Both parents and their six siblings had pyramidal, taurodont or fused molar roots. Some of the patients also had hypotrichosis, an abnormal upper lip, thickened and wide philtrum, and/or juvenile glaucoma. Other features included entropion of the eyelid, syndactyly and clinodactyly of the fifth fingers.
