  • 神经元移行障碍发病机制研究进展

    胚胎发育时期因各种因素引起的神经元移行障碍,常导致大脑皮质发育畸形(Malformation of cortical development,MCD),也是引起患儿发育迟缓和癫痫的常见原因。快速发展的分子生物学、影像学和基因遗传学丰富了大脑皮质发育的相关知识,畸形的报道不仅在数量和种类上有所增长,同时相关研究已经确定了几个基因,可能破坏神经细胞增殖、移行以及晚期皮层组织形成的每一个重要阶段。不同的MCD在临床表现上也有很大的表型异质性,现就MCD的发生机制、易感基因进行阐述,为MCD后期研究提供参考依据。

  • Analysis of genotypes and clinical phenotypes in two children with convulsions as the first symptom of hypoglycemia

    ObjectiveTo recognize the convulsion caused by hypoglycemia, and to analyze its genotype and clinical phenotype, so as to deepen the understanding of hyperinsulinemia.MethodFull exon detection were performed on 2 children with hypoglycemia and convulsions, who had been treated with antiepileptic drugs for 1 year in pediatric neurology department, Henan Provincial People’s Hospital in 2012 and 2014 respectively, but with poor curative effect.ResultABCC8 gene mutations were found in a child. The mutations located in Chromosome 11, with the nucleic acid changes of c.4607C>T (exon38) and the amino acid change of p.A1536V, rs745918247. The inheritancemode of ABCC8 gene could be autosomal dominant or autosomal recessive inheritance. Both of the parents were wild type on this genelocus. The gene mutation is associated with type 1 familial hyperinsulinemic hypoglycemia/nesidioblastosis. The other child was carrying GLUD1 gene mutation, witch is located in chromosome 10, with the nucleic acid changes of c.1498G>A (exon12) and the amino acid change of p.A500T. The inheritance mode of GLUD1 gene is autosomal dominant andthe child’s parents were both wild type. This gene mutationis associated with type 6 familial hyperinsulinemic hypoglycemia/nesidioblastosis. The 2 mutations have not been reported, which are new mutations.ConclusionMutations in these 2 gene loci may be the underlying cause of hypoglycemic convulsions, and are the best explanation for the poor convulsionscontrol of antiepileptic drugs.
