【Abstract】 Objective To identify the distribution feature of β 2-ARGln27Glu gene in the Hans in Guangdong Province. Methods β 2-ARGln27Glu genes from normal individuals were amplified with PCR. Results It was shown that the gene frequency of β 2-AR Gln27Glu was as followed;genotypefrequency:Gln/Gln 36.88%,Gln/Glu 52.46%,Glu/Glu 10.66%. Conclusions β 2-AR Gln27Glu gene s distribution in the Hans in Guangdong Province is different from those in other areas.更多还原
