Objective: The aim: The objective of the study was to analyze the frequency of Arg16Gly polymorphism in the β2 -adrenoceptor (β2 -АR) gene in patients with bronchial asthma (BA) and to assess the association of the polymorphism with BA risk.
Patients And Methods: Materials and methods: We examined 553 BA patients and 95 apparently healthy individuals. Arg16Gly polymorphism in the β2 -АR gene (rs1042713) was determined using polymerase chain reaction-restriction fragment length polymorphism analysis.
