Most studies (n = 8, 73%) captured offspring birth outcomes (e.g., admission to special care nursery, birth timing, birth weight, fetal death, fetal growth, length of hospital stay, PTB status) while two (18%) explored early-life outcomes (e.g., cord blood IgE levels, infant RSA) and one (9%) measured adolescent outcomes (e.g., asthma control, cytokine production). The gene discussed is IGHE; the disease is asthma.
