Using transcriptomics analyses in European MeDALL birth cohorts and RNA sequencing in Puerto Rican children, AR as a single disease was found to be associated with Toll‐like receptor gene expression (TLR ), whereas rhinitis associated with asthma was linked with IL‐5 and IL‐33, confirming that the two diseases are different [139 ]. The gene discussed is IL5; the disease is asthma.
