n.
a form of allergy in which there is a hereditary or constitutional tendency to develop hypersensitivity reactions (e.g. hay fever, allergic asthma, atopic eczema) in response to allergens (atopens). Individuals with this predisposition - and the conditions provoked in them by contact with allergens - are described as atopic.

at·o·py (atґə-pe) [Gr. atopos out of place] a genetic predisposition toward the development of immediate (type I) hypersensitivity reactions against common environmental antigens (atopic allergy).
