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). The gene discussed is SLC13A3; the disease is Parkinson disease.
