hypotonia; delayed motor milestones (i.e. sitting up, crawling); recurrent infections; poor or absent speech; seizures; and/or spasticity. MECP2 duplication syndrome occurs when there is an extra copy (duplication) of the MECP2 gene in each cell. This is generally caused by a duplication of genetic material located on the long (q) arm of the X chromosome. The condition is inherited in an X-linked manner. Treatment is based on the signs and symptoms present in each person.MECP2 duplication syndrome is a genetic condition that occurs almost exclusively in males and is characterized by moderate to severe intellectual disability. Other signs and symptoms include infantile
