Explore the molecular mechanisms under investigation in spinal muscular atrophy, from SMN biology and neuromuscular junctions to axonal transport and cellular metabolism. Each research axis connects specific findings with the studies behind them, their biological context and the questions that remain open.

Structural predictions, molecular simulations and experimental observations provide different kinds of evidence. Study-specific limitations are stated alongside each finding. Connections between research axes support navigation and do not imply a demonstrated causal pathway.
