In asthma, the expression of CPA3 was negatively associated with ICS daily dose (r = −.339; P = .011), IL1B expression was positively associated with bronchial lavage fluid (BLF) total cell count (r = .340; P = .013) and both CLC and POSTN expression were associated with lymphocytes percentage in BLF (r = −.355, P = .009; r = −.300, P = .025, respectively). This evidence concerns the gene CLC and asthma.
