Charcot-Marie-Tooth: From Molecules to Therapy.

Area of Science:

• Neurology
• Genetics
• Molecular Biology

Background:

• Charcot-Marie-Tooth (CMT) is the most common inherited peripheral neuropathy.
• It exhibits genetic heterogeneity with autosomal dominant, X-linked, and autosomal recessive inheritance patterns.
• Numerous genes are implicated, underscoring the complexity of CMT.

Purpose of the Study:

• To review the clinical background, molecular mechanisms, and therapeutic investigations for CMT.
• To highlight research on common genetic mutations (PMP22, GJB1, MPZ, MFN2) and less common subtypes.
• To discuss the role of next-generation sequencing (NGS) in diagnosing CMT and enabling targeted therapies.

Main Methods:

• Literature review focusing on clinical presentations, genetic associations, and therapeutic research in CMT.
• Analysis of studies investigating disease-modifying treatments for prevalent CMT genetic subtypes.
• Exploration of therapeutic avenues for rarer forms of CMT.

Main Results:

• NGS has significantly improved the diagnostic yield for CMT genetic causes.
• Therapeutic research is actively pursuing treatments for common CMT mutations.
• Understanding genetic heterogeneity is crucial for developing effective, targeted therapies.

Conclusions:

• Targeted therapies are emerging for CMT, driven by advances in genetic diagnostics.
• Comprehensive understanding of CMT's molecular basis is essential for future treatment development.
• Continued research into both common and rare CMT subtypes is vital for advancing patient care.
