a hereditary predisposition to allergic disease. The manifestations may be allergic rhinitis, allergic asthma*, atopic eczema or some form of food allergy*.

An inherited tendency to develop an allergic condition, such as asthma or eczema.

is a greek word meaning 'a strange disease'. Modern usage tends to confine it to IgE mediated allergic responses. Most often manifested as a skin or mucous membrane response as against a generalised body response. An atopic individual is generally considered to be a person who has a genetic disposition to allergy.

The genetically determined tendency to be allergic to things.

an allergic reaction that becomes apparent in a sensitized person only minutes after contact

Allergy-induced itchiness

A predisposition to develop allergy, which may remain latent until clinical allergy develops.

Atopy is an inherited, familial tendency to develop some form of allergy such as hay fever, asthma, eczema.

the hereditary predisposition to develop allergies such as asthma, hay fever (or pollinosis), urticaria, eczema (so called "atopic" dermatitis), certain other types of rhinitis and conjunctivitis as well as different food allergy reactions.

a clinical hypersensitivity (allergic) state with a hereditary predisposition; i.e., the tendency to develop an allergy is inherited, but the specific clinical form (hay fever, asthma, etc.) is not.

A genetic susceptibility to produce IgE antibodies directed toward common environmental allergens.

natural or inherited hypersensitiveness to certain allergens. The term covers diseases such as hay fever, asthma, and eczema where there is a family history.

A hereditary tendency to develop allergies (allergic rhinitis, allergic asthma, eczema).

Type of allergy where levels of the antibody immunoglobin E are increased; atopy includes rhinitis, asthma, hay fever and eczema.

Hypersensitivity to environmental allergens, a common cause of face rubbing or paw licking in dogs.

An allergic reaction with strong family history

The inherited tendency to develop allergies. The three major atopic diseases are atopic rhinitis, atopic asthma, and atopic dermatitis (see Allergies).

A term used by allergists to describe IgE-mediated anaphylactic responses in humans, usually genetically determined.

A tendency to develop allergic reactions (asthma, eczema, hay fever, etc.) to certain plant or animal substances. This is due to the production of antibodies (immunoglobulin E) against these last.

Allergic reaction by the body originating from genetics.

The state of having one or more of a defined group of diseases-allergic rhinoconjunctivitis, allergic asthma, and atopic dermatitis-that are caused by a genetic propensity to produce immunoglobulin E (IgE) antibodies to environmental allergens encountered through inhalation, ingestion, and possibly, skin contact. A broader definition, sometimes used for epidemiologic studies, requires only the presence of IgE antibody, regardless of allergic disease.

A predisposition to allergy that's inherited from parents. Included disorders are asthma, hay fever and eczema.

The clinical manifestation of Type I hypersensitivity reactions including eczema, asthma, rhinitis and food allergy.

Atopy (Greek ατοπία - placelessness) or atopic syndrome is an allergic hypersensitivity affecting parts of the body not in direct contact with the allergen. It may involve eczema (atopic dermatitis), allergic conjunctivitis, allergic rhinitis and asthma. There appears to be a strong hereditary component.
