NUAK1 (gene which encodes for a protein kinase), PRSS23 (gene that encodes for a serine protease of the trypsin family), and TGFBR3 (gene that encodes for the transforming growth factor (TGF)-β type III receptor) were found to have high levels of expression in the MCI group compared to the dementia group. Here, PRSS23 is linked to dementia.
