Abstract
We describe a 46,XY newborn infant with Smith‐Lemli‐Opitz syndrome (SLOS) with multiple congenital anomalies including female external genitalia, a testis palpable in each labium majus, a cone‐shaped cervix, and normal vagina. Additional anomalies included cleft palate, total anomalous pulmonary venous return, and striking limb defects (ectrodactyly of the left upper limb, radial aplasia, and monodactyly of the right upper limb). To our knowledge, this is the first report of SLOS associated with limb deficiency and the third associated with total anomalous pulmonary venous return. Our patient demonstrates that limb deficiencies may be a rare component manifestation in this syndrome of multiple congenital anomalies.
