MTA2 and tauopathy: Indeed, while we observed that some individual variants had morphological findings that resembled sporadic tauopathies (i.e. L266V, L315R with sporadic PiD, a subset of P301L with sporadic GGT; Table 2), most individual patient samples and variant groups included additional various glial and neuronal morphologies that did not entirely match findings typical for sporadic tauopathies [13, 43].
