The importance of analyzing the protein aggregates for each neurodegenerative disease can be highlighted by a recent study by Pires and colleagues who demonstrated that Secernin 1 co‐localizes with p‐Tau in cases of AD but not other Tauopathies including PiD, CBD, or PSP (Pires et al., 2019). This evidence concerns the gene SCRN1 and Alzheimer disease.
