Loss of nuclear TDP-43 in ALS motor neurons first manifests as aberrant inclusion of the STMN2 cryptic exon 2a, producing a truncated non-functional STMN2 protein that impairs microtubule repair at the axon. This splicing defect precedes detectable cytoplasmic TDP-43 aggregation by at least 48h in iPSC motor neurons subjected to TDP-43 depletion, establishing STMN2 cryptic exon inclusion as the earliest measurable loss-of-function event. Restoring STMN2 function with antisense oligonucleotides s
RNA-binding protein condensate maturation from reversible phase separation to amyloid-like aggregation should produce a measurable proximal phenotype before late disease pathology. The decisive test is time-resolved iPSC motor-neuron perturbations combining RNA stoichiometry, PTM mapping, live-cell condensate tracking, and cryo-electron tomography.
