The Silver-Russell Syndrome

A 38-month-old patient with Silver-Russel syndrome (SRS) and ambiguous genitalia had a 46,XY karyotype on leukocyte and fibroblast cultures. This is the third SRS child with ambiguous genitalia described in the literature. In a review of the findings in 148 reported cases of the syndrome, abnormalities occurring in over 50% of the cases are short stature, craniofacial dysproportion, low birth weight, term gestation, body asymmetry, incurved fifth digits, normal intelligence, short fifth digits, and down-curved corners of the mouth (shark mouth).
