Biomarkers in spinal muscular atrophy

Area of Science:

• Neurology
• Genetics
• Biomarker Research

Background:

• Spinal muscular atrophy (SMA) is a severe genetic neuromuscular disorder.
• Disease-modifying therapies have transformed SMA management.
• Biomarkers are essential for diagnosis, prognosis, and treatment monitoring in SMA.

Purpose of the Study:

• To systematically review biomarkers for spinal muscular atrophy.
• To summarize classic and novel biomarkers.
• To discuss biomarker utility in clinical decision-making for SMA.

Main Methods:

• Systematic review of scientific literature.
• Analysis of biomarkers from human patients and animal models.
• Categorization of biomarkers into physiological, functional, imaging, and molecular types.

Main Results:

• Identified established biomarkers used in current SMA clinical practice.
• Highlighted emerging biomarkers from recent research.
• Discussed expression patterns, clinical correlations, and applications of various biomarkers.

Conclusions:

• Biomarkers are vital for stratifying SMA patients.
• Accurate biomarker assessment aids in predicting treatment efficacy.
• Biomarkers support individualized treatment strategies for spinal muscular atrophy.
