摘要:

2例患者均幼年起病,主要临床表现为视觉障碍(如视觉闪光点)、偏侧肢体无力、麻木,症状持续约30 min后出现单侧搏动性头痛伴有恶心、呕吐,以上症状在休息后可缓解,不伴其他神经系统疾病。神经系统查体、头颅CT、磁共振成像、脑电图检查和遗传代谢疾病筛查均未见异常。根据《国际头痛疾病分类(第三版)》诊断标准,2例患者符合典型单纯偏瘫型偏头痛的诊断。ATP1A2基因检测显示,2例患者均存在ATP1A2基因突变。病例1为杂合突变c.G2284A/p.G762S,该突变此前报道为致病性突变;病例2为杂合突变c.C3022T/p.R1008W,查阅既往文献及数据库未见该位点单独致病的相关报道。根据美国医学遗传学和基因组学会指南,病例1的ATP1A2基因杂合突变c.G2284A/p.G762S评定为“可能致病”,病例2的ATP1A2基因杂合突变c.C3022T/p.R1008W评定为“意义不明确”。

Abstract:

Both 2 cases developed hemiplegic migraine at an early age. The clinical manifestations were almost the same, featuring visual disturbance (such as visual flash) and hemiplegia or hemiparesis. A unilateral pulsating headache with nausea and vomiting developed soon after these auras which lasted about half an hour. The headache was relieved after rest. No abnormality was found in the neurological examination, cranial CT, MRI, electroencephalogram and metabolic disease examination. According to The International Classification of Headache Disorders, 3rd edition (ICHD-3) , both 2 cases were presented as typical pure hemiplegic migraine without other neurological disorders. Genetic sequencing showed ATP1A2 gene mutation in the 2 patients. Heterozygous mutation c.G2284A/p.G762S was present in case 1 and it has previously been shown to be a pathogenic mutation. Case 2 was identified with c.C3022T/p.R1008W, and no related reports were found in the previous literature and databases. According to the standard of American College of Medical Genetics and Genomics (ACMG), c.G2284A/p.G762S in case 1 was as "likely pathogenic" and c.C3022T/p.R1008W in case 2 was as "uncertain significance".
