MECP2

基因产物：甲基化CpG结合蛋白-2。

蛋白功能：在神经元中表达较高，可与甲基化的DNA序列特异性结合影响一些基因的转录，在神经系统成熟过程中发挥重要作用[102]。

相关疾病：新生儿重度脑病（XLR）[1]；X连锁遗传性精神发育迟滞综合症（XLR）[2]；Rett综合症（XLD）(部分可表现为非进行性疾病中的肌阵挛脑病、Lennox-Gastaut 综合征、癫痫性脑病伴慢波睡眠期持续棘慢波)[3-5]；自闭症（易感基因）（XL）[6]。

突变数据库：ClinVar数据库。

相关临床研究：PubMed数据库（PMID: 27988477(Epilepsy Behav. 2017)）
