This contributes to the variety of RTT phenotype and symptom severity. This complex molecular network interaction leads to effects in cellular morphology e. But as MECP2 basic function is global transcription dampener in combination with activity dependent activation of transcription this suggests that reduced membrane material production is a consequence of lack of activity specific transcription activation. In MECP2 null mouse model reduced neuronal differentiation [ ] and synaptic deficits [ 98 ] were observed. JIMD Rep. MECP2 binding to these sites prevents them from being converted. Increased dendritic complexity and axonal length in cultured mouse cortical neurons overexpressing methyl-CpG-binding protein MeCP2. Genes Brain Behav.

    Mosaic expression with only wild-type MECP2 active in females are possible but supposed to be extremely rare [ 24 ].

    This pathway driven approach may serve as a use case for other rare diseases, too. These are not likely to be able to cure RTT itself but may help to reduce the severity of specific symptoms. MECP2 was generally considered as a transcription inhibitor but recent research found also a conditional transcription activation function.

    The results confirm that NMD is at least partially involved.

    This receptor links post and presynaptic compartments and influences not only synapsis function but also neuronal differentiation [ 83 ].

    MECP2 is located on the X chromosome X— on the reverse strand ensembl, human genome built 8. Still, it remains unclear whether this is the cause or just one of the consequences of reduced neuronal cell size and network connectivity of RTT.

    They created and compared expression profiles of two iPSCs cell lines derived from each of the patients, one with the X chromosome active that has the wild type MECP2 and the other one with the chromosome with the mutated gene.

    The transcriptional repressor Mecp2 regulates terminal neuronal differentiation.

    FE did the protocol and project development, drafted the paper and made the MECP2 pathway, SC added database information and critical revision, EC contributed details in MECP2 gene variety information, ES added information about RTT diagnosis, use of diagnostic terms over time and clinical information, CE contributed bioinformatics details and critical revision, LC contributed to protocol and project development, manuscript editing and clinical information.

    National Center for Biotechnology InformationU. The gene in the neurotransmitter pathway which is known to be downregulated in the absence of functional MECP2 is GRID1 which could here be the link between mutation and phenotype [ 83 ].
