Rett syndrome (RTT) is an X-linked severe neurodevelopmental disorder mostly affecting female and is mainly caused by mutations of methyl-CpG-binding protein 2 gene (MECP2). MECP2, which has a crucial role for transcriptional repression and chromatin remodeling, consists of methyl-CpG binding domain (MBD) and transcriptional repression domain (TRD). Paternally imprinted distal-less homeobox gene 5 (DLX5), that has an important role for the development of gamma-aminobutyric acid (GABA)-ergic neurons, was identified as a target of MECP2 recently. We selected the 12 samples from the 40 RTT lymphoblast cell lines by a mononucleotide repeat polymorphism within the 3'UTR of DLX5. In 12 samples, 5 and 6 samples have the mutations located in MBD and TRD, respectively. No expression and 25-75% expression of the mutated MECP2 allele were detected in 4 samples with MBD mutation and 4 samples with TRD mutation. In this study, the expression of mutated MECP2 alleles was low especially in the samples with the MBD mutation suggesting the biased frequency of the cells during the culture. However, a sample with high expression of mutated MECP2 in TRD mutation showed bialleic expression of DLX5 suggesting loss of imprinting.
