Southern Chinese Han Asthma Crowd Ige High Affinity Receptor Beta Chain Gene E237g Mutation And Comparative Study Of Healthy People

Objecti\"ef To ana1yze the assoc1at 1on between Fc s RI-- Dgene E237G variant and asthma in the peoD1e of the Haflnat iona1 itv of south china.Methods' Amp1 1 fi cat iofl refractory mutat ion system PCR(:AR)IS--PCR) was used to determine Fc E RI-- D gene E237Gvariallt 1n 69 unre1ated pat 1 ents wi th asthma and 28 hea1 thycoritro1s frOm the peoD1e of the Han nationa1 f1ty of sotlth{h i na.ResLlltsf E2;37(i was detected in 8 subjects l'rom 69d.thlnat ics (l l. 6%), afld l in 28 hea1t[1y contro1s (3. d796).The TreqLlenc }- of genot ype E237G 1oc i i n asthfl1at i c s' G1 u/'G l }rgent)t Vpe accotlnt s tor 7. 2o9b, G1 y/'G1y genotype t:1. 3d9b andGl u (j1u 88.
