OBJECTIVE: Ficolins are complement activating peptides that play a role in the initial host defense against infectious pathogens. In the present study, we investigated the relationship between single nucleotide polymorphisms (SNPs) in the ficolin 2 gene (FCN2) and chronic adenotonsillitis in pediatric cases.
STUDY DESIGN: Case-control study.
METHODS: A total of 101 pediatric patients diagnosed with chronic adenotonsillitis and 100 healthy children were enrolled in the study. Genotypes of FCN2 promoter SNPs - 602 G>A and -4 A>G, and the exonic SNP c.772G>T were determined by light SNP assay after realtime PCR analysis using genomic DNA samples obtained from peripheral blood samples of all participants.
RESULTS: Of the 101 chronic tonsillitis patients, 38 were girls and 63 were boys; the mean age was 5.2 ± 2.3 years. The c.772G>T SNP frequency was significantly higher in chronic adenotonsillitis cases compared to the control group (p = 0.00); however, no significant difference was determined at positions -602 G>A or -4 A>G (p > 0.05).
CONCLUSIONS: The FCN2 c.772G>T genotype appears to be associated with predisposition to chronic adenotonsillitis in the pediatric age group. This nucleotide change is likely to influence the level of gene expression and contribute to the development of disease.
