macrognathia

large chin

Definition (free text, please give PubMed ID)
I think macrognathia and prognathia should be different terms. Right now prognathia is also defined as relative prognathia. I think that is a contradiction. I think prominent jaw=macrognathia would be best suited to describe the chin of a patient with fragile X syndrome.

prognathia should be the opposite of retrognathia. Since retrognathia is not equivalent to small chin, prognathia should also not be equivalent to macrognathia.

Besides no terms exist over- and underbite
