目的:了解潮州地区新生儿的葡萄糖-6-磷酸脱氢酶(glucose-6-phosphate dehydrogenase deficiency,G6PD)缺乏症的发病率及基因突变特点。方法:采用荧光斑点法对2010至2012年潮州市中心医院出生的2 500例新生儿进行G6PD缺乏筛查。对初筛阳性的67例标本用高分辨熔解曲线分析技术(high-resolution melting,HRM)和PCR-DNA测序法进行基因分型。结果:本次筛查发现潮州地区新生儿人群的G6PD缺乏症总发生率为2.6%(67/2 500),其中男婴44例(3.22%,44/1 365),女婴23例(2.03%,23/1 135),男女检出率比为1.91∶1(44/23),两者之间无统计学差异( χ2=3.404,P=0.065)。67例初筛阳性标本中58例检测出有突变,9例未检出突变,共检出7种基因突变,含26例1 376 G>T(c.1466G>T,44.83%),22例1 388 G>A(c.1478G>A,37.94%),5例95 A>G(c.185A>G,8.62%),2例871 G>A(c.961G>A,3.45%),1例392 G>T(c.482G>T,1.72%),1例493 A>G(c.583A>G,1.72%),1例1360 C>T(c.1450C>T,1.72%),没有检出复合突变类型。结论:潮州地区具有较高的G6PD发生率。G6PD Canton(1376 G>T)、G6PD Kaiping(1388 G>A)和G6PD Gaohe(95 A>G)3种突变类型最常见。
Objective:To investigate the prevalence and genotypic mutant characteristics of the glucose-6-phosphate dehydrogenase deficiency(G6PD) deficiency in neonates of Chaozhou area. Methods:A total of 2 500 neonates born in Chaozhou Central Hospital were screened for G6PD deficiency by inflorescent spot test(FST). Then,all positive screening samples were subjected to genotype through high-resolution melting assay or DNA sequencing. Results:The prevalence of G6PD deficiency in Chaozhou was 2.6%(67/2 500). Of the 67 infants suspected to be G6PD deficiency based on FST,44(3.22%,44/1 365) were males and 23(2.03%,23/1 135)were females. The detected ratio of male and female was 1.91∶1 without statistical differences( χ2=3.404,P=0.065). Among these 67 positive screening samples based on FST,58 had gene mutation;7 kinds of mutation were found including 26 cases of 1376 G>T(c.1466G>T,44.83%),22 cases of 1 388 G>A(c.1478 G>A,37.94%),5 cases of 95 A>G(c.185A>G,8.62%),2 cases of 871 G>A(c.961G>A,3.45%),1 case of 392 G>T(c.482G>T,1.72%),1 case of 493 A>G(c.583A>G,1.72%) and 1 case of 1360 C>T(c.1450C>T,1.72%). Conclusion:The incidence of G6PD deficiency is high in Chaozhou area. More male infants are detected with G6PD defi-ciency than females. G6PD Canton(1376 G>T),G6PD Kaiping(1388 G>A) and G6PD Gaohe(95 A>G) are the three most common variants in this area.
