A<unk> , in the simplest sense, is a human<unk>  shape with a lower half that becomes relatively thin, approaching an appearance of a triangle with a tip facing downwards. It is not necessarily caused by any disease, but is common in individuals with Osteogenesis Imperfecta. In a broader sense,<unk>  encompasses a constellation of a hypoplastic<unk>  with prominent zygomatic arches, orbital hypertelorism, sunken cheeks, down-turned mouth, and occasionally brownish facial discolouration. This constellation is characteristic of Mulibrey nanism, but has also been described in Russell-Silver syndrome and Turner syndrome.
