Heterozygous GBA1 loss of function reduces beta-glucocerebrosidase activity, disrupts lysosomal lipid handling, and promotes alpha-synuclein accumulation through a feed-forward lysosomal stress loop. The most actionable therapeutic strategy is GCase restoration or substrate correction in genotype-enriched GBA1-PD rather than broad TFEB activation alone.
C9orf72 hexanucleotide repeat expansion produces repeat RNA foci and RAN-translated dipeptide-repeat proteins that disrupt nucleocytoplasmic transport, translation, stress granules, and neuronal survival. The strongest program should not be DPR-only; it should separately interrogate sense RNA, antisense RNA, DPRs, and C9orf72 haploinsufficiency.
