PLCG2 mRNA upregulation has been reported in cortical tissue of LOAD patients (FC, 1.35; p = 0.0028, [33]) and in transgenic mice carrying mutations associated with early AD (APP KM670/671 NL, PNSEN1 M146V) or overexpressing the human tau-4R/2N isoform (P301L) [34, 35]. The gene discussed is APP; the disease is Alzheimer disease.
