We found that: In the Han children, except for FCER1B rs569108, the SNP sites of the other three genes have significant differences between the asthma group and the control group, but in the Kazakh children, the distribution of different genotype frequencies and risk allele frequencies of the SNP sites of these four genes in the asthma group and the control group has no statistical difference. Here, MS4A2 is linked to asthma.
