novel treatments for IEMs are progressing through clinical development.
• Various strategies are being employed to counteract the effects of enzyme deficiencies in IEMs.
• Advancements in both existing and new therapeutic modalities show significant promise.

Conclusions:

• New technologies and improved existing strategies offer tremendous potential for clinical translation in IEM treatment.
• The integration of gene, RNA, protein, and cell-based therapies represents a promising future for IEM management.
• Continued research and development are crucial to translate these therapeutic advancements into effective clinical practice.
