This study reported on a 24-year-old woman who complained of a paroxysmal headache for six months and elevated blood pressure for four months. Laboratory examination revealed increased serum potassium and chloride levels, metabolic acidosis, suppressed renin activity, and increased plasma aldosterone concentration. Whole-exome sequencing revealed a heterozygous mutation in exon 11 of the KLHL3 gene: c.1298G > A. After treatment with low-dose hydrochlorothiazide, her clinical problems were controlled. This patient is the first case of Gordon syndrome (GS) within the Chinese population caused by a heterozygous KLHL3 mutation. A systematic review of the published literature identified 27 patients with GS caused by a KLHL3 mutation. These patients had a mean age of 28.2 ± 22.0 years; 74.1% presented with hypertension, 76.9% with hyperkalemia, and 59.1% with metabolic acidosis. The patients also had varying levels of plasma renin activity and plasma aldosterone concentrations.
本研究报告了一名24岁女性,她主诉阵发性头痛6个月,血压升高4个月。实验室检查显示血清钾和氯水平升高、代谢性酸中毒、肾素活性受抑制以及血浆醛固酮浓度升高。全外显子测序显示KLHL3基因第11外显子存在杂合突变:c.1298G>A。经小剂量氢氯噻嗪治疗后,她的临床问题得到控制。该患者是中国人群中首例由杂合KLHL3突变引起的戈登综合征(GS)病例。对已发表文献的系统综述确定了27例由KLHL3突变引起的GS患者。这些患者的平均年龄为28.2±22.0岁;74.1%表现为高血压,76.9%表现为高钾血症,59.1%表现为代谢性酸中毒。这些患者的血浆肾素活性和血浆醛固酮浓度也各不相同。
