摘要:

果糖-1,6-二磷酸酶缺乏症(fructose-1,6-bisphosphatase deficiency,FBP1D)是一种罕见的遗传性糖异生障碍性疾病,若未得到及时有效的治疗,可能导致严重的神经系统后遗症。本研究通过家系外显子组测序(trio-whole exome sequencing,trio-WES)确诊了1例FBP1D患者,该患者携带的NM_000507.4(FBP1) c.977T>C变异在我国尚未见报道。此外,对31例中国FBP1D患者的基因型和表型特征进行了总结与分析发现,其典型临床表现包括低血糖、代谢性酸中毒、胃肠道症状及意识障碍,感染是最常见的发病诱因。基因分析显示,FBP1基因c.960dup变异是我国患者中最常见的突变类型。提高临床医生对FBP1D的认识有助于实现对该病的早期诊断和积极干预,从而显著改善患者预后。

Abstract:

Fructose-1,6-bisphosphatase deficiency (FBP1D), a rare inherited metabolic disorder, may lead to severe neurological sequelae if not treated promptly and effectively. We report a case of FBP1D diagnosed through trio-whole exome sequencing (trio-WES). The NM_000507.4(FBP1) c.977T>C variant in this patient has not been reported in China. We summarized and analyzed the genotypic and phenotypic characteristics of 31 Chinese FBP1D patients from literature. The typical clinical manifestations included hypoglycemia, metabolic acidosis, gastrointestinal symptoms, and impaired consciousness, with the infection being the most common triggering factor. Genetic analysis revealed that the c.960dup variant in the FBP1 gene is the most prevalent variant among Chinese patients. Enhancing clinicians′ awareness of FBP1D can facilitate early diagnosis and active intervention, thereby significantly improve patient prognosis.
