Background: The role of genetics in the etiology of peanut allergy is unknown. For complex
genetic traits, twin studies can provide information on the relative contribution of genetic
factors to a disease, as the relative confounding effects of environmental factors are
markedly decreased. Objective: This study was performed to search for evidence that
genetic factors influence peanut allergy by comparing the concordance rate for this allergy
among monozygotic and dizygotic twins. Methods: Twin pairs with at least one member with …
