The asthma-associated alleles, rs2270401-A and rs2302774-G, respectively, were both associated with decreased expression of ERBB2 after RV infection (Fig. 4A), consistent with results of a study in 155 asthma cases and controls reporting an inverse correlation between ERBB2 expression in ex vivo lower AECs and asthma severity [100]. Here, ERBB2 is linked to asthma.
