Chen et al. [29] found the TKK/hMps1 gene by whole‐exome sequencing; studies on TTK/hMps1 have exclusively focused on its role in tumorigenesis, though the contribution of TTK/hMps1 to bronchiectasis, bacterial, mycobacterial, or fungal infections, and overall progression to pulmonary disease is currently unknown. Here, TTK is linked to bronchiectasis.
