Idiopathic portal hypertension (IPH) is defined as the presence of portal hypertension in the absence of a common cause. IPH can have several etiologies, one of which is a genetic disorder. Some genetic mutations, such as KCNN3 and DGUOK, were shown to be related to IPH pathogenesis. This is the first case report of a 22-year-old man who was diagnosed with IPH with a novel heterozygous mutation in the histidine-rich glycoprotein gene (c.545G > C, p.R182T). Using bioinformatics analysis and the protein quantification method, we showed that this novel mutation has a pathogenetic role in IPH. Our study broadens the mutation spectrum of the histidine-rich glycoprotein gene and provides new ideas for IPH etiology.
特发性门静脉高压（IPH）被定义为在没有常见病因的情况下出现门静脉高压。IPH可有多种病因，其中之一是遗传疾病。一些基因突变，如KCNN3和DGUOK，已被证明与IPH发病机制有关。这是首例关于一名22岁男性的病例报告，该患者被诊断为IPH，其富含组氨酸糖蛋白基因存在一种新的杂合突变（c.545G>C，p.R182T）。通过生物信息学分析和蛋白质定量方法，我们表明这种新突变在IPH发病机制中起致病作用。我们的研究拓宽了富含组氨酸糖蛋白基因的突变谱，并为IPH病因提供了新的思路。
