A family history of an allergic condition is a well-accepted risk factor for the development of an allergic condition in an individual, particularly for allergic disorders such as asthma, eczema, and allergic rhinitis. However, the question of whether specific allergen sensitization is inherited requires a complicated answer, as environmental exposure plays an important role in the development of allergen-specific IgE. This article summarizes the findings of recent studies in the literature regarding what is known about the inheritance of specific allergens. Overall, properly collected and analyzed data appear to both support and refute the hypothesis that specific allergen sensitization is inherited, even when attempting to account for the complexities of varying study methodologies and the evaluation of diverse populations and communities.
