Abstract

BACKGROUND AND OBJECTIVE

variants have been reported in a few cases of patients with hemiplegic migraine. To clarify the role of in familial hemiplegic migraine, we studied this gene in a large cohort of affected probands.

METHODS

was analyzed in 860 probands with hemiplegic migraine, and variations were identified in 30 probands. Genotyping of relatives identified a total of 49 persons with variations whose clinical manifestations were detailed.

RESULTS

variations were found in 12 of 163 probands who previously tested negative for , , and variations and in 18 of 697 consecutive probands screened simultaneously on the 4 genes. In this second group, pathogenic variants were found in 105 individuals, mostly in (42%), followed by (26%), 17%), and (15%). The variations included 7 distinct variants, 5 of which have already been described in persons with paroxysmal kinesigenic dyskinesia and 2 new variants. Eight probands had a deletion of the whole gene. Among the 49 patients with variations in , 26 had pure hemiplegic migraine and 16 had hemiplegic migraine associated with another manifestation: epilepsy (8), learning disabilities (5), hypersomnia (4), or abnormal movement (3). Three patients had epilepsy without migraine: 2 had paroxysmal kinesigenic dyskinesia without migraine, and 1 was asymptomatic.

DISCUSSION

should be regarded as the fourth autosomal dominant gene for hemiplegic migraine and screened in any affected patient, together with the 3 other main genes. Further studies are needed to understand how the same loss-of-function variations can lead to a wide range of neurologic phenotypes, including paroxysmal movement disorder, epilepsy, learning disabilities, sleep disorder, and hemiplegic migraine.

摘要

背景与目的

已有少数偏瘫型偏头痛患者的病例报道存在 变异。为了阐明 在家族性偏瘫型偏头痛中的作用,我们对一大组受累先证者进行了该基因研究。

方法

在 860 名偏瘫型偏头痛先证者中分析了 ,在 30 名先证者中发现了 变异。对亲属的基因分型共确定了 49 名具有变异的人,详细描述了他们的临床表现。

结果

在先前对 、 、 变异检测为阴性的 163 名先证者中的 12 名和同时对 4 个基因进行筛查的 697 名连续先证者中的 18 名中发现了 变异。在第二组中,在 105 名个体中发现了致病性变异,主要是在 (42%),其次是 (26%)、 (17%)和 (15%)。 变异包括 7 种不同的变异,其中 5 种已经在阵发性运动诱发性运动障碍患者中描述,还有 2 种新的变异。8 名先证者存在 基因的全部缺失。在 变异的 49 名患者中,26 名患有单纯性偏瘫型偏头痛,16 名患有偏瘫型偏头痛伴另一种表现:癫痫(8 名)、学习障碍(5 名)、嗜睡(4 名)或异常运动(3 名)。3 名患有无偏头痛的癫痫患者:2 名患有无偏头痛的阵发性运动诱发性运动障碍,1 名无症状。

讨论

应将 视为第四种常染色体显性遗传的偏瘫型偏头痛基因,并与其他 3 个主要基因一起筛查任何受累患者。需要进一步研究以了解相同的功能丧失 变异如何导致广泛的神经表型,包括阵发性运动障碍、癫痫、学习障碍、睡眠障碍和偏瘫型偏头痛。
