Abstract Elucidating the functions of a particular gene is paramount to the understanding of how its dysfunction contributes to disease. This is especially important when the gene is implicated in multiple different disorders. One such gene is methyl-CpG-binding protein 2 (MECP2), which has been most prominently associated with the neurodevelopmental disorder Rett syndrome, as well as major neuropsychiatric disorders such as autism and schizophrenia. Being initially identified as a transcriptional regulator that modulates gene expression and subsequently also shown to be involved in other molecular events, dysfunc...

We report 2 cases of girls withMECP2 gene variants who do not have typical clinical features of Rett syndrome except for intellectual disability and seizures. Both patients present with adipositas, macrocephalia, precocious puberty, and seizures. They have prominent eyebrows and a short neck as well as short and plump fingers. Sequencing by NGS revealed a novel variant c.1162_1172del; p.Pro388* in both patients.Mol Syndromol

Patients with Rett syndrome (RTT) have severe mental and physical disabilities. The majority of RTT patients carry a heterozygous mutation in methyl-CpG binding protein 2 (MECP2), a X-linked gene encoding an epigenetic factor crucial for normal nerve cell function. No curative therapy for RTT syndrome exists and cellular mechanisms are incompletely understood. Here, we developed a CRISPR/Cas9-mediated system that targets and corrects the disease relevant regions of the MECP2 exon 4 coding sequence. We achieved homologous recombination (HR) efficiencies of 20-30% in human cell lines and iPSCs. Furthermore, we successfully i...

Sebastião, Maria J. Diógenes, Eleonora Aronica, Eleonora PalmaAbstractThe investigation on neurotransmission function during normal and pathologic development is a pivotal component needed to understand the basic mechanisms underlying neurodevelopmental pathologies. To study these diseases, many animal models have been generated which allowed to face the limited availability of human tissues and, as a consequence, the most o...

Kaufmann, Michael Gill, Paolo Guasoni, Daniela TropeaAbstractRett Syndrome (RTT) is a neurological disorder mainly associated with mutations in the X-linked gene coding for the methyl-CpG binding protein 2 (MECP2). To assist in studying MECP2's function, researchers have generated Mecp2 mouse mutants showing that MECP2's product (MeCP2) mostly function as a transcriptional regulator. During the last two decades, these models have been used to determine the genes that are regulated by MeCP2, slowly dissecting the aetiolo...
