  Egg allergy is IgE-mediated and healthy individuals are capable of generating antigen-specific IgE upon exposure to egg allergens. It is believed that there may be a genetic component to the development of egg allergy as the progeny of atopic individuals are more likely to suffer from allergies themselves. The consensus is that IgE responses are genetically controlled by MHC-linked genes that are found on chromosome six. Other components that may be associated with atopy and allergy include the IgE Fc receptor located on chromosome eleven. […] The Gel-Coombs classification of hypersensitivity reactions is based on specific mediators of the allergic response. Egg allergy is IgE mediated, and so it is classified (like all food allergies) as a type one hypersensitivity reaction. […] IgE is the immunoglobulin responsible for egg allergy, and the IgE responses have a TH2 dependency. While TH2-derived cytokines promote IgE response, it is balanced by TH1-derived cytokine downregulation of IgE. Egg allergy can result from a failure of this balance, leading to an overproduction of IL-4 by TH2 cells.

  https://www.mayoclinic.org/diseases-conditions/egg-allergy/symptoms-causes/syc-20372115

  Eggs are one of the most common allergy-causing foods for children. […] An immune system overreaction causes food allergies. For egg allergy, the immune system mistakenly identifies certain egg proteins as harmful. When you or your child comes in contact with egg proteins, immune system cells (antibodies) recognize them and signal the immune system to release histamine and other chemicals that cause allergic signs and symptoms. […] Both egg yolks and egg whites contain proteins that can cause allergies, but allergy to egg whites is most common. It’s possible for breast-fed infants to have an allergic reaction to egg proteins in breast milk if the mother consumes eggs.

  https://acaai.org/allergies/allergic-conditions/food/egg/

  If you develop hives or other physical symptoms after eating eggs, you may have an egg allergy — one of the most common allergies, especially in childhood. […] Egg allergy develops when the body’s immune system becomes sensitized and overreacts to proteins in egg whites and/or yolks. When eggs are eaten, the body sees the protein as a foreign invader and sends out chemicals to defend against it. Those chemicals cause the symptoms of an allergic reaction. […] Experts estimate that as many as 2 percent of children are allergic to eggs. […] Children who are allergic to eggs can have reactions ranging from a mild rash to anaphylaxis, a life-threatening condition that impairs breathing and can send the body into shock. […] Eggs are one of the most common food allergens. People with an allergy to chicken eggs may also be allergic to other types of eggs, such as goose, duck, turkey or quail.

  A majority of the immunogenic proteins are found in the egg white with five major allergenic components of egg white: ovomucoid (Gal d 1), ovalbumin (Gal d 2), ovotransferrin (Gal d 3), egg white lysozyme (Gal d 4), and ovomucin. Although these are the major allergenic proteins, lipocalin-type prostaglandin D synthase and egg white cystatin have also been associated with IgE reactivity. Hen egg yolk also contains allergens, the major allergen being alpha-livetin (Gal d 5). Although Gal d 2 ovalbumin is the most abundant protein in egg white, Gal d 1 ovomucoid is the considered the dominant allergen in hen egg white. […] Egg specific IgE molecules can be classified as either sequential epitopes or conformational epitopes, the primary difference being the spatial relation between amino acids. Sequential epitopes have contiguous amino acid sequences while conformational epitopes contain amino acids in different regions of the protein structure. Individuals with egg allergies can tolerate cooked products containing eggs, suggesting that the allergic response is dependent on epitope configuration. Heat-labile allergenic proteins alter their arrangement with the cooking process, thus blunting or minimizing their immunogenic potential. In particular, ovalbumin proteins are heat-labile while ovomucoid epitopes are generally not affected by extensive heating.

  The main egg allergy proteins include: Ovomucoid. Egg whites contain ovomucoid. […] Ovotransferrin. Ovotransferrin doesn’t break down from exposure to high temperatures. You usually can’t eat raw or cooked eggs if you’re allergic to ovotransferrin. […] Ovalbumin. Ovalbumin breaks down at high temperatures, so you may be able to eat cooked eggs without developing an allergic reaction. […] Lysozyme. Around 30% of people who have an egg allergy are sensitive to lysozyme. […] An egg allergy can affect anyone. However, it’s more common in children younger than 5. Many children with an egg allergy will outgrow it as they get older and their digestive system matures.

  Egg-specific IgE molecules that identify sequential or conformational epitopes can distinguish different clinical phenotypes of egg allergy. Sequential epitopes are determined by contiguous amino acids, whereas conformational epitopes contain amino acids from different regions of the protein that are in close proximity due to the folding of the protein. Conformational epitopes can be destroyed by heating or partial hydrolysis, which alter the tertiary structure of the protein.

