Rett syndrome is a severe neurodevelopmental disease caused by mutations in the X-linked gene encoding for the methyl-CpG-binding protein MeCP2. Here, we report the identification of FOXG1-truncating mutations in two patients affected by the congenital variant of Rett syndrome. FOXG1 encodes a brain-specific transcriptional repressor that is essential for early development of the telencephalon. Molecular analysis revealed that Foxg1 might also share common molecular mechanisms with MeCP2 during neuronal development, exhibiting partially overlapping expression domain in postnatal cortex and neuronal subnuclear localization.
瑞特综合征是一种严重的神经发育疾病,由编码甲基-CpG结合蛋白MeCP2的X连锁基因突变引起。在此,我们报告了在两名患有先天性瑞特综合征变体的患者中鉴定出FOXG1截短突变。FOXG1编码一种脑特异性转录抑制因子,对端脑的早期发育至关重要。分子分析表明,Foxg1在神经元发育过程中可能也与MeCP2共享共同的分子机制,在出生后皮质和神经元亚核定位中表现出部分重叠的表达域。
