Neither TDP‐43 nor t‐tau levels showed any plasma‐CSF correlation in either of the groups (TDP‐43 in the ALS group: P = 0.2279, TDP‐43 in the control group: P = 0.9252, t‐tau in the ALS group: P = 0.1024, t‐tau in the control group: P = 0.3463) (Fig. S2A and C). Here, TARDBP is linked to amyotrophic lateral sclerosis.
