Purpose:
Recently, the roles of TIM-1 genetic polymorphisms in asthma have been extensively studied, with conflicting results. Therefore, we performed the present meta-analysis to better assess potential associations of TIM-1 genetic polymorphisms with asthma.
Methods:
Eligible articles were searched in PubMed, Medline, EMBASE, Google Scholar, and CNKI up to December 2016. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to detect any potential associations between TIM-1 genetic polymorphisms and asthma.
Results:
A total of 12 articles including 3120 asthma patients and 2825 control subjects were analyzed. The overall and subgroup analyses revealed that TIM-1-416G>C single nucleotide polymorphism was significantly associated with asthma for the Asian population in the codominant (G/G vs. G/C, p = 0.0003, OR 1.86, 95% CI 1.33-2.60) and dominant (G/G vs. G/C + C/C, p < 0.0001, OR 1.94, 95% CI 1.40-2.69) genetic models. Nevertheless, we failed to detect any significant associations between TIM-1-416G>C single nucleotide polymorphism and asthma in Caucasians. Additionally, according to our analyses, TIM-1 5383_5397 insertion/deletion polymorphism was not correlated with asthma in both Asians and Caucasians.
Conclusions:
In conclusion, our findings suggest that TIM-1-416G>C single nucleotide polymorphism is associated with asthma susceptibility for the Asian ethnicity in certain genetic models. However, TIM-1 5383_5397 insertion/deletion polymorphism may not be correlated with the risk of asthma.

Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma-I: Introduction
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
