ROBO2 and asthma: No associations were found at genome-wide significance level (p-value ≤ 5 × 10−8), but the SNP rs1166980 located in the ROBO2 gene was found to be suggestively (p-value ≤ 5 × 10−6) associated with ICS responsiveness in asthma patients (odds ratio (OR) for G allele: 7.01, 95% confidence interval (CI): 3.29–14.93, p = 4.61 × 10−7) (Figure 1 and Figure 2).
