Early recognition of rare hereditary syndromes can be vital. Early recognition of some rare syndromes may allow the anticipation of potentially harmful complications and reducing its damaging consequences. Early diagnosis of rare hereditary disorders also facilitates the provision of early genetic counseling which might contribute to preventing further cases which are expected to have a negative impact on the family. The occurrence of Beckwith Wiedemann syndrome in Iraq has not been reported or documented. In addition, to providing the historical documentation of this syndrome, particularly the early history of its documentation during the 1946s, 1970s, and 1980s, this book describes the first case of this rare syndrome in Iraq.
