Abstract:

Objective To investigate the correlations between interleukin 13(IL-13),activation-induced cytidine deaminase(AICDA) and thymic stromal lymphopoietin(TSLP) gene loci and immunoglobulin E(IgE) in cord blood. Methods Cord blood samples were collected from 779 neonates. Genomic DNA was extracted from cord blood samples,and polymerase chain reaction-ligase detection reaction(PCR-LDR) was used to detect IL-13 gene loci(rs20541,rs1800925,rs848,rs1295686 and rs2069743),AICDA gene loci(rs2518144,rs17792729,rs2580873,rs2028373 and rs7304723) and TSLP gene loci(rs3806933,rs1545169,rs764917,rs1837253,rs2289276 and rs11466749). Cord blood IgE level was determined. Results There were correlations between IL-13 gene locus rs1295686(β=0.087,P=0.02),AICDA gene locus rs2028373(β=-0.082,P=0.02),TSLP gene loci rs2289276,rs764917 and rs1837253(β=-0.126,-0.083 and 0.188,P=0.01,0.03 and 0.00,respectively) and cord blood IgE. Conclusions IL-13 gene locus rs1295686,AICDA gene locus rs2028373 and TSLP gene loci rs2289276,rs764917 and rs1837253 may be allergy susceptible loci.
