摘要:

目的分析莆田地区新生儿葡萄糖‐6‐磷酸脱氢酶(glucose‐6‐phosphate dehydrogenase,G‐6‐PD)缺乏症基因型与酶活性亚型的分布特征。方法收集2020年7月—2021年6月新生儿G‐6‐PD缺乏症筛查阳性病例215例,采用速率法检测酶活性,异常168例;145例酶活性异常病例采用多色熔解曲线分析法检测突变基因;分析基因型及酶活性亚型的分布情况。结果129例G‐6‐PD缺乏症突变基因分布:c.1376G > T 39例,c.1024C > T 24例,c.1388G > A 22例,c.95A > G 13例,c.392G > T 11例,c.487G > A 9例,c.871G > A 5例,c.1360C > T 3例,c.592C > T 1例,c.517T > C 1例,混合突变(c.1024C > T/c.392G > T)1例。酶活性亚型分布:Ⅰ级0例,Ⅱ级95例,Ⅲ级73例,Ⅳ级0例,Ⅴ级0例。结论莆田地区共检出10种G‐6‐PD缺乏症常见突变基因型和1种混合突变;前3顺位突变类型为:c.1376G > T,c.1024C > T,c.1388G > A;本地区酶活性亚型以Ⅱ级和Ⅲ级为主。

Abstract:

ObjectiveTo analyze the distribution of genotype and enzyme activity subtypes of Glucose-6-Phosphate Dehydrogenase deficiency in Putian region.MethodsWe collected 215 newborn screening cases positive for G-6-PD deficiency from July 2020-June 2021, and enzymatic activity was detected by rate method and was abnormal in 168 cases; Mutant genotypes were detected by Multicolor Melting Curve Analysis in 145 cases with abnormal enzyme activity; The distribution of genotypes and enzyme activity subtypes were analyzed.ResultsDistribution of mutation sites in 129 G-6-PD deficiency cases: c.1376G > T in 39 cases, c.1024C > T in 24 cases, c.1388G > A in 22 cases, c.95A > G in 13 cases, c.392G > T in 11 cases, c. 487G > A in 9 cases, c. 871G > A in 5 cases, c.1360C > T in 3 cases, 1 case of mixed mutation (c.1024C > T/c.392G > T),c.592C > T in 1case, c.517T > C 1case; Distribution of the enzyme-active subtypes: Ⅰ Level 0 case, Ⅱ Level 95 cases,Ⅲ Level 73cases,Ⅳ Level 0case,and Ⅴ Level 0 case.ConclusionA total of 10 common mutant genotypes and one mixed mutation were detected in Putian region; The top three common mutation types were c.1376G > T, c.1024C > T and c.1388G > A;The enzyme active subtypes in this region are mainly of Level Ⅱand Ⅲ.
