At both measurement points, the majority of children and adolescents with current asthma and available IgE value was identified as atopic (10‐year follow‐up: 116, 77.3%; 15‐year follow‐up: 135, 81.8%), while non‐atopic asthma was comparatively less common (10‐year follow‐up: 34, 22.7%; 15‐year follow‐up: 30, 18.2%). This evidence concerns the gene IGHE and asthma.
