ABSTRACT
<p><b>OBJECTIVE</b>To study the association between the single nucleotide polymorphisms (SNP) of interleukin (IL)-19 and susceptibility to hepatitis B virus (HBV) infection in children.</p><p><b>METHODS</b>A case-control study was performed, and 136 children with positive HBsAg(case group) and 297 healthy children with negative HBsAg(control group) were enrolled. PCR and DNA sequencing were used for genotyping.</p><p><b>RESULTS</b>There were significant differences in the frequencies of genotypes of IL-19 rs1798 between the case and control groups. The case group also had a significantly higher proportion of children with CG genotype than the control group (p<0.05). There were significant differences in the frequencies of genotypes and alleles of IL-19 rs2243191 between the HBV infection and non-infection groups among children who born to HBV-positive mothers. The infection group had significantly higher proportions of children with TC and CC genotypes and C allele than the non-infection group (p<0.05).</p><p><b>CONCLUSIONS</b>The SNP of IL-19 rs1798 may be associated with susceptibility to hepatitis B in children, and the SNP of IL-19 rs2243191 may be associated with susceptibility to breakthrough HBV infection in children at a high risk of HBV infection.</p>
