Mutations in the MECP2 gene cause the severe neurodevelopmental disorder called Rett syndrome. Preliminary evidence suggests that MECP2 may be involved in a broader phenotype than classical Rett syndrome including preserved speech variants (PSV). Here we report clinical and mutation analysis of 18 PSV patients. Ten of them had a MECP2 mutation (55%). The clinical features of these girls have been characterized and two subgroups defined. All of them had slow recovery of verbal and praxic… Expand
