dc.description.abstract | Background— Atopy and plasma IgE concentration are genetically complex traits, and the specific genetic risk factors that lead to IgE dysregulation and clinical atopy are an area of active investigation.
Objective— To ascertain the genetic risk factors which lead to IgE dysregulation.
Methods— A genome wide association study (GWAS) was performed in 6,819 participants from the Framingham Heart Study (FHS). Seventy of the top SNPs were selected based on p-values and linkage disequilibrium among neighboring SNPs and evaluated in a meta-analysis with five independent populations from the KORA, B58C, and CAMP cohorts.
Results—
Thirteen SNPs located in the region of three genes, FCER1A, STAT6, and IL-13, were found to have genome-wide significance in the FHS GWAS. The most significant SNPs from the three regions were rs2251746 (FCER1A, p-value 2.11×10 -12), rs1059513 (STAT6, p-value 2.87×10 -08), and rs1295686 (IL-13, p-value 3.55×10 -08). Four additional gene regions - HLA-G, HLA-DQA2, HLA-A, and DARC - reached genome-wide statistical significance in meta-analysiscombining FHS and replication cohorts, although the DARC association did not appear independent of SNPs in the nearby FCER1A gene.
Conclusion— This GWAS of the FHS has identified genetic loci in HLA genes that may have a role in the pathogenesis of IgE dysregulation and atopy. It also confirmed the association of
known susceptibility loci, FCER1A, STAT6, and IL-13, for the dysregulation of total IgE. | en_US |
