Although mental retardation is one of the main features, various neurological symptoms such as hypotonia and seizures can occur. Here we report on a 18-year-old Turkish male patient who was diagnosed previously as Kabuki syndrome. Molecular genetic analysis showed a novel de novo heterozygous mutation (c.12964C>T [p.Gln4322*] ) in the MLL2 gene, that leads to the synthesis of a truncated protein. The aim of the present report is to increase the awareness of Kabuki Syndrome among adult neurologists and to present a previously unreported non-sense mutation in the MLL2 gene.