  Eggs are among the food allergens of animal origin and contain certain proteins that can trigger an immune response in susceptible people. The most common allergens are contained in the egg white, whereas it is much rarer for the egg yolk to trigger an allergy. […] The two main allergens are known as ovomucoid and ovalbumin. They are found in the egg white. Ovomucoid is acid resistant and heat stable. People who have an allergic reaction to ovomucoid usually cannot tolerate raw or cooked eggs. On the other hand, ovalbumin breaks down at high temperatures, so people who have an allergic reaction to ovalbumin can often tolerate cooked eggs.

  Egg allergies are caused by the bodys immune system mistakenly identifying egg proteins as a threat. […] Different parts of the egg can trigger egg allergies. […] The underlying cause of an egg allergy is the type of protein in the egg that triggers an immune response. Of the various proteins, ovalbumin is the most common in egg whites. Ovomucoid is another type of protein (and its more likely to cause a severe reaction than ovalbumin). […] Various factors will influence how likely a person is to develop an egg allergy. First, a family history of food allergies, asthma, eczema and other allergies will increase the risk of having egg allergies. Age is also a potential risk factor a childs developing immune system makes them more susceptible to allergic reactions than an adult. And finally, if a person already has atopic dermatitis or a different food allergy, they are more likely to develop an egg allergy.

  Eggs can be a great source of protein as a part of a healthy diet. But you can be allergic to some of the proteins that are found in either the egg yolk or the egg white or even both. An egg allergy, like any allergy, is when your immune system identifies these proteins as harmful. When you ingest these proteins, your immune system becomes sensitized and overreacts and releases histamines, which then cause your allergic symptoms. People with an egg allergy must avoid both the egg white and the egg yolk because its not possible to completely separate the egg white from the yolk.

  Hen’s egg allergy is the second most common food allergy in infants and young children (cow’s milk is the most common). Egg allergies are immunologic responses to proteins in foods and include immunoglobulin E (IgE) antibody-mediated allergy as well as other allergic syndromes such as atopic dermatitis and eosinophilic esophagitis (EoE). […] Five major allergenic proteins from the egg of the domestic chicken (Gallus domesticus) have been identified that are responsible for IgE-mediated reactions; these are designated Gal d 1 to 5. Most of the allergenic hen’s egg proteins are found in egg white, including ovomucoid (Gal d 1), ovalbumin (Gal d 2), ovotransferrin (Gal d 3), lysozyme (Gal d 4), and ovomucin. Ovomucoid is the dominant allergen in egg (ie, is the allergen to which the most patients are sensitized), although ovalbumin is the most abundant protein comprising egg white.

Medical interventions, such as antihistamines, can help control symptoms while immunotherapy is a promising long-term treatment option. […] An egg allergy can lead to several complications, ranging from mild discomfort to severe health risks. These complications include anaphylaxis, increased susceptibility to other allergies, and allergic eczema. […] Preventing egg allergy largely revolves around avoiding exposure to eggs, particularly in those who are already known to be allergic.

  Egg allergy is an immune hypersensitivity to proteins found in chicken eggs, and possibly goose, duck, or turkey eggs. […] The cause is typically the eating of eggs or foods that contain eggs. Briefly, the immune system over-reacts to proteins found in eggs. This allergic reaction may be triggered by small amounts of egg, even egg incorporated into cooked foods, such as cake. People with an allergy to chicken eggs may also be reactive to goose, duck, or turkey eggs. […] Strong predictors for adult-persistence are anaphylaxis, high egg-specific serum immunoglobulin E (IgE), robust response to the skin prick test and absence of tolerance to egg-containing baked foods. […] Five major allergenic proteins from the egg of the domestic chicken (Gallus domesticus) have been identified; these are designated Gal d 1-5. Of these, ovomucoid is the dominant allergen, and one that is less likely to be outgrown as children get older.

However, unlike primary allergies in childhood, the allergen implicated in bird-egg syndrome is found in the egg yolk rather than the egg white. […] In terms of immunotherapy, which treats the causes of an allergy, there is no clear data available for egg allergies or food allergies in general. Recent studies from 2015 suggest that, in the case of peanut allergies, desensitisation may be possible. This involves giving the patient small amounts of the allergen and stimulating the immune system by building up to a larger amount of the trigger substance, which can then be tolerated by the end of the therapy. It is still unclear whether this therapy can be applied in the treatment of egg allergies in the future.

  https://www.ecarf.org/en/information-portal/allergies-overview/chicken-egg-allergy/

  Eggs are among the food allergens of animal origin and contain certain proteins that can trigger an immune response in susceptible people. The most common allergens are contained in the egg white, whereas it is much rarer for the egg yolk to trigger an allergy. […] The two main allergens are known as ovomucoid and ovalbumin. They are found in the egg white. Ovomucoid is acid resistant and heat stable. People who have an allergic reaction to ovomucoid usually cannot tolerate raw or cooked eggs. On the other hand, ovalbumin breaks down at high temperatures, so people who have an allergic reaction to ovalbumin can often tolerate cooked eggs. […] After milk allergies, egg allergies are the second most common allergic disease in childhood. They usually appear during the first two years of life.
