Prenatal assessment of gestational age, date of delivery, and fetal weight. Some of the visible, physical signs of Beckwith-Wiedemann syndrome, such as a disparity in leg length or an enlarged tongue, may require surgical correction, but most of the characteristics become less apparent with time. Diagnosis of BeckwithWiedemann syndrome in children presenting with Wilms tumor. Less commonly, variants (also known as mutations) in the CDKN1C gene cause Beckwith-Wiedemann syndrome. For example, ultrasound imaging may allow assessment of organ size and overall size of the developing fetus and potentially reveal other findings that may be suggestive of BWS. Facial features of an affected patient can include a high broad forehead, a typically round face, widely spaced eyes (ocular hypertelorism), and an abnormally small jaw.
