摘要
Rett syndrome (RTT) is a severe neurodevelopmental disorder affecting almost exclusively girls. Rett patients present an apparently normal psychomotor development during the first 6-18 months of life. Thereafter, they show a short period of developmental stagnation followed by a rapid regression in language and motor development. RTT is currently considered as monogenic X-linked dominant disorder due to mutations in the MECP2 gene, encoding the methyl-CpG binding protein 2. The aim of this study was to perform a mutational analysis of the MECP2 gene in a classical Rett patient. The results showed the presence of a novel point mutation c.C1142T (p.P381L) and two deletions at the heterozygous state: a novel deletion c.1075delTTC (p.S359) and a known one c.1157del44 (p.L386Q fs X2) in the C-terminal region of MeCP2.
