摘要: 目的 初步评估葡萄糖激酶(glucokinase,GCK)基因突变引起的青少年发病的成年型糖尿病2型(maturity onset diabetes of the young 2,MODY2)在妊娠期血糖异常人群中的比例,建立一种识别GCK基因突变的筛查方法。方法 回顾性分析2016年1月1日至2018年12月31日在首都医科大学附属北京潞河医院进行孕期检查的妊娠妇女,以孕早期、孕中期及孕后期空腹静脉血糖均≥5.5 mmol/L,血清三酰甘油至少1次≤1.43 mmol/L,妊娠24~28周75 g葡萄糖耐量试验2 h增量小于4.6 mmol/L为筛查条件,对受试者进行葡萄糖激酶基因序列测定。结果 共纳入2 454例受试者,符合GCK基因筛查条件者12例,获得外周血DNA标本5例,发现1例GCK基因突变者。结论 妊娠期间3次空腹静脉血糖均≥5.5 mmol/L且血清三酰甘油至少1次≤1.43 mmol/L且口服葡萄糖耐量试验2 h血糖增量< 4.6 mmol/L的方法,可以发现GCK基因突变,该类型糖尿病在妊娠期血糖异常人群中比较罕见。

Abstract: Objective To estimate the prevalence of maturity onset diabetes of the young 2 (MODY2) caused by glucokinase (GCK) gene mutation and to establish a clinical strategy for identifying GCK gene mutation in pregnancy woman. Methods A retrospective study was conducted on pregnant women undergoing pregnant examination at Luhe Hospital, Capital Medical University on January 1, 2016 and December 31, 2018.The GCK gene was sequenced in patients meeting the following criteria:fasting blood glucose(FBG) ≥ 5.5 mmol/L (at least 3 times) and triglyceride (TG) ≤ 1.43 mmol/L (at least once). The 2-hour increment of 75 g glucose tolerance test was less than 4.6 mmol/L in 24-28 weeks of gestation. Results A total of 2 454 subjects were screened of which 12 patients met the screening criteria. DNA samples of 5 patients were sequenced, with 1 patient with GCK mutation identified. Conclusion Our screening method based on FBG ≥ 5.5 mmol/L (at least 3 times), triglyceride ≤ 1.43 mmol/L(at least once) and oral glucose tolerance test(OGTT)2 h glucose increment < 4.6 mmol/L is feasible for screening GCK gene mutation in pregnant women. GCK mutation is not the main cause of abnormal gestational blood glucose in China.

Key words: abnormal blood glucose during pregnancy, maturity onset diabetes of the young 2, glucokinase-maturity onset diabetes the young
