Within the DE-mRNAs are factors that are clearly related to neuronal development (NID2, VIM, NTN1, SEMA3, EYA1, CDH19), brain transport and neurotransmission (SLC13A3, SLC6A20, SLC6A12, MOCOS, TRPM4, KCNJ13, CUBN, MRASAL1), brain injury (FN1, BHMT2, PATL2, GDF10, GSN, FGL2, OTOF, VCAM1, PROS1, COL4A5, EFEMP1, NPFFR2, LAMA2, ADAM12, MYOF) and neurodegenerative diseases associated with Al like AD (ND6, STOML2, MRC1, KDR, NEIL2), Parkinson Disease (PD) (ATP13A5, HIST1H1C) and Amyotrophic Lateral Sclerosis (ALS) (ANXA2) (Fig. 3b). This evidence concerns the gene SLC6A20 and neurodegenerative disease.
