Relationship between IFN-γ+874 A/T site and IL-2-330 T/G site single nucleotide polymorphism with the susceptibility of recurrent aphthous ulcer / 实用口腔医学杂志

ABSTRACT

Objective:To explore the possible relationship between recurrent aphthous ulcer( RAU) and the single nucleotide polymor-phism(SNP)of IFN-γ+874A/T site and IL-2-330T/G site. Methods:138 RAU patients and the 124 health control subjects were in-cluded. IFN-γand IL-2 serum concentration were detected by ELISA. IFN-γ+874A/T site and IL-2-330T/G site of the whole blood were detected by RFLP-PCR and SSP-PCR. Results:IFN-γand IL-2 levels in serum of the patients were significantly lower than those of the controls(P0. 05). Conclusion: IFN-γ+874A/T site was associated with the risk of RAU. But,IL-2-330T/G site was not.
