As expected, when compared to control‐like subtypes (S1 and S2), the AD‐like subtypes (S4, S5, and S6) had higher levels of M5 (Glycolysis/Neuronal) and M4 (Ubiquitination), which have the strongest correlations to tau and amyloid biomarkers in CSF (Figure 4). Here, MAPT is linked to Alzheimer disease.
