While infants with FPIAP to cow's milk obviously cannot tolerate cow's milk in the earliest weeks of life, the concept of reintroduction at the earliest timepoint possible, in the most tolerable form for that timepoint (baked ingredient or partially hydrolyzed formula, for example) would likely be very important to mitigate the risk of developing IgE-mediated food allergy. The gene discussed is IGHE; the disease is food allergy.
