The syndrome is inherited as an X-linked trait and so affects mainly boys. Alternative names include MASA syndrome (MASA stands for mental retardation, aphasia, shuffling gait, and adducted thumbs), adducted thumb with mental retardation, congenital clasped thumb with mental retardation, and the Gareis-Mason syndrome.
