particularly, CpG islands are common for housekeeping genes, significant for regular mobile features. Hypermethylation, a rise in methylation relative to normal, of CpG islands silences gene expression and the alternative is usually real; hypomethylation promotes gene expression. Methylation status

The PEMT gene encodes an enzyme important for creating phosphatidylcholine, a important ingredient of cell membranes and lipoproteins. Mutations in PEMT can disrupt phosphatidylcholine synthesis, potentially affecting liver function, lipid metabolism, and brain health and fitness. signs or symptoms
