Instead, the presence of the minor allele T in the TLR7 rs179008 gene in males was associated with the RSV aetiology of bronchiolitis (100% vs. 70.4% in those with the major allele A) and with the need for feeding support (54.5% vs. 24.1%, respectively) (Table 4). This evidence concerns the gene TLR7 and bronchiolitis.
