Objective:
To study the association of single nucleotide polymorphisms (SNP) (rs2393903 and rs10995251) in ZNF365 gene with bronchial asthma and its clinical characteristics in Han Chinese children in Hubei, China.
Methods:
A total of 221 children with bronchial asthma and 243 normal children, all of whom were from Hubei, were recruited to carry out a case-control study. The genotype and allele frequencies of two SNPs in ZNF365 gene were determined using the polymerase chain reaction-restriction fragment length polymorphism technique.
Results:
There were no significant differences in the distribution of three genotypes (GG, GA, AA) and allele frequency in SNP rs2393903 between the asthma and control groups (P>0.05). However, there were significant differences in the distribution of three genotypes (CC, CT, TT) and allele frequency in SNP rs10995251 between the asthma and control groups (P<0.05); C allele was a risk factor (OR=1.380). The asthmatic children with CC genotype of SNP rs10995251 had a significantly higher serum level of total immunoglobulin E (IgE) than those with TT genotype (P<0.05).
Conclusions:
The SNP rs10995251 in ZNF365 gene is associated with the susceptibility to bronchial asthma in children in Hubei, China, and the SNP may affect the level of serum IgE in these children.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

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.
