Outline of Final Research Achievements

The aim of this study was to elucidate the genetic and environmental factors associated with allergic diseases/intermediate phenotypes such as specific IgE production. We performed genotyping on samples of an birth cohort study using SNP arrays with approximately 660,000 genetic markers per person.
We confirmed association between specific IgE production against Cry j 1 and HLA-DPB1*02 allele at 5 years old (P=0.00089, OR=0.61). We also found associations between several HLA alleles and specific IgE production against allergen components at 9 years old (P < 1×10-6).

Academic Significance and Societal Importance of the Research Achievements

喘息、アトピー性皮膚炎、花粉症、食物アレルギー等のアレルギー疾患は、近年我が国において全人口の約2分の1が罹患していることが明らかとなっている。このような社会的に大きな負担となっているアレルギー疾患の予防・治療のためには「遺伝・環境要因の相互作用」を検討する研究が不可欠である。本研究ではアレルギー疾患発症の前段階であるアレルゲン特異的IgE抗体産生に関与すると考えられるHLAアレルを複数検出しており、今後、発症予測法の開発につながることが期待される。
