Tizaoui et al 30 studied a total of eight previous case‐control studies and showed a significant association between homozygous wild type of rs1544410 with risk of asthma (OR = 2.017, 95% CI = 1.236‐3.851, P = .017), although it seems that the VDR rs2228570 is not a probable risk factor for development of asthma in the codominant model (OR = 1.187, 95% CI = 0.975‐1.446, P = .088). Here, VDR is linked to asthma.
