Aside from the pathologies listed in Table 1, we did not stratify or adjust for other pathological subtypes due to missing data and/or limited variability (e.g., frontotemporal lobar degeneration with TDP-43 pathology was seen in two cases in the full sample, while frontotemporal lobar degeneration with tau pathology had 53% missing data and included two cases with progressive supranuclear palsy and none with corticobasal degeneration). Here, TARDBP is linked to progressive supranuclear palsy.
