Title: Biomarker composition for predicting prognosis of food allergy with atopic dermatitis, and use thereof
Inventor: HONG SOO JONG
IPC: C12Q1/6883
Filed: 2021-06-09
Abstract: The present invention relates to a biomarker composition for predicting the prognosis of atopic dermatitis and a method for predicting the prognosis of atopic dermatitis, asthma, and rhinitis using the composition. More specifically, it is confirmed that there is a higher incidence of asthma and rhinitis in a persistent food allergy (FA) group accompanied by atopic dermatitis (AD) than in a non-allergic group, non-IgE-mediated atopic dermatitis group, and IgE-mediated atopic dermatitis group. As a result of checking genes which show expression differences in the stool of infants of six months or younger in each group, changes in the expression of AXIN1, CCND1, FZD2, and WNT6 are confirmed. Specifically, since the food allergy group accompanied by atopic dermatitis is distinguished from the remaining three groups by the expression levels of CCND1 and FZD2, a composition containing genes of which changes in the expression levels are confirmed is intended to be provided as a biomarker for predicting the progression of asthma and rhinitis in a patient with food allergies accompanied by atopic dermatitis in the future.
