Aka monosuperocentroincisivodontic dwarfism.


Midline symmetrical upper central incisor.
The condition may also be associated with other midline disturbances such as

  • cleft palate
  • choanal stenosis or atresia
  • imperforate anus, or
  • umbilical hernia.
  • It is part of the spectrum of the holoprosencephaly malformation complex.
    Of importance is the association with hypoplasia of the sella, pituitary dysfunction, growth hormone deficiency and subsequent short stature.
