Neurology:齐鲁医院:线粒体ND3突变引起的迁移性罗兰德脑病1例

2021-10-30 Naomii MedSci原创

Rolandic 癫痫 (RE) 或伴有中心颞部棘波 (BECT) 的儿童良性癫痫是最常见的儿童特发性部分癫痫综合征。 m.10191T>C突变可能出现在迁移性罗兰德脑病。

      Rolandic 癫痫 (RE) 或伴有中心颞部棘波 (BECT) 的儿童良性癫痫是最常见的儿童特发性部分癫痫综合征,其中“特发性”意味着遗传倾向。尽管长期以来人们认为 RE 具有遗传成分,但临床和遗传研究显示出复杂的遗传模式。此外,最近关于双胞胎研究的报告挑战了 RE 中潜在的主要遗传影响。同时,许多基因或基因座已被证明与 RE/非典型 RE (ARE) 谱相关,在 ARE 中具有更高频率的致病变异。然而,对 RE 谱中更常见形式的遗传基础的全面了解仍然难以捉摸。近日,来自山东大学齐鲁医院的研究人员报道了一则发生了m.10191T>C突变的RE病例:

 

      一名18岁的女性因局灶性癫痫而入院治疗。经系列MRI检查显示为迁移性罗兰病变(图A-D),当病变出现时,脑电图显示尖锐的波形。最初的鉴别诊断包括脑静脉血栓形成、MOGAD和代谢紊乱。MRV、血清和脑脊液分析均未发现。NGS对尿沉渣mtDNA的分析显示,mt-ND3基因存在致病性m.10191T>C突变(突变载量为87%)。进一步分析发现m.10191T>C变异在血液(24%)和口腔粘膜(86%)细胞中是异质性的。这个案例说明m.10191T>C突变可能出现在迁移性罗兰德脑病。

患者1年前首次神经学检查时的FLAIR图像(A),2个月后左侧罗兰迪克皮质的微小病变消失(B),9个月后再次出现(C)。随后,右侧罗兰迪克皮质又出现了类似的微小病变(D)。

(A)患者1年前做的FLAIR头部影像检查

(B)2个月后位于左侧Rolandic皮层的微小损伤消失,并在9个月后再次出现(C)

(D)随后发生在右侧Rolandic皮层的相似微小损伤
