Significant decrease in mRNA expression of myelin transcription factor (MYRF) (p= 0.028), OLIG2 (p=0.009), SOX10 (p=0.02), NKX2-2 (p=0.032), transferring (TF) (p=0.5), proteolipid protein 1 (PLP1) (p=0.040), myelin basic protein (MBP) (p=0.061), myelin-associated oligodendrocyte basic protein (MOBP) (p=0.019), oligodendrocyte glycoprotein (MOG) (p=0.05), Mal T-cell differentiation protein (MAL) (p=0.039), myelin associated glycoprotein (MAG) (p=0.035), and 2',3'-cyclic nucleotide 3' phosphodiesterase (CNP1) (p=0.017) was seen in frontal cortex in ALS cases compared with controls (Figure 4). This evidence concerns the gene MOG and amyotrophic lateral sclerosis.
