Interleukin-2 and Interleukin-8 Gene Polymorphisms and Acquired Aplastic Anemia Risk in a Chinese Population
Background/Aims:
Cytokines IL-2 and IL-8 both participate in immune regulation. However, the relationship between polymorphisms in these two cytokines and the risk of acquired aplastic anemia (acquired AA) has not been explored.
Methods:
We selected five SNPs including rs11575812, rs2069772 and rs2069762 of IL-2, rs2227306 and rs2227543 of IL-8. SNaPshot genotyping was used to test the genotypes of IL-2 and IL-8 polymorphisms in a population of 101 acquired AA patients and 165 healthy controls.
Results:
The rs2069762 G allele appeared to be a protective mutation, but no significant differences were found in other four SNPs. We also found that rs2069762 had an impact on the transcriptional regulation.
Conclusions:
It could be assumed that the rs2069762 polymorphism might reduce the risk of acquired aplastic anemia, while the remaining four SNPs might not contribute to susceptibility to acquired AA in a Chinese population.
