Thirty of the most significant DMPs associated with immune genes grouped according to their GO function. The y-axis represents the β-value for each position (purple for 12 months, green for 24 months). Red squares indicate CpGs with hypermethylation at 24 compared with 12 months samples, while for the remaining CPGs, hypomethylation was found at 24 compared with 12 months of age
