摘要/Abstract

摘要：

目的旨在探讨甲状腺结合球蛋白（TBG）缺乏症的临床特征和遗传学特点，提升临床诊断准确性，避免误诊及过度治疗。方法对来自3个不同家系的成员进行SERPINA7基因测序，探究其遗传基础。结果通过全外显子组测序检测出3个家系的变异均发生在外显子，分别为c.712A>G(p.M238V)、c.1114delC(p.L372Ffs*23)、c.383-401dup(p.F135Afs*21)，其中家系1、家系3的变异属首次报道。结论 TBG缺乏症无需特殊治疗，正确的诊断与全面的疾病教育是该病管理的关键。本研究发现了2个新的SERPINA7基因变异，拓展了该基因的变异谱。

Abstract:

Objective To investigate the clinical characteristics and genetic features of thyroid-binding globulin (TBG) deficiency, enhance the accuracy of clinical diagnosis, and avoid misdiagnosis and overtreatment. Methods Members from three different families were subjected to SERPINA7 gene sequencing to explore its genetic basis. Results The variants detected in the three families through whole-exome sequencing occurred in exons, specifically c.712A>G(p.M238V), c.1114delC(p.L372Ffs*23), and c.383-401dup(p.F135Afs*21), with the variants in Family 1 and Family 3 being reported for the first time. Conclusion TBG deficiency does not require special treatment; correct diagnosis and comprehensive disease education are key to the management of this condition. This study identified two new SERPINA7 gene variants, expanding the mutation spectrum of this gene.
