Zea m 14 is a lipid transfer protein (LTP).

Syndromes

Maize allergy is seen in conjunction with allergies to other foods presenting as Latex Food Syndrome, which is caused by the body confusing the proteins it encounters in food to that of latex proteins to which it is already sensitised.

LTP's are a group of proteins which can cause more serious allergic reactions in patients, you may suffer from LTP Syndrome if you suffer IgE type allergy symptoms to foods mentioned in the cross reactivity section below.
