ABSTRACT
Objective To study different groups of deficiency rate of glucose-6-phosphate dehydrogenase (G6PD)and enzyme activity assay in the detection rate of female heterozygote in the Southeast Dongguan.Methods From January 2007 to April 2013,of 39 475 cases of test results were collected in Tangxia Hospital of Dongguan city,the gene frequency and the detec-tion rate of female heterozygote could be calculated through genetic equilibrium law in different group.Results The male de-ficiency rates of G6PD in different group were Adult group(A)5.03%,Neonatal Group(B)5.10% and Total group(C) 5.06%,respectively,and there were no significant difference between each groups (χ2 =0.0404,P =0.980).The detection rate of female heterozygote of A,B and C in each groups were 27.13%,14.49% and 23.87%,respectively,and the differ-ence were statistically significant between different groups (χ2 =32.26,P =0.000).Conclusion Prevalence of G6PD defi-ciency in this area was 5.06% and there were differences between the deficiency rate of G6PD in different populations.The enzyme activity assay in female heterozygote detection rate is not satisfactory,especially in group B,which is conducive to ge-netic counseling,prenatal diagnosis and birth defects,such as providing more comprehensive information.
