In the study by Fan et al, patients with mycoplasma pneumoniae pneumonia (MPP) were statistically different from healthy controls in the tilters of TIM1, and blocking TIM1 expression may reduce the risk of MPP‐induced damages in heart and liver.13 In recent years, many scholars have focused on the effects of TIM‐1 gene polymorphisms and diseases. Here, HAVCR1 is linked to Mycoplasma pneumoniae pneumonia.
