- Four common variants in ANXA11 (rs113772135, rs2789686, rs1079242, rs61860017) were significantly associated with TDP-C and replicated in independent cohorts.
- Rs1079242-A showed the strongest replication and correlates with higher ANXA11 levels in CSF, suggesting potential as a CSF biomarker.
- No significant associations were found between TARDBP variants and TDP-C.
- AI-guided rare variant analysis identified a pathogenic variant in FIG4, a gene linked to ALS.
- Mendelian randomization indicated that ALS genetic load is associated with increased TDP-C risk, hinting at a genetic overlap.
- ANXA11 and FIG4 are both involved in the inositol pathway, offering new mechanistic insights into TDP-C.
