HLA-DQA1 and egg allergy: We should note that the HLA-DQA1*01:02 allele is not associated with baseline selection criteria of egg allergy and eczema (P = 4.82 × 10–1 and P = 2.76 × 10–1, respectively), and the association between psIgG4 and HLA-DQA1*01:02 is independent of these baseline selections (P = 9.49 × 10–5, adjusted for egg allergy and eczema).
