A method of identifying a subject falling within a new patient population characterised by eosinophil IgE mediated allergic inflammation, involving analysing the level of methylation in a DNA sample obtained from the subject for one or more promoter regions associated with one or more genes. Individuals within this new patient population are expected to be likely to respond to therapies for eosinophil IgE mediated inflammation, such as inhibitors of IL-5, IL-13, IgE or M1 prime activity and other therapies directed towards eosinophils.
