Rapp–Hodgkin syndrome was formerly thought to be a unique autosomal dominant disorder due to a P63 gene mutation. However, it was recently shown to the same disease as Hay–Wells syndrome.{{cite journal |vauthors=Clements SE, Techanukul T, Holden ST, etal |title=Rapp–Hodgkin and Hay–Wells ectodermal dysplasia syndromes represent a variable spectrum of the same genetic disorder |journal=Br.

It was first characterized in 1968.{{cite journal |vauthors=Rapp RS, Hodgkin WE |title=Anhidrotic ectodermal dysplasia: autosomal dominant inheritance with palate and lip anomalies |journal=J. Med.
