  • congenital heart defects in 10%; other malformations: ocular, dental, skeletal, urogenital in male patients; frequent infections.
  • mental retardation in 30-70 % of cases (from normal in 30% to severe retardation in 10%); siezures in 10%high-pitched voice; behaviour problems in 40%; most patients are 'hyperactive, shy, like music'.
    • Neoplastic risk haematological malignancies and pancytopenia in 10%, childhood myelodysplasia in particular; lymphomas
