We found strong associations between childhood asthma and variants near gasdermin B (GSDMB) and zona pellucida‐binding protein 2 (ZPBP2) on chromosome 17q21.1 (e.g., rs4795399‐T, odds ratio = 1.43, p value = 1.61E−23), which is consistent with previous studies (Moffatt et al. 2010; Pividori et al. 2019; Verlaan et al. 2009) (Table S4 and Figure S3, Supporting Information File 1). Here, ZPBP2 is linked to asthma.
